摘　　要：基于热量分析法和[火用]分析法,分析研究某600 MW亚临界燃煤锅炉的给水温度、排烟温度对[火用]效率的影响。结果表明:降低排烟温度或提高给水温度,有利于提高锅炉[火用]效率,可为类似燃煤锅炉节能诊断提供参考。For a 600 MW subcritical coal-fired boiler, based on the thermal analysis method and the exergy analysis method, the influence of the feedwater temperature and the exhaust gas temperature on the exergy efficiency was analyzed and researched. Results show that, the exergy efficiency of the boiler can be improved by reducing the exhaust gas temperature or increasing the feedwater temperature. This may serve as a reference for energy-saving diagnosis of similar coal-fired boilers.
