摘要

采用一种基于热力系统变工况的计算方法

对国产亚临界600MW汽轮机级组效率降低对汽缸相对内效率及机组热耗率的影响进行了分析计算

结论可为同型机组节能改造、小指标考核等提供依据。

Abstract

A calculation method based on varying operating condition in the thermodynamic system has been presented

analysis and calculation for influence of stage group efficiency reduction upon relative inner efficiency of the cylinder and economic efficiency of the home-made subcritical 600 MW steam turbine unit being carried out.The conclusion and recommendations proposed can provide basis for energy-saving retrofit and for small indices assessment etc.of similar type units.
