Power Plant Efficiency: A Key to Profitable Performance

In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed, such a configuration is common in a combined cycle power plant where a gas turbine and a steam
