摘　　要：基于某超超临界660 MW燃煤火电机组低温省煤器系统,采用试验和热力计算进行节能效果评价,试验依据高精度的ASME PTC性能考核试验标准,理论计算采用等效焓降理论,结果表明热力计算与试验测量得到的节能量基本一致。等效焓降法结合性能试验,可以快速高效地研究机组各种热力状态下低温省煤器的热力特性,为机组经济运行和节能优化提供指导建议。Performance test and thermal analysis were conducted to evaluate the efficiency of a low- temperature economizer in typical 660 MW ultra supercritical coal-fired unit according to ASME PTC performance test code and using equivalent enthalpy drop theory, respectively. Combined the performance test with thermal calculation based on equivalent enthalpy drop theory, the thermal performance of the low- temperature economizer can be quickly and efficiently studied under various thermal conditions, which therefore may serve as a reference for economic operation, energy-saving and optimization of the unit.
