How to solve the problem of boiler smoke pipe fire?

Find the cause. Is there combustible material coming in? Poor atomization? Incomplete combustion? Find the cause and deal with it according to the specific situation.

When the accumulation of combustible deposits on the surface of the boiler tube wall reaches a certain thickness, it is ignited at a certain temperature and falls off the wall and rushes out of the chimney to form sparks. This kind of spark is the most common and dangerous. The reasons for its generation include: (1) Poor fuel quality, soot deposits increase when inferior oil is burned; (2) The fuel injection equipment is not working properly, the fuel injection pump and injector are faulty, and the oil content in the exhaust gas increases due to incomplete combustion of the fuel; (3) The flue pipe of the exhaust gas boiler is blocked, the exhaust resistance increases, and the soot deposits increase. Preventive measures for chimney fires (1) Keep the combustion state in the furnace in good condition and strengthen management and monitoring; (2) Strengthen the technical management of the boiler, blow soot, wash the furnace and descale at specified intervals; (3) Regularly add chemicals to the exhaust pipe or boiler water pipe to remove carbon deposits and prevent scaling; Emergency measures in the event of a chimney fire (1) If the first type of sparks occur, immediately reduce the load or slowly stop, and resume operation after the cause is identified; (2) During operation, try to blow off the oily deposits in the exhaust system and burn them out; (3) Unless the fire is too fierce and the local smoke pipe is overheated, the load should be kept as high as possible;

Shut down the furnace for inspection, clean it, and re-adjust the combustion conditions.
