    • Combined Cycle Gas Turbine
      • CostA 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. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power. Improve Performance with Digital

A heat recovery steam generator ( HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration) or used to drive a steam turbine ( combined cycle ). 2 Packaged HRSGs. 4 Once-through steam generator (OTSG)

  • OverviewCogeneration or CHP (combined heat and power) is the utilization of a heat engine for generating both heats as well as electricity simultaneously. In general, thermal power stations, as well as heat engines, do not change the existing energy into electrical energy. Most of the engines waste half of the main energy due to surplus heat.

A combined cycle scheme with single pressure is shown in Figure 22.12. The waste heat recovery boiler is made up from preheater, economizer, evaporator and superheater sections giving single high-pressure steam output. The limitations imposed by the approach temperature at the pinch point, as illustrated earlier, determines the boiler heat
