摘要

以一台 2 0 0MW双背压凝汽式汽轮机组为对象

采用分析其相对于单背压凝汽式汽轮机组功率增益变化的方法

分析了双背压汽轮机组变工况运行时主要工作参数对机组热效率的影响。指出为了取得最大经济效益及保证机组安全

在运行时应根据冷却水温度及凝汽器蒸汽负荷的变化对冷却水流量作相应调整或对机组负荷作相应限制。

Abstract

A 200MW condensing turbine wnit with different pressures in its two condensers is taken as an example to show the influence on the unit thermal economics by the main parameters during non-design operating condition. As a result it is pointed out that to obtain the economical gain and reliability of the unit

the quality of cooling water or the unit load have to be regulated according to the temperature of cooling water and the steam load of condens ors
