COAL HANDLING PLANT

FUNCTION - Automatic feeding of coal to boiler furnace

PROCESS - 1) Coal is unloaded from rail wagons in IV unit of

KSTPS

2) Coal is sent to crusher where coal is reduced to

very small size

Consumption of coal/Unit of electricity - 0.6 Kg

Consumption/day - 20000 tons/day

DEVICES -

1) Wagon Tripler - 5 (32 wagons/hr)

2) Vibration Feeders - Electromagnetic Type

3) Conveyor belts

4) Crushers - 6 (550 tons/hr)

ECONOMISER

Function-To extract some part of

heat from flue gases & heat the

feedwater

Process- Counter flow of flue

gases & water

Benefits- Increases efficiency


12/19

CONDENSER

To provide lowest economic heat rejection

temperature for the steam. Thus saving on

steam required per unit of electricity.

To convert exhaust steam to water for reuse

thus saving on feed water requirement.


13/19

COLLING TOWER

It converts hot water from into cold water.

Its purpose is to re use of the water.

Its increase the efficiency of plant. It increase the per capital investment of plant.

In K.S.T.P.S. only unit 6th and 7th has cooling

tower.

ELECTROSTATIC PRECIPITATOR

15

Used for the removal of suspended particles and fly ash fromindustrial flue gases

PRINCIPLE- Produces an electrostatic field which attracts the

ionized carbon particles and other such particulates which cause

environmental pollution.
