摘要：In this paper, the influence of steam leakage of the control valve in bypass system on unit operating economy is analysed. Through quantitative analysis, the formulas for calculating the influence of the steam leakage of control valves in high-pressure, medium-pressure and low-pressure bypass systems on the parameters of unit work and heat absorption are obtained. In the end, combined with the design data, the thermal economy of 1000MW double reheat unit is analyzed in view of the internal leakage of control valve in high-pressure, medium-pressure and low-pressure bypass system.
