The problem of coke oven gas dilution

When using coke oven gas for heating, it is necessary to add inert gas to deplete the coke oven gas to solve the problem of high heating of the coke oven. I would like to ask if adding appropriate steam to the coke oven gas will cause harm to the furnace body. I sincerely ask all experts to give me some advice, thank you:) :)
Doesn't anyone know? ? :'( :'( :'(
Is that a coking plant? I haven't heard about steam? The temperature can be controlled by the gas volume, and can be added as a friend to chat
Haha, I work in a coking plant. I asked about adding steam to the coke oven gas to dilute the coke oven gas and to solve the problem of low temperature in the upper part of the vertical fire channel:) :)
Depleted gas generally adds combustion exhaust gas from coke ovens or other kilns to the gas to reduce the concentration of combustible substances. Generally, the method of adding steam is not used. Firstly, it is difficult to control, and secondly, the steam will cause a series of side effects after condensing in the gas pipeline. ； At the same time, when it is discharged as combustion exhaust gas, excessive water vapor content is also detrimental to the flue and chimney.
I have never heard of depleted gas and adding steam. The one on the first floor is really innovative. Aren't you afraid of damaging the coke oven? We usually add blast furnace gas to coke oven gas. If you are worried about it being unsafe, you can add nitrogen instead. Never add steam.
The coke oven itself has a mixing structure and is discarded. Why bother mixing steam? Besides, steam is easy to condense. But I appreciate your idea and it is worth supporting. If there is a device that can adjust the calorific value of the gas at will, it should be beneficial to the operation of the coke oven.
