摘要: 凝汽器冷却面积是凝汽器选型的一个重要指标,对汽轮机运行真空有重要影响。以某电厂1 000 MW汽轮机组为例,分析计算凝汽器冷却面积增容对汽轮机冷端系统性能的影响,为该电厂新机组筹建工作提供了合理建议,并形成了一套凝汽器冷却面积变化对汽轮机冷端系统性能影响的综合分析方法。对大型汽轮机组来说,发现冷端系统存在问题后应进行冷端系统性能诊断分析,查找主要原因并有针对性的解决问题。

关键词: 1 000 MW汽轮机, 冷端系统, 凝汽器, 冷却面积, 增容

Abstract: Being as an important indicator for condenser type selection, the cooling surface area has significant effects on condenser operating vacuum. Taking a 1 000-MW steam turbine unit for example, the effects of condenser cooling surface expansion on the cold end performance are analyzed and calculated, reasonable suggestions on new units preparation for the power plant are provided, and the comprehensive analytical methodology is formed for this issue. For large steam turbine units, the diagnostic analysis should be conducted to determine the major causes and solutions when problems existing in the cold end system are figured out.

Key words: 1 000-MW turbine, cold end system, conedenser, cooling surface area, expansion
