Combined cycle power plant t diagram. A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat converting it into mechanical energyon land when used to make electricity the most common type is called a combined cycle gas turbine ccgt plantthe same principle is also used for marine propulsion where it is called a combined gas and steam cogas plant. Combined cycle power plant. A combined cycle power plant or combined cycle gas turbine ccgt uses both a gas turbine and a steam turbine together to produce more electricity from the same fuel than a traditional simple cycle power plant. The waste heat from the gas turbine is routed to the nearby steam turbine which generates extra power.
The combined cycle power plant or combined cycle gas turbine is a gas turbine which generates electricity and recovering wastage of heat is used to make steam to generate the additional electricity via a steam turbine. Inner workings of a combined cycle power plant. Intro block diagram pv diagram ts property diagram proceses open cycle close cycle energy flow eqs of different components. There are three types of compressors.
The major components that make up a combined cycle are compressor gas turbine hrsg and steam turbine as shown in fig11. T s diagram of combined cycle power plant combined cycle. In a ccgt plant the thermal efficiency is extended to approximately 50 60 per cent by piping the exhaust gas from the gas turbine into a heat recovery steam generator. Combined cycle power plant as in name suggests it combines existing gas and steam technologies into one unit yielding significant improvements in thermal efficiency over conventional steam plant.
A combined cycle power plant uses both a gas and a steam turbine together to produce up to 50 percent more electricity from the same fuel than a traditional simple cycle plant.
