This coal is transported up to the raw coal bunkers with the help of conveyor belts. 2. Crush House. After hand picking foreign material, coal is transported to the Crush house by conveyor belts where it is crushed to small pieces of about 20 mm diameter. The crushed coal is then transported to the store yard.
The initial process in coal based thermal power plant is coal handling.The Function of coal Handling Plant in thermal power plant is to receive, process, store, feed the coal bunkers consistently over entire life of the power plant. Coal is transported in thermal power station either by railways,roadways or rope ways.
It is around 75-80 % of ash generated in thermal power plant. In Coal power plant: In thermal power plant, coal is used as a fuel for generating Steam. After burning of coal 30 - 40 % of coal Consumption is converted into ash which need to be properly disposed-off from the thermal power plant. The operation of ash handling plants
