摘　　要：结合目前低温空气预热器存在的问题和实际应用的结果 ,通过对光管、内螺纹管和热管的传热、流动阻力以及壁温 (低温腐蚀 )性能进行对比分析 ,阐述了内螺纹管和热管换热器作为空气预热器的优点 。Through comparison and analysis on the performance of heat transmission, flow resistance and wall temperature (sulfur attack) of light pipe, female fitting and heat pipe, the article combines the problems in the low temperature,air pre\|heater and actual result and represents the advantages that female fitting and heat pipe heat exchanger are used as air pre-heater. The article also declares the application conditions.
