摘要：With urgent requirements of high efficiency and low pollution of energy utilization, gas-steam combined cycle is widely used in power station.In this paper, based on gas turbine design condition, a triple pressure without reheat steam bottom cycle system is established and parameters matching between different pressure steam and reasonable design of bottom cycle are carried out.On this basis, the performance analysis of steam bottom cycle at all operating condition is conducted.As for vaporization problem at exit of the economizer at part-load condition, some of original parameters are designed again as one solution and the bottom cycle process is partly improved as another solution.
