摘　　要：本文通过十种灰样的大量试验, 研究了螺纹管内积灰的分布规律, 给出了适用泛围较广的积灰量计算公式,并计算分析了管内积灰对螺纹管传热性能的影响.Through a large number of tests on ten kinds of ash specimen, the ash deposition in tubes with twined ribs is studied, a calculation formula for ash depositin, with a relative wide range of applicability, is given. The influence of ash deposition on heat transfer is calculated and discussed.
