Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a furnace temperature measuring device for a coke oven having a large number of carbonization chambers.

Generally, a coke oven is formed of a furnace group in which independent carbonization chambers and combustion chambers are arranged alternately.

On the other hand, the carbonization time from when coal is charged into the carbonization chamber until it is combusted is also affected by external conditions such as the moisture content and particle size of the charged coal, but most of this is due to the temperature of the combustion chamber. determined by. Therefore, temperature measurement in the combustion chamber is one of the important requirements for controlling coke production conditions.

Conventionally, combustion chamber temperatures have been measured manually using optical pyrometers, and have to be measured over a relatively short period of time. Moreover, this temperature measurement method required a considerable amount of time even for an experienced person to measure one location, making it difficult to measure all combustion chambers in a short period of time, and there were drawbacks such as large human errors. .

In addition, temperature measurement methods that do not use an optical pyrometer include a method of measuring by installing a thermocouple in the upper space of the combustion chamber, or a method of measuring the temperature by installing a thermocouple in the upper space of the combustion chamber, or a method of measuring the temperature by installing a thermocouple inside the refractory on the top of the partition wall between adjacent combustion chambers or on the top of the hairpin. There is a method of measuring by installing a thermocouple. However, with the former method, the measured value pulsates due to various complex heat transfer mechanisms, as well as disturbances in the draft and gas flow velocity, making it difficult to grasp the value as a representative value of the furnace temperature. There is. In addition, the latter method measures the temperature inside the refractory, so it has the disadvantage that the measured value lags behind changes in the temperature inside the combustion chamber. This is not a satisfactory method of measurement.

The object of the present invention is to provide a device for measuring furnace temperature through the Furyu nozzle while running a measurement vehicle equipped with a thermometer using thermal radiation over the coke oven furnace, and to continuously measure each Furyu nozzle to be measured by the thermometer. It is an object of the present invention to provide a furnace temperature measuring device for a coke oven, which determines the maximum temperature among the temperatures at each point of a Furyu nozzle as the temperature of a combustion chamber in which the Furyu nozzle exists.

Another object of the present invention is to run, stop, etc. the measurement vehicle based on signals from a control room outside the reactor, and transmit measured data to the control room for data processing. It is an object of the present invention to provide a furnace temperature measuring device which enables transmission and reception between a measuring vehicle and a control room under any circumstances.

Still another object of the present invention is to provide a furnace temperature measuring device that can automatically charge a battery mounted on a measuring vehicle used for running the measuring vehicle.

Still another object of the present invention is to provide a furnace temperature measuring device that automatically opens and closes the furnace lid and measures the furnace temperature only for the Furyu nozzle to be measured.

The details of the coke oven furnace temperature measuring device of the present invention will be explained below. In order to measure the furnace temperature by measuring the light from the bottom of the furnace through the Furyu nozzle using a thermometer, for example, a measurement car equipped with a thermometer is run on a rail installed above the coke ovens in the direction of the furnace. It is necessary to open the lids of the Furyu nozzles one after another and take measurements. In this case, the temperature above the furnace other than the Friyu nozzle is also quite high, and the temperature measured through the Friyu nozzle with the lid open is relatively low around the opening and increases toward the center, reaching the highest temperature near the center. There is. Therefore, even if the measuring vehicle is run as described above and the temperature is measured through the Friyu nozzle to be measured, it is necessary to determine a measurement point in the opening of the Friyu nozzle and measure only the temperature at that point. However, there is a problem as to which point should be determined as the specific point, and even if the center of the aperture is determined as the measurement point, there are other problems such as that it is not easy to control the measurement to always be performed at that point.

For the above reasons, in the present invention, the temperature based on the largest value among the continuously changing data measured through the Furyu nozzle is determined as the furnace temperature through the Furyu nozzle. In other words, the measured quantity measured with a thermometer through the Furyu nozzle is sampled at small regular intervals, the data obtained at the first sampling is compared with the data at the next sampling point, and the smaller one is deleted. The larger one is stored, and the stored value is compared with the measured value at the next sampling point, and the same operation is repeated one after another.

