2. COAL HANDLING PLANT

• This plant have 3 parts...A. Wagon unloading system.B. Conveying belt system.C. Crushing system.

IMAGE OF COAL HANDLING PLANT

COAL LOADED BY TRAIN

• SOURCE OF COAL : COAL INDIA LTD. BCCL,SECL & ECL• MEANS OF TRANSPORTATION: - RAILWAY WAGONS • TYPE OF COAL : BITUMINOUS TAKEN TO COAL MILLS THROUGH CONVEYOR BELTS. CRUSHED INTO POWDERED FORM IN COAL MILLS. WITH THE HELP OF PRIMARY AIR FANS IT IS TAKEN TO BOILER.• COAL HANDLING PLANTCOAL HANDLING PLANT

A. Wagon unloading system

• Unload the coal from wagon to hopper.

• Hopper allows to pass coal pieces ≤ 200mm

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

C.Conveying system

• Belt are used to convey coal from coal handling plant to furnance.• Specification:-

– Belt width : 1400mm– Speed : 2.2m/sec– Total install power : 360kw – Capacity : 1350/750 ton/hr– No. of conveyor: 38

B. Crushing system

5. BOILER with FURNANCE

four part is connected with the boiler & furnance section

1. Water treatment plant.2. Ash handling plant.3. ESP(Chimeny)4. Turbine section.

8. WATER TREATMENT PLANT

• SOURCE OF WATER :- CHAMBAL RIVER

W.T.P. DIVIDED IN TWO PARTS :-

FILTERATION WATER PLANT DEMINERALISED WATER PLANT

ASH HANDLING PLANT

ASH HANDLING PLANT

ASH HANDLING PLANT

This plant can be divided into three sub plants as follows :-

1)Fuel and Ash Plant:-

2)Air and Gas Plant:-

3) Ash Disposal and & Dust Collection Plant:-

4. ELECTROSTATIC PRECIPITATOR

WORKING OF PRECIPITATOR

6.TURBINE

7.TURBO GENERATORDesigned for continuous operation at the

rated output.Directly coupled with steam turbine, rotated

at high speed of 3000 RPM.Two major parts:- (i) Stator (ii) RotorMajor parts of stator are (i) Stator frame. (ii)Stator core. (iii)Stator bars. (iv)Stator windings.

8.Cooling System• In 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.

10. Transformer

Various Transformers In KSTPS

– Generating Transformer– Unit Auxiliary Transformer (U.A.T.)– Station Transformer (S.T.)– Exciting Transformer– Earthing Transformer– Instrument Transformer
