摘要
首先对汽轮机相对内效率的概念进行了讨论 ,然后从汽轮机基本原理出发 ,推导出一种计算汽轮机各缸相对内效率变化对整机相对内效率影响的计算模型 。
The concept of relative internal efficiency of steam turbine is discussed firstly. Then based the basic principle of steam turbine, this paper gives the mathematics models that can be used to calculate the effect of the relative internal efficiency of cylinders on efficiency of steam turbine. The models provide efficient means for diagnosis of thermal economy and prediction benefit of improving steam path of steam turbine.
