本文分析了水－碳钢热管壁面温度调节与控制的原理。结合应用实例说明了由水－碳钢热管组成的热管换热器可以方便地调节冷热侧的换热面积以控制壁温，既适用于来流烟气温度较高的场合，又能控制换热器尾部壁温，有效地解决酸露点腐蚀的问题。 This paper analyzes the water - carbon steel heat pipe wall temperature regulation and control principles. The application example shows that the heat pipe heat exchanger composed of water-carbon steel heat pipe can conveniently adjust the heat exchange area on the cold and hot sides to control the wall temperature, which is suitable for the occasions where the incoming flue gas temperature is higher and the heat exchange Thermostat tail wall temperature, effectively solve the problem of acid dew point corrosion.
