A gas power plant consists of an air compressor, combustion chamber, gas turbine, alternator, and starting motor. Air is compressed and mixed with fuel in the combustion chamber, where combustion increases the temperature and pressure. The high-pressure combusted air expands through the gas turbine, rotating the generator to produce electricity. A starting motor initially rotates the compressor.
2. GAS POWER PLANTS
Working fluid is compressed AIR.
Employs a gas turbine.
Consist of :
COMPRESSOR
COMBUSTION CHAMBER
GAS TURBINE
ALTERNATOR
STARTING MOTOR
4. GAS POWER PLANTS
• Takes air from the atmosphere through air filter.
• Compresses the air to very high pressure.
• Compressor is rotated with the help of starting motor.
5. GAS POWER PLANTS
• FUEL OIL & COMPRESSED AIR is fed to combustion chamber.
• Fuel oil is burned inside the combustion chamber.
• This further increases the temperature and pressure of the compressed air
to a high value
6. GAS POWER PLANTS
• Compressed air at high pressure is expanded inside the turbine.
• Turbine rotates the generator coupled to it.
