换热表面污垢热阻影响因素的评价研究
Evaluation Studies of Influencing Factors on the Fouling Resistance of Heat Transfer Surface
摘要
Abstract
Considering the complexity and uncertainty of fouling deposition on heat transfer surface, it is an important research direction to assess the weight of influencing factors. Therefore, the grey relational analysis was applied to analyze and evaluate three influencing factors including quality of cooling water, operating conditions of the heat exchanger and heating surface structure in this paper. Results show that among six kinds of water quality parameters influencing the fouling deposition on heat transfer surface, the most significant factor is the alkalinity, the next is Ca2+, and then electrical conductivity, Cl-, turbidity and dissolved oxygen in order. Among the operating condition parameters, the inlet temperature of cooling water affecting fouling deposition is more serious than the inlet velocity does. Then the number of threads has a great effect on fouling deposition on the surface of ribbed tubes.关键词
