摘　　要： 通过汽轮机变工况计算及凝汽器的热力计算 ,分析了营口化纤厂自备电厂CC1 2型汽轮机低真空供热对汽轮机电功率、轴向推力、汽缸膨胀、凝汽器冷却管膨胀的影响 ,进而分析了CC1 2型汽轮机低真空供热的安全性和经济性 ,并对该汽轮机低真空供热的效益进行了计算及分析。该汽轮机经过 4个月的低真空供热运行 。 The influence of the low vacuum heat supply of CC12 type turbines in the Self Powered Plant, Yingkou Chemical Fiber Factory on the electric power, axial thrust, cylinder expansion, cooling tube expansion of the steam condenser of the turbine was analyzed with the calculations of the off design condition and the thermal performance of the condenser of the turbine. The safety and economy of the low vacuum heat supply of CC12 type turbine were analyzed, the efficiency of the low vacuum heat supply was calculated and analyzed. The calculation and analysis results were proved to be correct with four month operation.
