Wagon unloading systemUnload the coal
from wagon to hopper.
Hopper allows to pass coal pieces ≤ 200mm
From hopper coal fall on vibrator which is supported by roller.

Crushing systemCRUSHER HOUSE:-
Its main function to crush the coal to 20mm
Two typesPrimary crusher
o Rail crushero Rotary breaker
Secondary crusher

Conveying systemBelt are used to convey
coal from coal handling plant to furnance.
Specification:-Belt width : 1400mmSpeed : 2.2m/secTotal install power :
360kw Capacity : 1350/750
ton/hrNo. of conveyor: 38

BoilerIt is a closed vessel in which water under
pressure is convert into steam.Hot water or steam used to transfer heat to a
process.A boiler is always designed to absorb max
amount of heat released in process of combustion.
Furnace:- It is primary part of boiler where the fuel is burnt to liberate the heat energy.

Super heaterSuper heater consist group of tubes.The tubes are heated by the heat of
combustion gases during their passage from furnance to chimney.so the temperature increased.
Super heater remove the moisture from the steam leaving from the boiler tubes.

Steam TurbineIt is a machine in
which a shaft is rotated steadily by reaction of steam, air upon blades of a wheel.
When Steam is used then called steam turbine.

EconomiserEconomiser is device which recover the
heat from the flue gases on their way to chimney.
It increase the 10-12% efficency of the plant.

GeneratorGenerator•An electrical generator is a machine which converts mechanical energy into electrical energy through electro mechanical energy conversion .
•The generator is driven by directly coupled steam turbine at a speed of 3000 r.p.m.

Cooling SystemIn KSTPS hydrogen cooling system is
employed for generator cooling.Hydrogen is used because of its
superior cooling properties & low density.
Thermal conductivity of H2 7.3 times of air.
Seal oil system are used in turbine for less friction in bearing.
Water cooling also used for any kind of fire.

Ash handling plantIt can be divided into 3
sub plants :
Fuel and Ash plant
Air and Gas plant
Ash disposal & Dust collection plant.
