摘　　要：熔鈦炉余热锅炉达到使用年限后,内部热管失效教量多,需对原熔盐炉余热锅炉进行重新设计。通过对熔盐炉余热锅炉进行设计改造,合理布里各受热面,将烟气溫度降至烟气露点溫度以上,最大限度的回收该部分热能,取得了良好的经济效益和社会效益。After the waste heat boiler of the molten salt furnace reaches the service life,because of the large number of internal heat pipe failures,the original waste heat boiler of molten salt furnace needs to be redesigned.Through the design and transformation of the waste heat boiler of the molten salt furnace,the heating surfaces are reasonably arranged,the flue gas temperature is reduced to above the flue gas dew point temperature,and the part of the heat energy is recovered to the maximum extent,and good economic and social benefits are obtained.
