国产N200MW机组蒸汽冷却器系统的经济性分析

Economic Analysis on the Steam Cooler System of the Domestic N200MW Generating Unit

本文运用等效热降理论,对国产N200MW机组的蒸汽冷却器系统进行了经济性论证。结果表明:№6加热器所用油汽如加装外置式蒸汽冷却器比现有的加热器更能充分地利用蒸汽的过热度,降低发电煤牦,提高机组的运行经济性。

This article gives an economic demonstration on the steam cooler system of the domestic N200MW generating unit by using the equivatent heat drop theory. The result illustrates if a outboard steam cooler is installed extra for the NO. 6 heater of the existing heater, the steam superheating degree will be used more completely, the generating coal com.suption will be lowered and the operation economy of the generating unit will be improved.
