Coke oven riser tube emission flame setting combustion and waste heat recovery method thereof

Abstract

The invention relates to a coke oven riser tube emission flame setting combustion and waste heat recovery method thereof. The invention put forwards the factors that the cleaning production of the coal is difficult, the factors are as follows: the emission flame combustion is formed in the production process of the current coke oven, the emission flame randomly drifts back and forth following a wind direction at oven top, and the potential risk of burn is brought to an operator, and widespread thermal pollution is brought to the surrounding environment; the coke powder can blow out following the draft of the flame to form the dust pollution, and the invention further puts forwards a solution adopting the method. Through the method disclosed by the invention, the organized setting type combustion can be performed on the waste crude gas in emission unorganized combustion, and the potential risks and thermal pollution caused by the emission combustion are eliminated; the setting combustion process can combust the coke powder carried by the crude gas to reduce or eliminate the pollution of the coke powder carried by the crude gas; the waste heat recovery of the combustion process can be simply performed, and the energy conversation and emission reduction effect is obvious.

Description

technical field [0001] The invention relates to a coke oven riser divergent flame setting combustion and residual heat recovery method, which is suitable for the flame setting of the coke oven before and after coke pushing to the divergent combustion of the riser gas in the riser before coal charging and the use of waste heat in the combustion process. It belongs to the technical field of energy saving and emission reduction. Background technique [0002] At present, in the production process of the coke oven, it is necessary to close the flap, open the cover of the rising pipe, and open the furnace cover for a long period of time before and after coke pushing in the coke oven and before adding coal. There will be a large amount of gas coming out from the top and the roof of the furnace, forming divergent flames to burn, and the divergent flames will randomly follow the wind direction of the furnace roof and float back and forth, which will bring safety hazards of burns to t...

[0002] At present, in the production process of the coke oven, it is necessary to close the flap, open the cover of the rising pipe, and open the furnace cover for a long period of time before and after coke pushing in the coke oven and before adding coal. There will be a large amount of gas coming out from the top and the roof of the furnace, forming divergent flames to burn, and the divergent flames will randomly follow the wind direction of the furnace roof and float back and forth, which will bring safety hazards of burns to the workers and bring a lot of heat to the surrounding environment. Pollution, coke powder will float out with the flame suction, forming dust pollution, which will bring difficulties to the clean production of coal
