In a combined cycle power plant, the heat of the gas turbine's exhaust is used to generate steam by passing it through a heat recovery steam generator (HRSG) with a live steam temperature between 420 and 580 °C. The condenser of the Rankine cycle is usually cooled by water from a lake, river, sea or cooling towers.
A combined cycle, however, utilizes a Heat Recovery Steam Generator (HRSG) to harness this energy. A HRSG is a heat exchanger that transfers energy from the exhaust to a water system which then becomes steam. This steam is then used to drive a steam turbine, producing more electricity than just a simple cycle natural gas power plant alone.
