摘要
采用管内插入物增强锅炉烟管的放热系数是行之有效的手段,它不影响换热器的机械强度,便于拆装、检修和更换。在设计烟管锅炉,特别是改造烟管锅炉中,它是最有希望的强化传热方式之一。本文介绍了内插物强化传热实验装置的设计调试,及其一种内插件——螺旋线圈强化传热的实验研究和有关理论探讨。
The use of inserters inside boiler smoke tubes to increase the heat release coefficient of the smoke tubes is a practical and effective means having advantages of being easy to be removed, reinstalled, repaired and replaced without adverse effects on the mechanical strength of the heat exchanger. In designing, and especially in modifying a smoke-tube boiler, this is one of the most promising approaches to strengthen the heat transfer. Presented in this paper is a description of the design and testing of an experimental set-up for heat transfer strengthened by use of inserters inside tubes and an experimental study and related theoretical investigation on strengthened heat-transfer by inside-tube coil inserters.
