本文通过计算实例，讨论了变负荷、变过量空气系数及积灰引起的烟温变化对热管换热器最高允许工作温度的影响、对最后几排热管低温腐蚀的影响以及对热管换热器流动阻力的影响，对热管换热器的安全使用和设计有一定的意义。
In this paper, the influence of variable load, variable air coefficient and flue gas temperature caused by fouling on the maximum allowable working temperature of heat pipe heat exchanger, the influence on the low temperature corrosion of the last few heat pipes and the heat transfer to heat pipe heat exchanger The effect of resistance has some significance on the safe use and design of heat pipe heat exchangers.
