Coal gas and air are mixed and combusted in the combustion chamber, heat is transferred to coal in the carbonization chamber in a heat conduction and heat radiation mode, the coal is converted into coke, and the energy consumption of the process accounts for 70% -80% of the energy consumption of the process. More than 10% of the total energy consumption of the coke oven is dissipated into the atmosphere through the surface of the oven body, and the highest temperature and the highest heat dissipation strength of a coal loading hole cover (or a smoke guide hole cover) and a fire observation hole cover are particularly adopted on all heat dissipation surfaces of the coke oven, so that the energy is wasted, and the environment pollution is caused.
The coke oven body above the carbonization chamber and the combustion chamber is called as the oven top, and the thickness of the coke oven body is determined according to the intensity of the oven body and the requirement of reducing the surface temperature of the oven top. The top area of the furnace is provided with a coal charging hole (a top charging coke oven) or a smoke guide hole (a tamping coke oven) which is communicated with the carbonization chamber and used for charging coal and guiding out raw coke oven gas generated during the dry distillation of the coal. In addition, a fire observation hole is arranged to lead to each vertical flame path for measuring temperature and checking flame, and the temperature and the pressure are adjusted according to the detection result. The brickwork in the furnace top area is usually built by refractory bricks, and the coal charging hole (smoke guide hole) or the fire observation hole are respectively provided with corresponding sealing covers. Wherein, the coal charging hole cover/smoke guide hole cover is directly contacted with the raw coke oven gas in the carbonization chamber, the temperature of the raw coke oven gas is about 830 ℃, the fire hole cover is directly contacted with the hot waste gas in the vertical flue, and the temperature of the hot waste gas is about 1000 ℃. The conventional coal charging hole cover/smoke guide hole cover and the conventional fire observation hole cover are integrally cast by adopting a common cast iron material, and the heat conductivity coefficient of the fire observation hole cover is higher, so that a large amount of heat of the carbonization chamber and the combustion chamber can be dissipated to the surface environment of the top of the coke oven through the corresponding hole covers, thereby not only causing energy waste, but also deteriorating the operation environment of the top area of the coke oven.
