A case of anti-wear project of primary air duct for boiler in a power plant in Tianjin
-
DeviceName:
The primary air duct of the boiler is used to convey dry pulverized coal and provide oxygen for the combustion of volatile components in the pulverized coal.
-
DeviceProblem:
Due to long-term operation, the welding seam of the primary air duct and the windward side of the pipe have serious erosion of the inner wall of the pipe. Severe parts will cause leaks in the air duct pipe. Therefore, anti-wear treatment should be done on the thinly-scoured parts in the pipe during the maintenance period.
