摘　　要：对增设外置蒸汽冷却器的350MW高加系统进行了全面分析计算。通过对比分析表明:增设外置蒸汽冷却器后,初投资增加约159.3万元,机组的热耗降低约10kJ/(kW·h),发电煤耗下降约0.363g/(kW·h)。增设外置蒸汽冷却器是提高机组运行经济性的一种有效方式。A comprehensive analysis and calculation of 350MW high-pressure system with external steam cooler is made.The comparative analysis shows that after adding an external steam cooler,the initial investment increase about 1593000 yuan,the heat rate of the unit reduced by 10KJ/(kW·h)and the gross coal consumption rate reduced by 0.363 g/(kW·h).It is an effective way for Adding an external steam cooler to improve the operation economy of the unit.

关 键 词：高加系统 蒸汽冷却器 热经济性
