What factors cause misfiring under the exhaust gas tray and what are the corresponding corrective measures?
1. If the burning is not complete, the flame will dim; this can happen if the entire row of burners isn’t fully burned or if an individual burner’s flame dims. 2. Leakage from below; the carbonization chamber leaks into the combustion chamber, and the gas entering the furnace passes through vertical brick gas channels to reach the regenerative chamber. Solution: For cases where the furnace structure is not properly sealed, apply spraying, coating, or filling; address any issues with the heating system accordingly.
The most common cause is leakage from the brick gas ducts
Fire occurrence under the waste gas tray mainly happens in old coke ovens or those with poor construction quality; it is generally caused by severe leakage through the oven walls as well as significant leaks in the gas channels of the coke-fired bricks. Leakage in the oven walls can be addressed through spraying repairs or patching, but if the affected area is large, it becomes necessary to carry out oven repairs； Leaks in brick gas ducts can be addressed by spraying grout in the basement.
