Steam turbine, producing more power. The most attractive means of utilising a biomass gasifier for power generation is to integrate the gasification process into a gas turbine combined cycle power plant. The Korean companies are building the two power plants for The delivery from Siemens includes a total of six SGT5-4000F gas turbines, six SST5-3000 steam turbines, and six SGen5-2000H generators. Low grade waste heat from the steam generator exhaust can be used within the plant, to dry the biomass fuel before it is fed into the gasifier or to preheat the fuel before entry into the gasifier reactor vessel. Comprising 23 gas turbines and seven steam turbines, the installed power generation capacity of the DUBAL Power Plant is 2,350 MW (at 30˚C). 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. Combined-Cycle Gas & Steam Turbine Power Plants, 3rd Edition: Feature. The company previously supplied 40 7EA gas turbines for the PP10 site. The gas turbines are fuelled primarily by natural gas and, thanks to the cogeneration and combined cycle configuration of the utility, approximately 36.8% of the power generated at DUBAL is fuel-free. GE is to provide ten of its SC series steam turbines specifically for the PP10 combined cycle expansion. The company will provide six F-class gas turbines for the Ras Djinet and Ain Arnat 2000 MW combined cycle power plants (CCPP) in Algeria for Daewoo E&C Co., Ltd and Hyundai Engineering Co.
