【摘要】 近年随着国家能源产业政策的调整 ,将逐步淘汰能耗高的小型火电机组 ,而同时城市热网的负荷需求和热电厂供热能力的不足又十分突出 ,利用原有设备和管道系统 ,采用新技术对凝汽机组的供热改造将是及时有效的解决方案。所述供热改造方案 ,不仅采取措施提高了汽轮机通流部分效率和回热循环效率 ,解决了与原有设备的匹配问题 ,并且进行了试验研究和分析 ,对改造效果进行了技术经济评价更多还原

【Abstract】 Recently, accompany the adjustment of energy estate policy, our contry will weed out small condensing power satation. But city need more heat supply. This document discussed the method which not only improved the trube group efficiency and, but also resolved the problem that new equipment cooperated with old system. The document also give research and evaluation of the heat engine.更多还原