In this way, the maximum remaining temperature at the end of all the measurements made with one Friyu nozzle is determined as the temperature at that Friyu nozzle. In other words, as shown in the block diagram of FIG. Sampled every certain distance traveled by the car,
After A/D conversion, the data is stored as a digital quantity in the storage/arithmetic circuit C, and the first stored data is compared with the next data in terms of magnitude, the smaller values are deleted, and the larger values are stored as they are. Further, the next sampled data is compared with the stored data and the smaller one is deleted. In this way, the largest value of one friu nozzle is left. This maximum value is sent to the control room D as the temperature data of that Furyu nozzle. Since the maximum values for the flue nozzles to be measured one after another are determined in this way, the temperature of each combustion chamber is determined based on these values. Furthermore, the obtained data is processed to display the temperature of each combustion chamber and to control the combustion state of each combustion chamber. A similar method can be used in which the analog outputs from amplifier A are sequentially compared in the data processing based on FIG. It is also possible to sequentially input the analog outputs from amplifier A and store only the highest value. Furthermore, the output of the thermometer 2 may be directly transmitted to the control room, and the maximum value may be determined by sampling in the control room based on the received analog quantity.

Note that the output from the thermometer does not change linearly with changes in the amount of light incident on the thermometer. Therefore, data processing may be performed after, for example, using a linearizer to make the output from the thermometer change linearly with respect to changes in the amount of light. If, as in this case, there is a time lag between the reception of light by the thermometer and subsequent processing, it is desirable to run the measuring vehicle at a speed slower than the response speed.

In the present invention, the measuring vehicle used during measurement runs independently and separately from the charging vehicle. Therefore, compared to the case where the measuring car and the charging car are integrated, measurements can be made at shorter intervals (for example, every 20 minutes). Also, temperature can be measured at any time if necessary. Therefore, the furnace temperature can be precisely controlled, which is effective in producing coke of uniform quality and in saving energy. In this way, in order to run the measurement car independently of the charging car, it is necessary to control it wirelessly from a control room or the like outside the furnace. On the other hand, the charging car has a length equal to the length of the furnace in the furnace length direction, and runs over the furnace at regular time intervals. Therefore, it is possible that the measuring vehicle collides with the charging vehicle. However, among the charging cars, those with a rigid frame structure have a raised bottom in the center, forming a hollow part of a certain height between the charging car and the upper surface of the furnace, as shown later. In the present invention, for reasons to be explained later, the measuring car is made to run along a rail laid in the direction of the furnace bed near the center in the furnace length direction. For this reason, when used in conjunction with a charging vehicle having a rigid frame structure, the measurement vehicle will run through the raised hollow area at the bottom of the charging vehicle without colliding with each other. However, when the measuring car went under the charging car, signals could no longer be sent and received between the measuring car and the control room.
It becomes impossible to control the measurement vehicle or receive data from the measurement vehicle. In the present invention, this drawback is eliminated by specific means as described below.

FIG. 2 shows the measuring wheel positioned below the charging wheel above the coke ovens. In Figure 2, E is a coke oven (E ₁ is a combustion chamber), F is a charging car with a rigid frame structure that has a hollow part F ₁ with a raised bottom in the center, and there is a charging car on top of the coke oven E. F
A rail 10 is laid through the hollow part F ₁ in the furnace direction, that is, in the running direction of the charging car F, and this rail 1
The measurement vehicle 1 travels along 0. G is a rising pipe installed in each carbonization chamber of coke oven E, H is a collecting main that collects coke oven gas through the rising pipe, and J is a collecting main installed at every point in collecting main H to collect coke oven gas. Breeder for emergency release, K, L, M are respectively charging car, measuring car 1,
This is a transmitting/receiving antenna attached to bleeder J.

As mentioned above, charging car F, measuring car I, and bleeder J are each equipped with transmitting and receiving antennas.
As shown in the figure, even when the measuring car 1 enters the charging car F, it can be controlled wirelessly from an external control room, and the data transmitted from the measuring car 1 can be reliably received in the control room. Generally, as shown in FIG. 2, when the receiving or transmitting measuring vehicle enters the loading vehicle and is out of sight from the control room, the signal is no longer received due to directivity problems. However, in the device of the present invention, since the information is transmitted and received via the antenna K attached to the charging vehicle F, the information can be transmitted and received without any problem. In particular, since there are a large number of bleeders J at each point interval, transmission and reception is possible by means of the antenna M attached to the bleeder J, regardless of the relationship between the measuring car and the charging car.

