A coal-handling plant (CHP) in a thermal power plant is a front-end facility with a primary function, in a nut shell, that is to receive coal and transfer it to the coal bunker. The proper coal size should be what is acceptable to the mills/pulverizers for further processing.
The coal goes through a moderate grinding process and then is stored in a coal bunker. afterwards the coal is typically delivered to a power plant via rail or conveyor belt. The coal is transported by conveyor and tripper cars to coal hoppers / silos. These hoppers feed ball mills which is turn fedd the pulverized coal to the boilers.
The coal transport system of coal-fired power plants is the most serious site of coal dust pollution in power plants. The coal entering the plant until it is sent to the boiler bunker of the plant has to go through several production links, such as unloading, transporting, storing, taking, crushing, and blending.
