INTRODUCTION

BADARPUR Thermal Power Station was established in 1973 in New Delhi.

.

B.T.P.S has 5 units:-Total capacity:- 705MW 3*95 MW=285 MW 2*210 MW=420MW

LAYOUT OF THERMAL POWER PLANT

CONSTRUCTIONAL DETAILS

The Badarpur thermal power plant is mainly divided into six parts:-

WATER TRATMENT PLANT

COAL HANDLING UNIT

STEAM GENERATOR

STEAM TURBINE

SWITCH YARD

COAL STORAGE PLANT

COAL STORAGE PLANTIn the coal storage plant we store coal as a fuel. Coal is delivered from the supply points to the firing section point. by using heat of the coal boiler water heated .

COAL HANDLING PLANTThe function of coal handling plant is automatic feeding of coal to the boiler furnace .

WAGON TIPPER

Boiler is an enclosed vessel in which water is heated and circulated until the water is turned in to steam at the required pressure.

MAINLY TWO TYPE OF BOILER IS USED IN PLANT 1- WATER TUBE BOILER 2- FIRE TUBE BOILER

BOILER

In these boilers water is inside the tubes and hot gases are outside the tubes. They consists of drums and tubes.

WATER TUBE BOILER

FIRE TUBE BOILER In fire tube boilers hot gases are passed through the tubes and water surrounds these tubes. These are simple & compact in construction.

TURBINE

A steam turbine heat energy of the fuel is converted in to mechanical energy and drives the generator.There are basically two types of turbine 1.Impulse turbine .2.Reaction turbine .

COOLING TOWER

Cooling Tower is used for cooling the

circulating water .

SWITCH YARD

Basic Component Of Switch Yard: 1. Isolator .2. Current x-mer.3. Potential x-mer.4. Circuit breaker .
