Embodiment Construction

[0007] specific implementation

[0008] The present invention provides a coke oven ascending tube divergent flame setting combustion and residual heat recovery method. Embodiment 1, the coke oven rising tube diverging flame setting combustion and residual heat recovery method includes a coke oven, a coke oven cover, an ascending tube, Riser top cover, movable fixing device, flame setting combustion waste heat recovery device, pipe network connection piping system, pipe network process control system, bridge pipe, flap and gas collector, the top of the riser tube is fixed by a movable fixing device. Flame setting combustion and residual heat recovery device. During the coke oven production process, the upper cover of the riser tube is in the closed position. The riser tube needs regular maintenance during the operation of the coke oven. The maintenance operation is performed from the top opening of the riser tube Yes, the movable fixing device can move the flame setting combust...

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...
