This process flow diagram represents the generation of electricity from a gas-steam power plant. This power plant is divided into two segments the gas side of power plant and the steam side of power plant. Steam has vapors in it and the high-pressured steam with no vapors is called gas which has far more energy in it. The gas is produced by an air compressor that pressurizes the steam to be fed into a gas turbine the turbine rotates the shaft of the generator to produce electricity. The exhaust of the gas turbine is cooled by a heat exchanger which yields steam that can also be used in a steam turbine which again works on the same principle to produce electricity.
