本文通过模型计算和实验对于含尘烟气冲刷圆管和螺旋肋片管的管束换热器的流动和传热特性进行研究。结果表明，换热管束的形式对颗粒的传热强化作用具有明显的影响。颗粒对圆管的传热强化作用必须予以考虑，而对于螺旋肋片管则可忽略。
In this paper, the flow and heat transfer characteristics of the tube bundle heat exchanger with dust flue gas scouring tube and spiral finned tube were studied through model calculation and experiment. The results show that the form of heat exchange bundle has a significant effect on the heat transfer enhancement of particles. Particles on the tube heat transfer enhancement must be considered, while for the spiral finned tube can be ignored.
