A combined cycle power plant consists of one or more gas turbines that drive generators and exhaust into a boiler called Heat Recovery Steam Generator HRSG. That generates steam for Rankine cycle unit. One of the principal reasons for the popularity of the combined cycle power plants is their higher thermal efficiency.
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. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power. Improve Performance with Digital.
A combined cycle CHP plant mainly comprises of a diesel engine otherwise a gas turbine which generates electrical power or mechanical power tracked through a heat improvement system which is useful in generating steam as well as drives a resultant steam turbine. Steam Turbine CHP Plant
05-05-2019· If you consider the coal plant and the combined cycle plant then, for building a combined cycle unit you require half of the money than that required for constructing the coal power plant. The abundance of fuel sources: For running the CCPP, you have large fuel resources like natural gas. Nowadays, biogas is also in use for operating the CCPP.
