Roof space temperature

How can the temperature in the furnace top area be reduced? Please advise, experts
Generally speaking, the temperature in the furnace roof space is related to the heating level of the furnace itself, as well as the uniformity of the upward heating. However, the heating level itself cannot be changed; therefore, in practice, we generally control the temperature by regulating the height of the coal cake.
At the same time, effort must be put into the handling of flat coal after it is filled, and the degree of shrinkage of the coal should also be appropriate.
For rammed coke ovens, since flat coal is not used, how can the temperature in the roof space be reduced?
Ensure the height of the coal cake, maintain the distance between the coal cake and the top of the furnace, and reduce the amount of graphite used
Uneven coal can lead to an increase in graphite at the top
By a ramming coke oven, I mean one in which the coal pellets have already been compacted in the coal bin and leveled by manual effort, before being fed into the carbonization chamber – rather than using a leveling rod to level the coal as is done in top-charging coke ovens.
Increase the coal cake height, lower the standard temperature, reduce the pressure at the monitoring holes
What I’m talking about is manually leveling the floating coal on the top layer of coal briquettes. This work is very important.
It’s a rammed coke oven; there’s no need for leveled coal, as the loose coal is leveled manually. It’s by using the height of the coal briquettes to control the temperature in the space; to lower the temperature there, that’s what needs to be done. Even heating of the coal cake from top to bottom relies, in the end, on proper basic management. It’s the temperature.
Load coal according to the standard; loading more can lower the furnace top temperature.
