Flue gas leakage from the coke oven
Thread Content
The coke oven is now smoking through its door; what should we do in this situation?
Personal opinions: 1. Cleaning of the furnace door and frame: Manual cleaning or mechanical methods such as spiral milling cutters or high-pressure water are both effective options at present. 2. It is necessary to maintain an appropriate pressure in the gas collection pipes and reduce pressure fluctuations. 3. Inspect the protective plates to prevent gaps where they meet the exposed surfaces, and fill those gaps with grout promptly
What was said on the second floor is very good; our drivers here also use yellow mud for sealing, and it works quite well
In addition to the answer given on the second floor, I would like to add that it is necessary to clean the graphite in the rising pipe promptly to prevent blockages in this pipe; otherwise, poor drainage of waste gas can cause smoking from the furnace door
Smoke coming from the furnace door: Is the furnace door clean? Is the furnace frame clean? Is the pressure in the gas collection system too high? Is there good coordination between the operator and the person responsible for removing coal from the furnace (is the furnace door aligned properly)? Is too much coal loaded?
The key is the pressure in the gas collection system, which should be measured regularly. It is also necessary to improve the operations related to taking the product out of the furnace, such as cleaning the furnace frame and door, using coal slurry to block smoke, maintaining the quality of the furnace door, and thoroughly cleaning up any residual coke and coal
