摘　　要：本文讨论了汽轮机低真空供热热负荷、变工况计算、热化系数、热网供回水温度等问题。提出对居民小区，最佳热化系数为０．５３—０，５５．而且与热网供回水温度的确定无关，可供工程设计时参考。This peper discusses the issues concerning the computation of steam turbine low-vacuum heat supplythermal loads, off-design performance, thermification factors,heat supply network feeding and re turn water temperstures,etc. The author Proposed that the optimum thermification factor should be0.53-0. 55 irrespective of the network feedins and return water temperatures,which can be taken asa reference value for engineering designs.
