Outline
To solve the problem of coal dust leakage from the coal handling system of coal-fired power plants，by comparing different solutions，dust prevention and control equipment and technologies were adopted including curved coal fallout pipe，fully enclosed dust-removing guide chute，pulsed bag dust collector，and wet dust collector. The optimized solution for dust reduction and prevention of the coal handling system was put forward. The dust prevention and control system covering the whole operation process of coal fuel ″turning，stacking，picking，and transporting″ was formed and was applied in Suizhou Power Generation Project. The results of the study show that the method effectively reduces the spillage of coal dust in all aspects of coal fuel transfer and basically realizes a dust-free operating environment and clean fuel transport. It provides a feasible dust prevention technology for controlling the coal dust pollution produced during the operation of the coal handling system.
