A. Coal Handling Plant Coal transported to the plant by the rail line and carrier trucks. This coal is transfer from the underground bunker to crusher by series of conveyer belt. In coal crusher coal size reduced up to ” after that coal transfer to the boiler’s coal bunker or coal yard. In the case of emergency the coal is fetch
The general rule in fire protection systems for conveyors is to locate Ember Detector (s) upstream from a change in direction (transfer to another conveyor) or a dust producing process or storage point. Hence, once the ember is detected, it can be extinguished before it enters the next process where it can cause a potential explosion.

The coal is first crushed into minute particles using equipment called pulverizes. The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for ...
