摘要
通过对蒸汽在汽轮机中的做功分析,讨论了汽轮机汽缸相对内效率变化对机组热经济性的影响,提出汽缸效率变化热经济性分析计算模型,改变了传统热力学方法分析带来的复杂性,为汽轮机在线节能诊断提供了简单实用的计算工具。
Based on the theory of equivalent enthalpy,the influence of cylinder relative efficiency changing on unit heat economics is discussed and the thermal economics analysis models of cylinder relative efficiency changing are put forward,converting the com-plex analysis on account of using conservative thermodynamic method.The easy and practical computing tools are provided for on-line energy-saving diagnosis of turbine.
