The high-pressure steam (typically 900 F at 800 psig) generated by the HRSG was sent to a separate steam turbine in the co-gen facility, acting as a pressure reducing station. Combined – Cycle Gas & Steam Turbine Power Plants – 2nd edition (August 1999). 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). 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. On Wednesday, Siemens opened a new 450,000-unit gas turbine production facility in Charlotte, N.C., next to its existing steam turbine generator plant. The power plant's The share of combined cycle power plant in the total electricity generation in Turkey amounts to two percent. Combined cycle plants have both a gas turbine fired by natural gas, and a steam boiler and steam turbine which use the hot exhaust gas from the gas turbine to produce electricity. Earlier this year, General Electric announced a new 510-megawatt combined-cycle power plant that claims fuel efficiency of up to 61 percent. The objective for this course is to present the main features of the Gas Turbine Combined Cycle, as employed for Power Generation, and Co-Generation (process steam of gas to industry). In a triple combined cycle power generation system, an SOFC power generation system is placed before the GTCC system. The new plant will employ Siemens H-class combined cycle gas and steam turbine technology and will be designed as a single-shaft plant with gas turbine, generator and steam turbine all arranged on a single shaft. 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. This configuration (gas turbine-generator-steam turbine) was known as Steam Turbine And Gas (STAG). The formal opening of the plant comes as international players jockey to produce the most efficient gas turbines and combined-cycle natural gas power plants possible. General Electric is hoping declining interest in coal sparks demand for their new combined cycle natural gas power plants, which can ramp up more quickly and idle at a lower generation rate than other systems, meaning they are Like other combined cycle plants, GE's new models generate electricity through turbines powered by burning natural gas, then the waste heat is collected and used to create steam which turns another turbine to generate more electricity.

The majority of power plants in use today use Combined Cycle Gas Turbine (CCGT) technology, so-called because a gas turbine is used to produce electricity in combination with a bottoming water-steam cycle. One of the most famous combined-cycle (CC) installations was a plant located in Futsu, Chiba prefecture in Japan. The combined cycle plant will have a heat recovery steam generator to collect the exhaust heat from the gas turbine and make steam.
