摘要
介绍了齿型螺旋翅片管束灰污系数试验研究的原理、试验系统及所采用的试验研究方法；将所得的试验结果与类似结构的整体型螺旋翅片管束及光管管束灰污系数相比较；得出了适用于工程实际的齿型螺旋翅片管束灰污系数计算公式．
The principle, system and investigation mehtod for experimentally determining contamination factor of helically segmental finned tube bank with gas-solid tWO phase fluid are introduced in the paper. ACcording to the investigation a formula for calculating contamination factors of the researched helically segmented finned tube bank is obtained.
