INTRODUCTIONIt was established in 1973 , comprising of 2 units of each of capacity 110 MW.It is located at the left bank of the CHAMBAL River at the upstream of KOTA BAIRAJ.1st & 2nd units are of 110 MW each. 3rd ,4th &5th units are of 210 MW .6th & 7 unit of 195 MW.Total generation capacity (110+110+210+210+210+195+195) =1240 MWFavorable condition

Abundant quantity of clean cooling water.Good transport facility Concentration of load in Kota region due to large number of industries.

LAYOUT

Layout of thermal power plant

Coal handling plant

Layout Coal Handling Plant

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.

Kinetic Energy

Mechanical power

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.

Electrical Energy

Mechanical power

Generating Transformer

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.
