摘　　要：通过对机组热效率、风温调节范围、送风机功率、系统投资、系统运行性能等方面进行技术经济对比,综合分析了锅炉暖风器系统与热风再循环系统各自的优越性,除设备投资以外,其他方面锅炉暖风器系统具有明显优势,尤其是机组节煤效益和送风机运行的节电效益最为突出。By comparing a sets' thermal efficiency, the air temperature's regulatory range, the forced fan's power requirement, the system's investment and the system's operational behavior, the paper comprehensively analyses the respective advantages of a boiler's air heater system and its hot air recirculation system. Except tor the investment required by the equipment, boiler air heater systems have their noticeable superiority, especially outstanding are the merits in respect to coal saving and energy of the forced air fan.