In the device of the present invention, the measuring car is made to run independently from the charging car. For this reason, the measurement vehicle runs using its own battery as a power source. Therefore, it is necessary to charge this battery at regular intervals. Therefore, the device of the present invention is equipped with a device that automatically charges this battery.

The automatic charging device included in the coke oven oven temperature measuring device of the present invention will be described below. FIGS. 3 to 5 are diagrams showing, for example, the vicinity of a measurement vehicle hangar, which is provided on the furnace outside the combustion chamber at the end of the furnace group, and in which a charging device and the like are provided. In these figures, 1 is a measuring car, 2 is a thermometer that uses heat radiation, such as a single color thermometer, a two-color thermometer, a three-color thermometer, a radiation thermometer, an infrared thermometer, etc. equipped on the measuring car, 3, 3 ' is a member for opening the lid of the Friyu nozzle, 4, 4' is a lid closing member for the Friyu nozzle (details of the lid opening/closing members 3, 3', 4, 4' will be described later), 5 is a battery mounted on the measuring car 1,
A pantograph 6 electrically connects the battery and the charging device by contacting a trolley, which will be described later. Reference numeral 7 denotes a first limit switch, and when this switch is turned on by a limit switch operation piece 7a installed in the hangar, it stops the measuring vehicle and also connects the battery 5, which is normally disconnected.
The pantograph 6 is configured to be electrically connected to the pantograph 6. Also, 11 is a hangar, 12 is a protective fence, 13 is a charging device, and 14 is a power cable 15
When the measurement vehicle 1 enters the hangar 11, the trolley is connected to the charging device 13 by the trolley and connected to the pantograph 6. 16 is a second limit switch that issues a signal for charging and water sprinkling when turned on by an operating piece 16a provided on the measuring wheel 1; 17 is a water sprinkler control panel operated by the second limit switch 16; 18; is a water sprinkler device.

As will be described in detail later, when the measuring car that measures the temperature through the Furyu nozzle while traveling along the rail 10 laid on the furnace as shown in FIG. 1
The limit switch 7 is turned on by the operating piece 7a, and the measuring wheel 1 stops. At the same time, the battery 5 and pantograph 6 are electrically connected.
Further, the hunter graph 6 and the trolley 14 are connected. As a result, current from the battery 5 flows to the charging device 13 through the pantograph 6, the trolley 14, and the power cable 15. Isn't it illustrated?
The charging device is equipped with a circuit that detects this current. On the other hand, the second limit switch 16 is turned on by an operating piece 16a provided on the measuring wheel 1. The circuit within the charging device is switched to charging by the signal from the second limit switch 16 and the detection of the current from the battery 5.
Thereby, the charging device 13 is connected to the power cable 1.
5. The battery is charged through the trolley 14 and pantograph 6. Also, in response to a signal from the second limit switch 16, a water sprinkler control panel 17 sprinkles water from a water sprinkler 18 onto the measuring wheel 1 to cool the battery. After a predetermined period of time has elapsed since the start of charging and the start of watering, the charging device 13 and the watering device control panel 1
Charging and watering are stopped almost simultaneously by the action of a timer installed inside the tank. The measurement vehicle whose battery has been charged in this manner is run along the rail 10 again to measure the furnace temperature. In addition, when it becomes necessary to measure the temperature before charging is completed and the measurement vehicle 1 is run, the measurement vehicle 1 is activated by an external command.
All you have to do is start the train. In that case, both the first and second limit switches are turned off, charging and watering are stopped, and the connection between the pantograph and the battery is also cut off.

