摘要
结合火电机组热力系统的节能改造的需要 ,提出了热力系统节能改造的基本原则 ;基于循环复合的概念 ,修改了传统回热作功比的定义并发现了回热作功比与再热机组热效率之间的关系 ,提出了新的汽机内效率计算模型。最后 ,利用回热作功比 。
In order to meet the need of improvement the thermal system of reheater's turbines, the principle is put forword in this paper. Base on the physical concepts, the rate of regeneration work is modefied and explained. A new calculating models are discussed in which the relation between the rete of regeneration work and efficiency of reheater's turbine are finded. In the last, the projects for improving thermal system of turbine are evaluated by the rate of regeneration work.
