Coal Handling in Thermal Power Plant

Coal requirements per day of a large thermal plant are very large. A 600 MW power plant handles about 7200 tons of coal per day. Therefore, one of the major requirement of a power plant is to reduce the cost of handling of coal from the point of its origin upto the furnace of boiler where it is burnt.

Coal Bunker

A coal-handling plant (CHP) in a thermal power plant is a front-end facility whose main function is to receive coal and transfer it to the coal bunker with a proper coal size acceptable to mills. Coal source, quality/size, transportation mode, main plant capacity, topography, etc., are a few factors that dictate the CHP design concept.