An automatic charging system using the above-mentioned device is illustrated in FIG. 6. As shown in this figure, when the temperature measurement by the measurement car is completed, the measurement car enters the warehouse. When the vehicle enters the warehouse, the first limit switch 7 is turned on, the measurement vehicle stops, and the battery 5 and pantograph 6 are electrically connected. Furthermore, when the measurement vehicle stops at a predetermined position, the pantograph 6 and the trolley 14 come into contact. As a result, the battery 5 energizes the charging device 13, and this current is detected. On the other hand, the second limit switch 16 is turned on when the measurement vehicle enters the warehouse. Charging begins only after the above steps are completed. Also, the second limit switch starts watering. Charging and watering are stopped after predetermined times _t1 and _t2 , respectively, set by timers. After that, the measurement car departs and the measurement begins. After the predetermined temperature measurement is completed, the product enters the warehouse again and → is repeated.

It should be noted that instead of the limit switch and operating piece described above, a position detecting switch such as a photoelectric switch or a proximity switch may be used.

Next, the measurement of temperature by driving the measuring vehicle will be explained. In a coke oven, generally, of the burners in the combustion chamber, half of the combustion chambers that are connected in the longitudinal direction of the furnace burn, and after a predetermined time, the other half starts burning, and the combustion on the side that was previously burning is stopped. Combustion is carried out by alternating these steps. Furthermore, if the lid of the Furyu nozzle is opened during combustion, the temperature of the flame inside the combustion chamber must be measured, and the desired temperature of the bottom brick surface cannot be measured. Further, the temperature of the combustion chamber is low at the extruder side, increases with a certain temperature gradient toward the exit side from the kiln, and becomes the highest at the exit side from the kiln. The average temperature of the combustion chamber is at the center in the furnace length direction. Therefore, measuring the indoor temperature from the Furyu nozzle closest to the center on the side where combustion is stopped will not be affected by the combustion in the room, and will also measure the average temperature of the combustion chamber. desirable for this reason. Therefore, it is best to measure the row of Furyu nozzles that are closest to the center and lined up in the direction of the furnace cluster when combustion has stopped.

There are typically two types of structures for coke oven heating flame channels. One of them is a structural style typified by an Otto furnace. For example, in Fig. 7, the odd-numbered combustion chambers 21, 23, .
a, 23a... are burned first, and even-numbered combustion chambers 22, 24... are burned on the outlet side 22b, 24b..., and after a certain period of time (for example, 20 minutes), the above combustion is stopped, and the other side is burned. In other words, the odd numbered side is the one exiting the kiln.
For even numbers, the extruder side burns. In other words, when considering only the Furyu nozzle closest to the center of the combustion chamber among the halves divided from the center of each combustion chamber, the burning portion becomes staggered as indicated by the broken line N or P in FIG. For this reason, if you want to continuously measure the temperature of each combustion chamber in the direction of the furnace using a thermometer installed on the vehicle, the vehicle should travel along the broken line N or P in Figure 7 for the part where combustion has stopped. It is necessary to do so. However, it is practically difficult to open and close the lid and perform measurements without stopping the measurement vehicle while the vehicle is running in this manner.

In the case of an Otto furnace, in the case of an Otto furnace, every other Furyu nozzle lined up on broken line Q or R in FIG. When the combustion location is changed, measurements are taken in the opposite direction for every other remaining fly nozzle. That is, in FIG. 7, measurements are taken for the odd-numbered combustion chambers along the broken line Q from the combustion chamber 21,
When it reaches the other end, it is moved in the opposite direction and the even numbered parts are measured. For this reason, in the above example, the lids of the even-numbered combustion chambers are not opened during the forward journey, and the lids of the odd-numbered combustion chambers are not opened during the return furnace.

Next, in the structural style typified by the Karl Steel furnace, the same side of each combustion chamber (for example, the extruder side 21a, 22a...) is first burned, and after a predetermined period of time (for example, 20 minutes), the opposite side (the kiln side) is burned. Output side 21
b, 22b...) are burned alternately at regular intervals. Therefore, in the case of this type of furnace, it is sufficient to sequentially open the lids, measure, and close the lids of all the Furyu nozzles in the same direction on the side where combustion is stopped.

As mentioned above, measurements in the furnace group direction vary depending on the type of furnace, and in the case of an Otto furnace, measurements must be made every other time. In the present invention, measurements can be made in any of the above cases as described in the following embodiments.

