Background
The heat recovery coke oven mainly comprises a carbonization chamber, a flue, an ascending flame path, a descending flame path, a primary air inlet and a secondary air inlet. The combustible materials of the heat recovery coke oven are subjected to secondary combustion in the oven body, namely, the combustible materials are firstly arranged at the top of the carbonization chamber, and the combustible materials are secondly arranged in a flue at the bottom of the carbonization chamber, and the heat required by coking of the coal cake is provided by the heat generated by the two combustion.
At present, a secondary air inlet of a heat recovery coke oven with a quadruple flame path structure is generally arranged at the bottom of the quadruple flame path, and a plurality of air channels are used for introducing air into the quadruple flame path, so that the resistance of the secondary air inlet with the quadruple flame path structure is large, the air quantity is insensitive to adjustment, and the adjustment workload is large. And because the combustible materials of the heat recovery coke oven enter the No. 2 flame path from the No. 1 flame path, a large amount of combustible materials are burnt in the No. 1 flame path, and the temperature uniformity of the four flame paths is poor.
