(6'') Remains within (6'''). In particular, since the temperature of the hopper (2) into which the red-hot coke (1) is charged is high, the generation and retention of uncarbonized combustible gas (G) is significant. When the concentration of this flammable gas (G) is high, when M (3) of the hopper (2) is opened to charge red-hot coke (1), the flammable gas inside the hopper (2) and the outside air ( (air) may cause an explosion. For this reason 2
A part of the cooling inert gas (5) circulating through the hot coke dry extinguishing equipment is sucked out by the blower (35) and supplied into the hopper (2) via the bypass pipe (30). .

(発明が解決しようとする問題点)

コークスを取り扱う場合には、冷却室(6)内にある火
格子(4)上でも未だ高温で1反応性が非常に高くて。(Problems to be Solved by the Invention) In the conventional flammable gas treatment method of the red-hot coke dry extinguishing equipment shown in FIG. When handling coke at a temperature of 1,100°C, the flammable gas generated from the coke can be made sufficiently nonflammable, but it is highly reactive like steelmaking coke, and may not be used at high temperatures (approximately 1100°C). When handling coke, it is still hot and highly reactive even on the grate (4) in the cooling chamber (6).

H2 gas is generated and the entire cooling gas becomes flammable gas.

て。C+CCh→2CO・・・・・・・・・■C+H20
→CO+H2・・・・・・■C is coke. The circulating gas passing through the main duct (40) therefore becomes flammable. Moreover, since the flow rate is overwhelmingly large, about 4 times as much as the nonflammable hopper processing gas coming from the combustion chamber (32), the composition after one merge becomes flammable. Therefore, the dilution gas entering the hopper (2) from the bypass pipe (30) is always flammable, and the inside of the hopper (2) is always in a flammable atmosphere.

After being mixed with the combustible gas generated in the coke charging hopper, it is taken out from the coke charging hopper and the mixed gas is then discharged from the high temperature section of the cooling chamber through the circulation system of the main body. This article relates to a method for treating flammable gas in red-hot coke dry extinguishing equipment, which is characterized by mixing gas with gas and guiding it into a combustion chamber to burn the combustible components in the mixed gas with air. An object of the present invention is to provide an improved method for treating flammable gas in a red-hot coke dry extinguishing equipment, which allows safe charging of coke into a hopper.

After the gas is supplied and mixed with the flammable gas generated in the coke charging hopper, it is taken out from the coke charging hopper and the mixed gas is then discharged from the high temperature section of the cooling chamber as the circulating gas of the main body circulation system. The mixed gas is then introduced into a combustion chamber where the combustible components in the mixed gas are combusted with air.

Therefore, the flammable atmosphere in the hopper (2) quickly becomes a non-flammable atmosphere, and there is no danger of explosion when charging the coke (1) to the hopper (2), making it possible to safely charge the coke (1). It will be done. In order to protect the combustion chamber (32) and the high-temperature blower (31), it is desirable to install a dust remover such as a cyclone upstream of each device. Also, if the combustion chamber (32) is filled with a catalyst or solid material such as irregularly shaped bricks.

This periodic fluctuation in gas temperature is due to the fact that the amount of combustible gases (Co and H2) generated from the red-hot coke is highest immediately after charging into the hopper (2), and then gradually decreases. There is. If the load fluctuation of the waste heat boiler (11) becomes a problem as described above, it is preferable to do as shown in FIG. 2. That is, the combustion chamber (3
A heat storage chamber (37) is provided immediately after 2). In this way, the fluctuation in the outlet gas temperature of the combustion chamber (32) is reduced as shown in Fig. 3 (I
