【摘要】 分析了汽轮机高、中压缸之间的蒸汽泄漏原因及其对汽轮机中压缸效率的影响。阐述了应用温度推理法进行泄漏测试的原理及方法,并给出了该测试方法的应用实例。此方法为测量高、中压缸之间蒸汽泄漏流量提供了一种思路,也为分析同类型机组热耗率变化原因提供了又一分析手段。更多还原

【Abstract】 The causes for the steam leakage between high and mediunm pressure cylinders in turbine,and the effect of this leakage on the efficiency of a medium pressure cylinder in a turbine are analysed.The theory behind,and the ways and means of determining leakage by temperature reasoning are discussed with a typical example given.This method provides another way of thinking for determination of steam leakage flow between high and medinm pressure cylinders,and another means of analysis for causes of heat rate for similar power generators.更多还原