Figures 8 and 9 are diagrams showing only the measurement vehicle, Figure 8
The figure is a side view, and FIG. 9 is a plan view. These figures are mainly for explaining the opening and closing of the lid and the temperature measurement through the flue nozzle, and therefore the battery, limit switch, etc. are omitted.
The lid opening members 3, 3' shown in these figures are the first
As shown in Figure 0, support plates 3a and 3' are plate-shaped.
It is supported horizontally by a. The lid closing members 4, 4' have a structure as shown in FIG. 11, are supported by support plates 4a, 4'a, and can be rotated only in the direction indicated by the arrow in FIG. 8.

12 and 13 are diagrams showing the lid of the Furyu nozzle used in the present invention, and FIG. 12 is a plan view, and FIG.
Figure 3 is a side view. In these figures, 40 is a cylindrical opening of the Friyu nozzle, 41 is a lid, 42 is a bearing part whose one end is fixed to the side surface of the cylindrical opening 40 of the Friyu nozzle and holds a shaft 43, and 44 is a lid opening/closing part fixed to the shaft 43. The plate 45 is an arm fixed to one end of the shaft 43, and the plate 46 is a lever connected to the arm 45 by a shaft 47, and is mounted so as to be rotatable by the shaft 47. Also arm 4
5 and the shaft 47 are fixed or rotatable.
48 is a stopper provided on the arm 45.

As shown in FIG. 14, the lever 46 of the above-mentioned lid structure is partially composed of a straight portion 46a and a curved portion 46b. Shitatetsu Lever 4
6 from the direction of arrow U, the lever 46
tries to rotate around the shaft 47, but the straight portion 46a hits the stopper 48 and pushes it further, so the lever 46 and the arm 45 move together around the shaft 43.
rotates with. As the shaft 43 rotates, the lid opening/closing part 44, which is fixed to the shaft, rotates around the shaft 43 to open the lid 41. On the other hand, when the lever 46 is pushed in the direction of the arrow W, only the lever 46 rotates around the shaft 47.

In the present invention, the lid having the structure as described above,
In the case of an Otto furnace, they are installed in alternating directions as shown in Figure 15, and in the case of a Karl Steel furnace, they are installed in the same direction as shown in Figure 16.
As shown in FIG. 15 or 16, the measurement wheel 1 described above moves along the rails laid on the furnace bed, and repeats the sequence of sequentially opening the lid of only a predetermined Furyu nozzle → measuring → closing the lid.

The measurement of the combustion chamber by the furnace temperature measuring device of the present invention will be explained below.

First, we will discuss the case of measuring in the direction of the furnace furnace in an Otto furnace. Now, the extruder side 22a, 24 of the even-numbered combustion chamber 22, 24...
a... is burning, while the odd-numbered combustion chamber 2
It is assumed that the kiln exit sides 21b, 23b, etc. of Nos. 1, 23, and so on are burning. In that case, for example, if measurement is performed on the extruder side, odd-numbered 21a, 23a...
...has stopped burning and can be measured. In this case, as shown in FIG.
If the vehicle is run from point 1, the measuring vehicle will first reach the fuel nozzle of the combustion chamber 21. Here, since this Furyu nozzle is provided with a lid as shown in FIG. 15, the lid opening member 3 provided on the measuring wheel comes into contact with the lever 46 of the lid. In this case the first
In Figure 4, the lid opening member 3 is pushed towards the lever 4 from the direction of arrow U.
Since you will press 6, the lid will be opened as already explained. When measuring car 1 moves further, thermometer 2
passes over the furnace nozzle with the lid closed, and the temperature at the bottom of the furnace is measured. Subsequently, the lid opening member 3' passes the position of the lever 46, but since the lid is already in the open state, there is no change. Furthermore, since the lid closing member 4 comes into contact with the opened lid, this is pushed to close the lid. As the measuring car advances further, combustion chamber 2
The lid opening member 3 comes into contact with the lever. However, since the even-numbered combustion chambers are provided with lids in the opposite direction to the odd-numbered combustion chambers, the lever is pushed in the direction of arrow W in FIG. 14. Therefore, only the lever 46 rotates and the lid is not opened. Similarly, the lid opening member 3' also passes through. In this way, the measuring wheel passes over the combustion chamber 22 without opening the lid and therefore without measuring the temperature. For the odd-numbered combustion chambers where combustion has stopped, the lid is opened, the temperature is measured, and the lid is closed, while for the even-numbered combustion chambers where combustion is in progress, the gas simply passes through. .

