For example, coal-fired boiler, steam-fired boiler, etc., and its specific structure varies according to the use requirements. Coal-fired boiler has good performance and is more widely used, such as coal-fired boiler for power generation, coal-fired boiler for power, etc.
[0003] Coal-fired boilers need to add coal and other fuels to the boiler during operation. Coal bunkers are a common structure of coal-fired boilers, mainly used to transport coal into the boiler. The coal bunker discharges the coal added to the coal bunker to a specific location such as a conveyor belt through a discharging structure. The discharging structure is usually set in the shape of an enclosed square frame that communicates with the coal bunker. During the long-term use of the coal bunker, the coal contains moisture, which is easy to stick to the inner wall of the discharging structure to form lumps, causing the discharging channel of the discharging structure to narrow, and then causing coal blockage. Under conditions of high air humidity or high coal humidity, the coal discharge part is more likely to be blocked. Utility Model Content
