[0002] The boiler water wall is the evaporation heating surface of the boiler furnace, consisting of many parallel tubes. It is the main heat-receiving component of the boiler, directly in contact with the flame, and absorbs the radiant heat from the furnace.

[0003] The water in the water-cooled wall tubes absorbs the radiant heat from the furnace flame, causing part of the water to evaporate into steam. This is an important link in steam generation and plays a key role in the steam output of the entire boiler. In industrial boilers, a large amount of steam is used to drive steam turbines to generate electricity or provide heat energy for industrial production processes. The steam generated by the water-cooled wall is the starting part of the subsequent steam cycle. The boiler water-cooled wall requires spraying equipment for corrosion protection operations. Existing spraying equipment requires pouring liquid materials of different materials into the mixture, which is easily mixed with solid particles and causes pollution, reducing the safety of the spraying equipment.

[0004] Therefore, the spraying equipment needs to be redesigned and modified to effectively prevent the problem of solid particles easily mixing into the spraying equipment due to the need to pour liquid materials of different materials into the spraying equipment and cause pollution.
