Is not completely dry-distilled in a coke oven (not shown), so even during cooling in this red hot coke dry fire extinguishing system, the undistilled fraction in the coke (1) is a flammable gas such as H 2 or CO. (G), inside the hopper (2) or in the cooling chamber (6)
(6 ') stays in (6 "). In particular, since the temperature of the hopper (2) charged with the red hot coke (1) is high, unburned combustible gas (G) is generated and retained remarkably. When the concentration of this combustible gas (G) is high, opening the lid (3) of the hopper (2) in order to charge the red hot coke (1), the combustible gas and the outside air in the hopper (2) are opened. May mix with (air) and cause an explosion.
A part of the cooling inert gas (5) circulating in the red hot coke dry fire extinguishing equipment is sucked out by the blower (35) and taken out, and supplied into the hopper (2) through the bypass pipe (30), After diluting the combustible gas (G) generated in the hopper (2) with the inert gas for cooling (5), it is led to the cyclone (34) → blower (31) → combustion chamber (32) where it is burned. By using non-combustible gas, the combustible gas concentration in the hopper (2) is lowered until the next coke charging. At this time, the combustion air is supplied from the air supply pipe (33) to the blower (31) → the combustion chamber (32).
The cyclone (34) is installed in the blower (31).
And to protect the combustion chamber (32).

When handling coke, the combustible gas generated from the coke can be made sufficiently incombustible, but when handling coke with high reactivity and high temperature (about 1100 ° C) such as coke for iron making. In addition, CO 2 gas and H 2 O gas, which are present in the inert gas (5) and still have a high temperature and high reactivity even on the grate (4) in the cooling chamber (6), will be described later. The reaction as shown in the formula occurs, combustible CO gas and H 2 gas are generated, and the entire cooling gas becomes combustible gas.

った。C + CO 2 → 2CO …… C + H 2 O → CO + H 2 …… C is coke. Therefore, the circulating gas passing through the main duct (40) becomes flammable. Moreover, since the flow rate of the non-combustible hopper process gas coming from the combustion chamber (32) is overwhelmingly four times as large, the composition after merging becomes flammable. Therefore, the diluent gas that enters the hopper (2) from the bypass pipe (30) is always flammable, and the inside of the hopper (2) is always in a flammable atmosphere, which may cause an explosion at the time of charging the coke.

促進される。During the above operation, the cooling inert gas (5) comes into contact with the hottest red hot coke (1) passing through the first cooling chamber (6) and is contained in the cooling inert gas (5). CO 2
When non-combustible gas components such as H 2 O and H 2 O react with red hot coke (1) at the same temperature (see formula), and the inert gas for cooling (5) comes out above the coke (1) (cooling chamber ( 6)), when a large amount of flammable components CO
And H 2 are included. However, in the present invention,
This cooling inert gas (circulation gas) (5) joins and mixes with the hopper processing gas containing combustible gas sent from the hopper (2) on the downstream side of the cyclone (8) and the blower (31), It is sent to the combustion chamber (32) together with the air supplied from the air supply pipe (33), and combustible components CO and H 2 are burned in the combustion chamber (32). Therefore, the combustion chamber (32) →
After passing through the exhaust heat boiler (11), the mixed gas has a completely nonflammable composition, and a part of this mixed gas is cooled from the midpoint of the cooling nonuse gas discharge pipe (12) to the cooling inert gas. The conduit (5) → blower (7 ″) → blower (35) → bypass pipe (30) is introduced into the hopper (1) while the combustible gas (G) generated in the hopper (2) is blown (31). ), And joins and mixes with the cooling inert gas (5) that has exited the cyclone (8) as described above, so that the flammable atmosphere in the hopper (2) quickly becomes a non-combustible atmosphere, There is no danger of explosion when charging the coke (1) into the hopper (2), and the coke (1) is completely charged, while protecting the combustion chamber (32) and the high temperature blower (31). Therefore, it is desirable to install a dust remover such as a cyclone on the upstream side of each device. When the (32) previously filled with solids, such as catalyst or molded brick, the combustion reaction is accelerated.

As shown in Fig. (I), every time the coke (1) is charged into the coke charging hopper (2), the gas temperature at the combustion chamber outlet, that is, the inlet gas temperature of the exhaust heat boiler (11) is periodically changed. fluctuate. This periodic fluctuation in gas temperature is due to the fact that the amount of combustible gas components (CO and H 2 ) generated from the red hot coke is highest immediately after charging the hopper (2) and then gradually decreases. ing. When load fluctuations of the exhaust heat boiler (11) are a problem, it is advisable to do as shown in FIG. That is, the heat storage chamber (37) is provided immediately after the combustion chamber (32). By doing so, the fluctuation of the outlet gas temperature of the combustion chamber (32) is reduced as shown in Fig. 3 (II).

When a cooling inert gas circulating in a main body circulation system including a cooling chamber has finished heat exchange, a part of the branching gas is branched and supplied to a coke charging hopper. After mixing with the flammable gas generated in the coke charging hopper,
It is taken out from the coke charging hopper, then the mixed gas is mixed with the circulating gas of the main body circulation system discharged from the high temperature part of the cooling chamber, and then introduced into the combustion chamber to remove the combustible components in the mixed gas to the air.
