摘要
再热减温水对机组经济性的影响很大。引入了循环效率系数的概念,对机组正常循环和再热减温水循环进行分析。这种方法可以在常规热力试验中使用,直接反映出某一工况下的减温水影响,且计算时不需要使用机组排汽焓。给出了使用的示例,并将此方法与热平衡计算的方法进行了比较。
The reheater desuperheating water exerts great influence on the unit economy. The concept of cycle efficiency coefficient is introduced to analyze the normal cycle of the unit and the reheater desuperheating water cycle. The method can be used in conventional thermal performance test, and can directly reflect the influence of desuperheating water. In addition, the exhaust enthalpy of the unit is not needed for calculation. A case example is given, and the method is compared with the heat balance method.
