Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a spraying device for restricting the distribution of ceramic-based coatings on a boiler water-cooled wall. Background Art

[0002] The water-cooled wall is the main heat receiving part of the boiler. It is composed of several rows of steel pipes arranged or surrounded. The inside of it is flowing water or steam, and the outside receives the heat of the flame in the boiler furnace. It mainly absorbs the radiation heat of the high-temperature combustion products in the furnace, and the working fluid moves upward in it and evaporates due to heat. Since the flame temperature in the furnace is very high and the intensity of heat radiation is very high, it is necessary to spray a ceramic coating on the water-cooled wall to ensure that the water-cooled wall will not burn through during the operation of the boiler.

[0003] In the prior art, the spraying of ceramic-based coatings on water-cooled walls is mostly done manually, and the spraying quality is difficult to ensure, which affects the later use effect of the water-cooled walls. Moreover, the manual spraying process requires high-altitude operations, which poses certain safety hazards. Utility Model Content
