摘　　要：高压加热器(高加)切除对机组热经济性有很大影响。以汽轮机功率方程和锅炉吸热量方程为基础,并将机组的整个回热系统视为一闭口热力系统,通过对其的热平衡分析,得到了高加切除对机组热经济性影响的计算模型。计算实例表明:该模型具有计算准确、适用性强的特点。High-pressure heaters （HPs） removal has a great influence on heat economy of unit. According to turbine power equation and boiler absorbed heat equation. By heat balance analysis of the whole regenerative system, which is regarded as a closed thermodynamic system, the calculation model on the influence of HPs removal on heat economy of unit is derived. The model discussed in the paper is proved to be possessed of character of accurate and more universal.
