Abstract:The status and development trend of the ultra-supercritical coal-fired power generation technology are introduced.A scheme in which the steam turbine generator of the ultra-supercritical coal-fired generating units with double reheater are placed in high and low platform separately is presented.The technical feasibility of this scheme is discussed and the economic analysis is conducted.The results show that the scheme can reduce the initial investment of the units for 3.15%,and improve the total efficiency ...
Keywords:steam turbine generator  placement in high and low platform separately  ultra-supercritical unit  technical feasibility  economic analysis
