Combined cycle power plant By Dr Aklilu A klilu Tesfamichael
Combined Power Plants A combine power plant is a system consists of a gas turbine power plant ,Heat Recovery Steam Generator (HRSG), generators, controls, and a steam turbine power plant. The gas exit temperature should be above 120 C to prevent corrosion

More Ways to Increase Power plant Thermal Efficiency
A combined gas turbine based power plant is essentially an electrical power plant in which a gas turbine and a steam turbine are used in combination to achieve greater efficiency than would be possible independently.
Since the increase in power output occurs without the input of additional heat, the overall thermal efficiency is increased.

Combined heat and power or cogeneration efficiency
Industries often require both power and heating loads
If the steam is used for heat (e.g. heating buildings, industrial process) then the plant would be referred to as a cogeneration plant or combined heat and power.

Example A simple steam power plant operates between pressures of 10 kPa and 4 MPa with a maximum temperature of 400ºC. The power output from the steam turbine is 100 MW. A gas turbine provides the energy to the boiler; it accepts air at 100 kPa and 25ºC, has a pressure ratio of 5, and a maximum temperature of 850ºC. The exhaust gases exit the boiler at 350 K. Determine the thermal efficiency of the combined Brayton-Rankine cycle.
