Technical Field

[0001] The utility model belongs to the technical field of boiler soot blowing, and in particular relates to an air soot blowing device for a boiler. Background Art

[0002] When the boiler is in long-term operation, ash and coke will accumulate on the heating surface, which will deteriorate the heat transfer. For the tail flue, due to the long-term accumulation of combustibles, re-combustion accidents may occur. Therefore, after the boiler has been running for a period of time, it is necessary to blow soot on the heating surface to clean it. There are three ways to blow soot on the boiler: compressed air soot blowing, steam soot blowing and chemical soot cleaning.
