V型翅强化换热采暖炉

分析了家用采暖炉及其系统的运行特点和要求。由热平衡方程出发，讨论了提高家用采暖炉热性能和降低成本的途径。对Ｖ型翅强化换热家用采暖炉的特点进行了阐述并做了热性能试验，将其结果与上部带有环形烟道的家用炉和Ｓ型翅强化换热家用炉在性能和成本方面进行了比较。计算了Ｖ型翅和直翅的对流换热系数。

DOMESTIC HEATING STOVE ENHAMCING HEAT TRAMSFER WITH V-SHAPE FINS

Domestic coal stoves generally are served both as auxiliary heat sources for passive houses as well as cooking devices in rural China.In this paper,based on heat balance analysis of a typical domestic coal stove,a cost effective stove design,especially a water jacket with fin in T pattern,is presented.The calculation results of performance and cost for water jacket with fins in T pattern are compared with that in S pattern.
