Introduction to Coal handling plant
In a coal based thermal power plant, the initial process in the power generation is “Coal Handling”. So in this article i will discuss the overall processes carried out at a Coal Handling plant in a coal based thermal power generating station. T he huge amount of coal is usually supplied through railways. A railway siding line is taken into the power station and the coal is delivered in the storage yard. T he coal is unloaded f rom the point of delivery by means of wagon tippler. It is rack and pinion type. T he coal is taken f rom the unloading site to dead storage by belt conveyors. T he belt deliver the coal to 0m level to the pent house and f urther moves to transfer point 8. T he transf er points are used to transf er coal to the next belt. T he belt elevates the coal to breaker house. It consists of a rotary machine, which rotates the coal and separates the light dust f rom it through the action of gravity and transf er this dust to reject bin house through belt. T he belt f urther elevates the coal to the transfer point 7 and it reaches the crusher through belt. In the crusher a high-speed 3-phase induction motor is used to crush the coal to a size of 50mm so as to be suitable f or milling system. Coal rises f rom crusher house and reaches the dead storage by passing through transfer point 8.
Equipment used in a coal handling plant
1. Pull chord swit ch
A series of such switches are arranged in series at a 1m distance on the side of conveyor belt. T he power supply to rotor of the conveyor belt is established only if all switches in series are connected.
2. Vibrat ing f eeder
T he coal stored in a huge hub is collected on the belt through vibrations created by the vibrating f eeder.
3. Flap gat es
T hese are used to channelize the route of coal through another belt in case
