INTRODUCTION A thermal power station is a power plant in

which the prime mover is steam driven. It works on the RANKINE CYCLE. Damodar Valley Corporation (DVC) was

established in 1948 under an Act of Parliament for unified development of Damodar Valley covering an area of 24,235 sq km in Bihar and West Bengal.

DURGAPUR STEEL THERMAL POWER STATION is a Thermal Power Project of Damodar Valley Corporation (DVC) whose construction, commissioning activity is undertaken by Bharat Heavy Electricals Limited (BHEL).

THERMAL POWER PLANT

MAIN PARTS Coal handling plant Main generating plant Ash handling plant Switchyard

1.COAL HANDLING PLANT CHP handles the coal from its receipt to

transferring it to bunkers. Wagon tipplers are used to unload the

coal into underground conveyer belts from where they are transported to penthouse where suspended magnets are used to detect metals.

Crushers are used to crush the coal into small pieces which are then transported to coal storage via coal conveyer.

When the coal is to be used Pulverizer is used to grind the coal into dust.

2.MAIN GENERATING PLANT Here, the burning of coal starts. it contains various equipments which

help in generation of electric energy.

BOILERS

Pulverized coal is put in boiler furnance

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

Super-heater: Superheater is a component of a steam-generating unit in which steam, after it has left the boiler drum, is heated above its saturation temperature.

Reheater : Reheater is also steam boiler component in which heat is added to this intermediate-pressure steam, which has given up some of its energy in expansion through the high-pressure turbine.

Condenser : Condensers are heat exchangers which convert steam from its gaseous to its liquid state, also known as phase transition.

Cooling Towers: It is a tower- or building-like device in which atmospheric air (the heat receiver) circulates in direct or indirect contact with warmer water (the heat source) and the water is thereby cooled

Economiser : Function of economiser is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler.

Air preheater : It is a device used in steam boilers to transfer heat from the flue gases to the combustion air before the air enters the furnace.

Smoke stack : A chimney is a system for venting hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere.

STEAM TURBINE

Extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft.

uses multiple stages in the expansion of the steam.

GENERATOR

Converts mechanical energy into electrical energy.

Turbine is coupled with the Turbogenerator that normally spins at 3000 rpm in countries with 50 Hz supply frequency

The generated voltage is stepped up in Generator Transformer and the power is evacuated through transmission line feeders.

ASH HANDLING PLANT The main operations are: Removal of ash from furnace. Transfer of ash to a fill or storage. Disposal.Ash can be disposed of as: Dry ash system Ash slurry system

ELECTROSTATIC PRECIPITATOR

It is a device which removes dust or other finely divided particles from flue gases by charging the particles inductively with an electric field, then attracting them to highly charged collector plates.

4.SWITCH YARD

Hub of electrical power sources.

Exists in a generating station to coordinate the transfer of power between generators and transmission lines.

It contains current carrying conductors, transformers, circuit breakers etc.

CONCLUSION As the population is increasing, the

consumption of power is also increasing. In order to meet the needs of future

generation, power should be used efficiently.
