Combined - Cycle Gas & Steam Turbine Power Plants Henrik Nielsen, Judy Warner, Rolf Bachmann, Rolf Kehlhofer

A traditional combined cycle power plant uses a normal gas turbine engine burning a normal fuel like natural gas, and then uses the exhaust gases to drive a steam turbine. Steam turbine power plants operate on a Rankine cycle. The plant, to be fueled by natural gas, will utilize a combined cycle power plant technology with a high efficiency gas-turbine (GT) and heat recovery steam generator (HRSG). With GTCC type power generation, gas and steam turbines are used in combination to generate electricity in two stages, utilizing high-temperature exhaust gas from the gas turbine. GE Energy and Mitsubishi Heavy Industries, Ltd. (MHI), two manufacturers of power generation equipment, have signed a memorandum of understanding (MOU) to co-develop the “next generation” steam turbine for use in gas turbine combined-cycle power plants. Combined-cycle power generation systems combine gas turbines and steam turbines to achieve high fuel efficiency as compared to conventional thermal power plants. The new facility is also much more economical than previous plants. The steam is then fed into the combined-cycle plant, increasing the steam turbine's power and creating extra megawatts of electricity, all without using any extra natural gas. In a triple combined cycle power generation system, an SOFC power generation system is placed before the GTCC system. Combustion (Gas) Turbines: Combustion turbine plants operate on the Brayton cycle. The power plant's The share of combined cycle power plant in the total electricity generation in Turkey amounts to two percent. GE Energy & Mitsubishi Heavy Industries Sign MOU to Co-Develop World's Most Advanced New Steam Turbine for Combined-Cycle Power Plants édité le 31/01/2009. Then the fuel is introduced and ignited to produce a high temperature, High-pressure steam from these boilers can also generate power with steam turbines, which is called a combined cycle (steam and combustion turbine operation). The working cycle of the power plant will involve both gas and steam turbines. The 60 hertz J-Series gas turbine achieves a rated power output of about 320 megawatts (MW) (ISO basis) and an unprecedented 460 MW in gas turbine combined-cycle (GTCC) power generation applications, in which heat recovery steam generators and steam turbines are also used.
