KOTA

By : Aman Agrawal 09EVVME005 B.TECH. 4th Year Mechanical Engg. Vit (East), Jaipur

It was established in 1983.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.

INTRODUCTION OF THE THERMAL POWER PLANT

INSTALLED CAPACITY

Main Parts of Kota Super Thermal Power Station• Principle• Layout• Coal handling plant• Boiler• Super heater• Steam Turbine• Economizer• Generator• Water Treatment Plant• Ash handling plant• Control Room

TECHNICAL LAYOUT OF KSTPS

Coal Handling Plant

Coal handling plant section

• Wagon unloading system• Crushing system• Conveying system

Wagon unloading systemUnload the coal

from wagon to hopper with the help of wagon Tripler.

Hopper allows to pass coal pieces ≤ 200mm

From hopper coal fall on vibrator which is supported by roller.

Conveying systemBelt are used to convey

coal from coal handling plant to furnace.

Specification:-Belt width : 1400mmSpeed : 2.2m/secTotal install power :

360kw Capacity : 1350/750

ton/hrNo. of conveyor: 38

Crushing systemCRUSHER HOUSE:- It

consists of crushers which are used to crush the coal to 20 mm size.

Two typesPrimary crusher

o Rail crushero Rotary breaker

Secondary crusher

BoilerIt is a closed vessel in which water under

pressure is converted into steam.Hot water or steam used to transfer heat to a

process.A boiler is always designed to absorb

maximum 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.

Figure Boiler

Super heaterSuper heater consists group of tubes.

The tubes are heated by the heat of combustion gases during their passage from furnace 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 it is called steam turbine.

It works on Modified Rankine cycle.Kinetic

Mechanical Energy

EconomizerEconomizer is a device which recover the heat from the flue gases on their way to chimney.

It increases the 10-12% efficiency of the plant.

•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.

Water Treatment PlantPressure filter removes

undisclosed impurities from raw water.Carbon filter removes excess

chlorine from clarified water.D.M. plant removes dissolved

impurities from clarified water.Conductivity ,pH & silica

content of this water must be checked time to time.D.M. water must be in the ratio of 1:8

Ash Handling PlantIn thermal plants

25% is furnace bottom ash and 75% is pulverized fuel ash.

Electrostatic Precipitator is used in ash handling plant to remove fly ash.
