An Integrated Solar Combined Cycle (ISCC) is a hybrid technology in which a solar thermal field is integrated within a combined cycle plant. In ISCC plants, solar energy is used as an auxiliary heat supply, supporting the steam cycle, which results in increased generation capacity or a reduction of fossil fuel use.
The curve plots 501F combined cycle efficiency vs. time, with simple cycle power rating and heat rate shown at intervals along the development timeline. (Ed. Note: As of this edit in 2016, MHI offers the M501F3 at 185 MW and Siemens offers the SGT6-5000F (a.k.a. 501F) at 242MW, approximately the rating of the original 501G, below.)
Cogeneration or combined heat and power (CHP) is the use of a heat engine [1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use.
Some larger installations utilize combined cycle generation. Usually this consists of a gas turbine whose exhaust boils water for a steam turbine in a Rankine cycle. The condenser of the steam cycle provides the heat for space heating or an absorptive chiller. Combined cycle plants with cogeneration have the highest known thermal efficiencies ...
Large (land-based) electric powerplants built using this combined cycle can reach conversion efficiencies of over 60%. [ 1 ] If the turbines do not drive a propeller shaft directly and instead a turbo-electric transmission is used, the system is known as COGES (combined gas turbine-electric and steam).
Load-following power plants can be hydroelectric power plants, diesel and gas engine power plants, combined cycle gas turbine power plants and steam turbine power plants that run on natural gas or heavy fuel oil, although heavy fuel oil plants make up a very small portion of the energy mix. A relatively efficient model of gas turbine that runs ...
Mohave Generating Station, a 1,580 MW steam–electric power plant near Laughlin, Nevada fuelled by coal. A steam–electric power station is a power station in which the electric generator is steam-driven: water is heated, evaporates, and spins a steam turbine which drives an electric generator.
Micro combined heat and power, micro-CHP, μCHP or mCHP is an extension of the idea of cogeneration to the single/multi family home or small office building in the range of up to 50 kW. [1] Usual technologies for the production of heat and power in one common process are e.g. internal combustion engines , micro gas turbines , stirling engines ...