In this way, travel in the direction of the furnace group is completed, and temperature measurements of all combustion chambers where combustion has stopped are completed. After that, when the combustion point is replaced, if the measurement car is run in the opposite direction, the operation of opening the lid → measuring temperature → closing the lid will be performed for the even-numbered combustion chamber where combustion has been stopped. Regarding the odd-numbered combustion chambers, the lids are not opened, closed, or measured at all, and they are simply passed through. In this way, when the measuring wheel returns to the starting position, temperature measurements for all combustion chambers are completed.

Next, the case of a Karl Steel furnace will be explained. In the case of this type of furnace, a lid is attached to the flue nozzle used for measurement, as shown in FIG. 16. In other words, the lids are attached to each combustion chamber in the same direction. Then, when the combustion on the side with the lid that can be opened and closed by the measuring wheel according to the present invention is stopped, the measuring wheel may be moved in the direction in which the lid can be opened and closed. For example, in the case of Fig. 16, when combustion on the extruder side is stopped, the furnace temperature in all combustion chambers can be measured by moving the furnace from the combustion chamber 21 side in another direction toward the furnace. . Therefore, there is no round trip measurement,
It is sufficient to return the measurement car to the starting position after the end of the measurement and before the start of the next measurement.

In addition to measuring the combustion chamber temperature, the lid may be opened to observe or clean the interior of the chamber. If the measuring wheel runs while the lid remains open, the lid closing member 4 may come into contact with the open lid. Particularly, as shown in FIG. 17, if the lid closing member pushes the lid 41 further in the direction of opening the opened lid, this may cause a malfunction. However, in the device of the present invention, as shown in FIG. 11, the lid closing member 4 can be rotated in the opposite direction to the direction in which the lid is closed, so that the device can run without any trouble. If the measuring car runs further, the lid opening member 3'
Since the user presses the lever 46 and closes the lid, the lid that was forgotten to be closed is closed, and temperature measurement from this Friyu nozzle is prevented. There is no fear that the upper lid closing member 4' will hit the lid.

FIG. 18 shows the structure of another furnace cover used in the apparatus of the present invention. This lid consists of a lid attachment member 51 fixed to the cylindrical opening 40 of the Friyu nozzle and a shaft 5.
The cover 53 is rotatably attached to the cover 2 and has a hook 54, and the cover is configured to be closed by a spring 55.

In the Friyu nozzle having a lid with such a structure, the lid can be opened by pushing the hook 54 in the direction of the arrow as the measuring car travels, using contact plates 56 provided before and after the thermometer of the measuring car. . When the lid is opened, a thermometer passes over the Furyu nozzle and measures the furnace temperature. After the measurement, the contact plate 56 is removed from the hook 54, and the lid is automatically closed by the action of the spring 55.

When a lid of this construction is used for an Otto furnace, it is necessary to alternate the mounting direction of the lid for the reasons already explained. In other words, hook 54 is the first
In Figure 8, it is necessary to alternately arrange the items on the left side and the items on the right side. When the measurement vehicle is running, it is necessary to open every other lid using the abutting plate 56 and measure the temperature by opening and closing only the lids of combustion chambers where combustion has stopped. Therefore, the contact plate 56 may come into contact with the hook 54 from the opposite direction (the direction opposite to the arrow in FIG. 18), which is undesirable. However, it is sufficient if the abutment body 56 can be rotated only in the direction opposite to the direction of movement. As a result, when the contact plate 56 comes into contact with the hook 54 in the direction of the arrow in FIG. 18, the hook 54 is pushed to open the lid.
On the other hand, when the contact is made from the direction opposite to the arrow, the hook 54 does not move, so the contact plate rotates and can move forward as it is. Therefore, even if the position of the hooks is alternately changed in the Otto furnace, it can be moved and measured without any problem.

