| Abstract: | Taking the licensed 600 MW power unit as an example,influence of opening different number of control valves on the unit performance is being analyzed,such as on the relative efficiency and efficient specific enthalpy drop of governing stage,the efficiency of high pressure cylinder,the power consumption of feed pump etc.Optimal mode for sliding pressure operation is obtained from above comparison.It is pointed out that for different types of power unit,different number of control valves should be open so as ... |
