Description

DETAILED DESCRIPTION OF THE INVENTION The present invention allows fuel to transition from a raw combustion state to a vaporization combustion state by simply supplying combustion air without using any rotating members, thereby continuing good vaporization combustion over a long period of time. This invention relates to improvements in vaporizing burners.

Conventionally, an upper tube with an air outlet on one side and a vaporization chamber inside, and a lower tube with a gas chamber inside and a combustion part that raises vaporized combustion flames against the upper tube are bent pipes. The inner wall of the bent pipe has a receiving wall for receiving the sent fuel, and a combustion plate on which the received fuel is placed directly below the upper pipe. Prior to this application, there was no vaporization burner that could automatically shift the fuel from a raw combustion state to a vaporization combustion state simply by blowing forced air without requiring a preheating heater etc. For example, it is described in Japanese Patent Application Laid-Open No. 54-137131 and is well known.

By the way, in the case of the above-mentioned known vaporizing burner, since it was attempted to achieve the transfer means for flowing the supplied fuel down onto the combustion dish by forced air, forced air is blown toward the air outlet side from the start of combustion. As a result, the upper tube is preheated to the vaporizing atmosphere temperature within a shorter time because cold air flows through the upper tube and cools the upper tube from the start of combustion. The problem arose that it was not possible.

In view of the foregoing, the present invention provides a mixed gas generator having an air blowing port on one side through which the tip of an oil pipe for vaporization and combustion is seen, and having a vaporization chamber inside, and a gas chamber inside. , the center of the top surface is recessed to serve as a combustion dish,
A large number of gas ejection holes are bored on both the left and right sides of the above-mentioned combustion dish, and the gas chamber body is connected in communication with a gas chamber body equipped with a combustion section that ejects vaporized combustion flames from below or from the sides toward the mixed gas generator. At the same time, the tip of the raw combustion oil pipe is exposed through the air supply window on the combustion pan provided on the surface of the gas chamber body disposed below the mixed gas generator, and the fuel is supplied to the combustion pan. Energy saving can be easily achieved by supplying the oil directly through the live combustion oil pipe without relying on forced air blowing, and at the same time, the mixed gas generator is cooled by the flow of cold air. The object of the present invention is to provide a vaporizing burner that can prevent this from occurring, quickly preheat to the vaporizing atmosphere temperature, and thereby accelerate the rise time from a live combustion state to a vaporizing combustion state. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a vaporizing burner according to the present invention will be described below with reference to preferred embodiments shown in the accompanying drawings.

The embodiment shown in FIGS. 1 to 3 is a vaporizing burner capable of ejecting a vaporizing combustion flame from below toward the mixed gas generator, and 1 has an appropriate cross-sectional shape. It is a mixed gas generator,
The mixed gas generator 1 has an air outlet 2 on one side and a vaporizing chamber 3 formed hollow inside. Reference numeral 4 denotes a gas chamber body whose interior is formed into a hollow end-shaped gas chamber 5 having an appropriate cross-sectional shape, and the mixture gas generator 1 and the gas chamber body 4 have a generally horizontal U-shape as a whole. They are connected in a continuous manner and are integrally formed. A combustion section 7 is formed on the upper surface of the gas chamber body 4, which is positioned below the mixed gas generating body 1 with a flame interval 6, for emitting vaporized combustion flames to the mixed gas generating body 1. The combustion part 7 is formed by recessing the center part of the upper surface of the gas chamber body 4 corresponding to the lower position of the mixed gas generator 1, and forming the recess into a combustion plate 9.
A large number of gas ejection holes 8 are formed in parallel in the convex surfaces on both the left and right sides of the combustion dish 9.

A fuel backflow stopper 10 of an appropriate height is provided at the position of the air outlet 2 provided on one side of the mixed gas generator 1, and at the starting end of the vaporization chamber 3, fuel is sent into the vaporization chamber 3 in a trickling manner. The end of either one of the gasification combustion oil feed pipe 11 that sprays oil or the gasification combustion oil feed pipe 11a that sprays fuel into the vaporization chamber 3 in the form of a mist is opened and is visible.

A partition wall 12 is erected on the tip side of the combustion dish 9 formed in the shape of a recess to seal the partition wall 1.
An air supply window 13 for supplying secondary air for combustion toward the combustion dish 9 is opened at a suitable height position of the combustion chamber 2. Reference numeral 14 denotes a live combustion fuel pipe for supplying fuel from the air supply window 13 onto the combustion dish 9, and the live combustion fuel pipe 14 shown in FIG. 1 is of the drip type. This may be a raw combustion oil pipe 14a that can supply fuel to the combustion dish 9 in the form of a spray, as shown in FIG.

