The technology that will be Since the output temperature of combustion gas turbines is high enough to produce good quality steam, modern, high efficiency plants use a combined cycle that adds a steam boiler and turbine to achieve an over all thermal efficiency of nearly 60%. Tokyo, December 13, 2011 - Mitsubishi Heavy Industries, Ltd. That is quite a bit higher than many people expect for coal fired power generation and is within the range of estimates for new nuclear power plant capacity. 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. Steam turbine, producing more power. The estimated time for the project is For this project, Abengoa has subcontracted Mitsubishi Power Systems Americas to supply the power block equipment which involves the gas turbine, the steam turbine and the heat recovery steam generator. 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. Now, the alternative is to build combined-cycle plants. With these plants, natural gas fuel goes into a gas turbine, but the waste heat is captured and used to power a steam turbine. Simple gas-fired turbines handle ramping up and ramping down better. Abengoa will be responsible for the engineering, design and construction of the combined cycle power plant under the engineering, procurement and construction (EPC) "turnkey" system.
