摘　　要：本文介绍了水钢锅炉利用热管换热器对高炉煤气进行加热。通过对提高高炉煤气进入锅炉炉膛内温度来提高燃烧效率，降低锅炉排烟温度，使二次能源得到充分利用。It is introduced that blast furnace coal gas into boiler is preheated by heat pipe exchanger in Shuigang. The combustion efficiency is improved with temperature increase of blast furnace coal gas into boiler furnace. The flue gas temperature decreases so that the second energy is fully utilized.

关 键 词：煤气温度 热管换热器 热效率 排烟温度
