Description

Technical Field

[0001] The utility model belongs to the technical direction of preventing coal sheds, and specifically relates to a coal bunker unblocking device which can avoid coal sheds. Background Art

[0002] Shelf coal will cause the coal powder particles to enlarge and reduce the combustion rate of coal powder, which will in turn affect the combustion efficiency of the boiler. Avoiding shelving coal can ensure the fineness and uniformity of coal powder, improve combustion efficiency and reduce energy waste. If shelving coal appears during the combustion process, it will lead to incomplete combustion and produce a large amount of harmful gases such as carbon monoxide and nitrogen oxides, which will not only pollute the environment, but also cause corrosion to the boiler and chimney. Avoiding shelving coal can reduce environmental pollution and extend the service life of equipment. Shelving coal will cause the boiler load to decrease and increase fuel consumption and operating costs. Avoiding shelving coal can ensure the stable operation of the boiler, reduce operating costs and improve economic benefits.
