Blasting of the viewing holes on the coke side of the coke oven
Thread Content
When viewed from the side, the fire hole opens with a popping sound and flames appear, only to disappear moments later. The machine side is relatively better; the rising pipe is on the coke side, and the gas collection pipe pressure is 150. The mechanical focal suction force is 180 Pa. Could it be that the pressure in the gas collection pipe is too high, forcing the gas from the carbonization chamber into the combustion chamber and causing a leak? Please tell me, it’s urgent.
Considering the excess gas, it could be residual gas or caused by leakage through the furnace walls
There is leakage, but it’s not certain yet whether it’s coming from the brick gas duct or from the carbonization chamber.
Also, the pressure at the fire viewing port is on the high side, around 15–20 PA.
Pressure 15 pa. What’s the connection?
Increase the correlation between suction and blasting? Thank you, please explain.
If there is a loud roaring sound on the coke side, and considering the pressure at the viewing hole, it can be inferred that the suction force on the coke side is low. The reason for this is that with low suction force, less air enters, resulting in incomplete combustion of the gas; as a result, a large amount of combustible gas accumulates above the viewing hole. When you open the cover of the viewing hole, this combustible gas comes into contact with air, forming a mixture that can cause roaring sounds. If it is an isolated burst, consider it to be caused by a series leakage