In addition, if a suitable blower pipe 15 is connected to the air supply window 13 as shown by the chain line in FIG. 1 to blow forced air, the fuel can be evenly distributed and supplied onto the combustion plate 7 more effectively. The mixed gas generator 1 generates a uniform raw combustion flame.
It is something that can be set ablaze.

The one shown in FIG. 4 shows another example of a vaporizing burner that can blow vaporizing combustion flames from the side toward the mixed gas generator. Generally, the gas chamber body 4' connected to the mixed gas generator 1' is formed into a branched shape such that the gas chambers 5', 5' are spaced apart and tapered from side to side. A mixed gas generator 1' is positioned in the middle of gas chambers 5', 5' which are spaced apart from each other. Then, the surfaces of the left and right gas chambers 5', 5' facing the sides of the mixed gas generator 1' are made into combustion parts 7', 7', and a large number of gas ejection holes 8', 8' are bored therein. A combustion plate 9' is disposed directly below the gas generator 1'.

The gas chamber body 4' is formed into a branched shape as described above.
A partition wall 12' is disposed on the tip side of the gap to partition the tip side of the gap, and at the same time an air supply window 13' is opened at an appropriate height position of the partition wall 12'.
The raw combustion oil feed pipe 14' inserted from 3' is shown above the combustion dish 9'. Note that reference numeral 11' denotes an oil supply pipe for vaporization and combustion, the tip of which is visible on the starting end side of the vaporization chamber 3 of the mixed gas generator 1'.

Next, the operation of the present invention will be explained using the vaporizing burner shown in FIGS. 1 and 2.

Now, when it is desired to bring the fuel into a vaporized combustion state rather than a raw combustion state using a serious gasification burner, first, an appropriate amount of fuel is sent onto the combustion dish 9 via the raw combustion oil feed pipe 14, and it is live-combusted. At the start of this raw combustion, secondary air for combustion is taken in through the air supply window 13 without combustion, so that the raw combustion is complete. When combustion is performed live in this manner, the mixed gas generator 1 disposed above is quickly preheated by the live combustion flame, and the temperature inside the vaporization chamber 3 is reduced to a sufficient vaporization atmosphere to vaporize the fuel. Bring to temperature. When this happens, forced air is blown into the vaporization chamber 3 from the air outlet 2 side, and at the same time, the vaporization combustion oil feed pipe 1
When fuel is fed from 1, the fuel is quickly evaporated and vaporized by the heating effect while being blown in the direction of the arrow by forced air in the vaporization chamber 3, and the vaporized gas generated is mixed with the forced air. The mixed gas becomes a complete mixed gas, is pressurized into the gas chamber 5 of the gas chamber body 4, and is combusted with fumes through the numerous gas ejection holes 8, which is the combustion section 7, to intensely heat the mixed gas generator 1 from below. Thereafter, the fuel fed into the vaporization chamber 3 from the vaporization combustion oil feed pipe 11 is quickly evaporated to generate mixed gas. Therefore, if a situation arises in which vaporized combustion flames are blown up from the combustion section 7 as described above, even if the oil supply operation from the raw combustion oil feed pipe 14 is stopped, the vaporized combustion flames cannot be properly raised. This allows the vaporization combustion state to continue for a long period of time.

In short, the present invention comprises a mixed gas generator 1 which has an air outlet 2 on one side through which the tip of an oil pipe 11 for vaporization and combustion is visible, and has a vaporization chamber 3 inside, and a gas chamber 5 inside. None, the center of the upper surface is recessed to form a combustion dish 9, and a large number of gas ejection holes 8 are bored on both left and right sides of the combustion dish 9 to direct vaporization and combustion toward the mixed gas generator 1 from below or from the side. Even if the gas chamber body 4 is connected in communication with the gas chamber body 4 provided with the combustion part 7 that blows out flames, the Since the tip of the oil feed pipe 14 for raw combustion is visible above the combustion dish 9, there is no need to waste the effort of blowing forced air into the mixture gas generator 1 from the air outlet 2 when starting raw combustion. In order to save energy, the fuel is sent to an appropriate amount through the raw combustion oil pipe 14 that is exposed through the air supply window 13 to quickly generate raw combustion, and the mixed gas generator 1
It is possible to preheat the mixture gas and obtain a good mixture gas, and since cold forced air does not flow through the mixture gas generator 1 at the start of live combustion, the temperature inside the vaporization chamber 3 can be quickly vaporized. By raising the temperature to the ambient temperature, the transition time from the raw combustion state to the vaporization combustion state is significantly shortened, and the effectiveness of the vaporization burner can be fully exhibited.
