Combined Cycle Plants Engaged in Thermodynamics

The most commonly used combination is a gas turbine and a steam turbine. In a simple cycle natural gas power plant, the exhaust from a gas turbine (usually 900–1200°F), is rejected into the atmosphere, wasting approximately 2/3 of the energy input. A combined cycle, however, utilizes a Heat Recovery Steam Generator (HRSG) to harness this energy.