Furthermore, the one shown in FIG. 19 differs from the one shown in FIG. 18 only in that the cylindrical opening does not protrude above the furnace, but is otherwise substantially the same. Therefore, the lid can be opened and closed using the abutment plate having the above-described structure. In order to open the lids of the structures shown in FIGS. 18 and 19, a roll or an L-shaped arm may be used as the contact plate instead of a plate-like one. The lid shown in FIG. 20 has a quartz glass 57 installed at the upper end of the cylindrical opening 40 via a gasket. In this case, since the light from the bottom of the furnace can be measured through the quartz glass 57, a lid removing device is not necessary. However, since it is desirable to clean the surface of the quartz glass during measurement, it is preferable to provide a cleaning device instead of the lid removing device. FIG. 21 shows an example of this cleaning device. This cleaning device has cylinder 6
1, a cleaning section consisting of a piston rod 62 with a brush 63 attached to its tip, a conduit 64 connected to a nozzle 65 via a flexible tube 66, a cylinder 67, and a piston rod 68 with the nozzle 65 attached to its tip.
These are installed near the thermometer 2 of the measuring vehicle 1. When the apparatus of the present invention equipped with such a cleaning device is operated as described above, the brush 63 of this cleaning device sweeps the quartz glass surface, and pressurized air from the conduit 64 is directed diagonally toward the quartz glass surface from the nozzle 65. The quartz glass surface can be cleaned and measured by spraying it from the surface.

In addition, in the case of a Friyu nozzle covered with quartz glass as shown in Fig. 20, the temperature of both the Friyu nozzle in the burning area and the Friyu nozzle in the area where combustion has stopped is measured through the transparent quartz glass. It turns out. However, which side of the combustion chamber to burn and to stop combustion is changed at predetermined time intervals under correct control, so which side of the measured temperature data is the one during combustion. It is easy to determine which data is from when combustion is stopped. Therefore, it is only necessary to select data when combustion is stopped during data processing.

In addition to the above-mentioned devices, temperatures can also be measured using the device of the present invention even in structures that have been conventionally used. In other words, in the case of such conventionally commonly used lids, a device with a magnet at the tip is used as the lid removing device, and the magnet moves back and forth until it deviates from the line connecting the thermometer and the Friyu nozzle. An appropriate mechanism may be provided.

When measuring the temperature of a combustion chamber equipped with a conventionally commonly used lid using a furnace temperature measuring device equipped with a lid removing device as described above, the temperature of the fuel nozzle should be measured by running a measuring vehicle. After placing the thermometer above the thermometer, stop once, lower the magnet to hold the lid by suction, and pass it through the Friyu nozzle while reciprocating the lid together with the magnet to a position outside the line connecting the thermometer and the Friyu nozzle. Measure temperature. After the measurement, the measuring car is moved to the top of the next Furyu nozzle to be measured, stopped, and then the measurement is carried out in the same manner.

The coke oven furnace temperature measurement device of the present invention uses the maximum value of the data measured through the friue nozzle as the furnace temperature of the combustion chamber where the friue nozzle is located, so it is possible to use different measurement data at each point of the friue nozzle opening. It is easy to determine the furnace temperature, and it is also possible to measure the furnace temperature even when there is fluctuation in the temperature at each point. Therefore, the temperature measurement time is short and the device is simple. In addition, since the measuring car used for measurements runs independently from the charging car, it is possible to measure at short time intervals, and it is also possible to measure at any time, allowing extremely precise furnace temperature measurements. control becomes possible. Moreover, by using it on a charging vehicle with a rigid frame structure, the measurement vehicle can be run regardless of the movement of the charging vehicle, and by providing an antenna on the charging vehicle and the bleeder, the measurement vehicle and equipment can be moved. It is possible to send and receive data and command signals regardless of the mutual positional relationship of vehicles. Furthermore, the battery mounted on the measuring vehicle can be charged automatically and safely using the automatic charging device. Further, in temperature measurement, the operations of opening the lid, measuring, and closing the lid can be automatically and successively performed only for a specific Furyu nozzle to be measured.
