The flame in the vertical flue of the coke oven is small
Thread Content
Our factory uses 6-meter coke ovens with dual flue channels. There is a strange phenomenon occurring: the flames in the even-numbered vertical flue channels on the machine side of each combustion chamber are weak, and the flames in the odd-numbered vertical flue channels on the coke side are also weak. Does anyone know what the cause of this is and how it can be adjusted?
The exchange isn’t proper; if that’s the case, check the travel switch or the displacement sensor
No, if the exchange is not proper, both the engine side and the combustion side should have a low heat output. Currently, in each combustion chamber, if it has a single flame channel, the heat output on the rising side is low; whereas with a dual flame channel, it’s the engine side that has a low heat output.
Is there any blockage in the horizontal pipes in the basement?
No, the whole furnace is like this.
Check the opening degree of the exhaust flap and the air inlet of the actuator!
It’s not an isolated phenomenon; in the entire furnace, the flames in the even-numbered vertical burners are weak, while those in the odd-numbered vertical burners are normal. In the coke side, the flames in the odd-numbered vertical burners are weak, and those in the even-numbered vertical burners are normal.
Based on your description, it seems there is still a problem with the device. Could it be the exhaust stroke? It pulls to one side, but not to the other side. A foolish opinion.
No, it’s the same in both directions.
