Explain with diagram explain power generation plant based on energy of natural gas
Answers
Compressor: Takes in air from outside of the turbine and increases its pressure.
Combustor: Burns the fuel and produces high pressure and high velocity gas.
Turbine: Extracts the energy from the gas coming from the combustor.
Combined cycle
The simple cycle stops here, however, the combined cycle extends beyond this to use more of the energy created in the combustion. The exhaust gases are made to flow towards the next unit, called the heat recovery steam generator (HRSG).[9] The HRSG is essentially a heat exchanger, in which the hot gases boil pre-heated water into steam. The steam then expands through a turbine, generating electricity. Once the steam has passed through, it condenses and is recycled through.
Cogeneration
Natural gas plants produce waste heat, like all heat engines. Sometimes this waste heat is captured to heat homes or for industrial uses. This process is known as cogeneration.
