THERMAL POWER PLANT

A thermal power plant is usually defined by the type of fuel used to heat the water and create steam.

A fossil-fuel power plant is one that burns fossil fuels such as coal, natural gas or petroleum (oil) to produce electricity. Fossil-fuel power plants are designed on a large scale for continuous operation.

OPERATIONS OF COAL BASED THERMAL POWER PLANT

THERMAL POWER PLANT BASICALLY WORKS ON RANKINE PRINCIPLE.

•CONVEYOR: BELT TYPE ARRANGMENT USED TO TRANSMIT COAL FROM STORAGE.•PULVERISER/MIL: A PULVERIZER IS A DEVICE USED FOR GINDING COAL FOR COMBUSTION.•BOILER: COAL IS BURNED INSIDE THE CUMBUSTION CHAMBER OF BOILER TO HEAT THE WATER.•STACK: A CHIMNEY IS A SYSTEM FOR VENTING HOT FLURE GASES OR SMOKE FROM A BOILER.•CONDENSOR: STEAM AFTER ROTATING TURBINE COMES TO CONDENSOR WHERE IT IS COOLED AND TURNED IT BACK INTO WATER.•GENERATOR: AN ALTERNATOR IS AN ELECTROMECHANICAL DEVICE TO CONVERT M.E INTO A.C CURRUENT.•TRANSFORMER: A DEVICE WHICH TRANSFERS THE ELECTRICITY FROM AC CIRCUIT TO OTHER CIRCUITS.

ENVIORMENTAL IMPACT OF THERMAL POWER PLANT

BURNING COAL RELEASES MASSIVE AMOUNT OF TAXIC MATERIALS SUCH AS MURCURY AND ARSENIC.

CBTPP ARE RESPONSIBLE FOR 21% OF THE GREEN HOUSE GAS EMMISSION.

OFFICIAL FIGURES FROM CHINA SUGGEST THAT TPP USING COAL RELEAES 11MILLION TONS OF SO2 INTO THE AIR , MORE THEN 50% OF THE TOTAL EMMISSION IN THE COUNTRY.

WATER POLLUTION CONTROL MEASURES

COAL AND OIL SETTING PITS IN THESE PITS COAL DUST AND OIL

ARE REMOVED FROM THE EFFLUENT IN THE COAL HANDLING PLANTS BEFORE DISCHARGING INTO EFFLUENT TREATMENT PLANT.

NUTRALIZATION PITS: NEUTRALIZATION PITS ARE

PROVIDED IN WATER TREATEMENT FOR PH CONTROL FOR FURTHUR TREATMENT AND USE

EFFLUENT TREATMENT PLANT: CLEAN EFFLUENT FROM THE

PLANTS TO MEET THE ENVIORNMENTAL STANDARDS AND TO REDUCE INTAKE WATER REQUIRMENT.

COOLING TOWERS: COOLING TOWERS ARE PROVIDED

TO COOL DOWN THE WARM WATER COMING FROM THE PLANT.

NOISE POLLUTION THE ENTIRE PLANT IS SO

INSTALLED THAT THE RESULTANT NOISE REMAIN WITHIN THE PREMISES OF THE PLANT.

STANDARD FOR INDUSTRIAL ARE IS 70DB MAX OUTSIDE THE PROJECT PROPERTY BOUNDARY.

ALL THE EQUIPMENT IN THE PLANT ARE DESIGHNED TO NOT TO EXCEED THE LIMITATIONS OF 80-90DB (OSHA)

EAR PLUGS SHOULD BE USED BY THE EMPLOYERS WORKING IN THE PLANTS.
