Silica Fouling Fundamentals and Control by Magnetic and Ozonation Methods

在大多数热交换器中都会发生结垢，其相关的性能退化具有相当重要的经济意义。多年来，它一直困扰着工业，但人们对它的理解和解决仍然很少。该提案是目前NSF资助的研究的延续，在此期间获得了有趣的结果。建议的研究将包括溶解度和聚合的基础研究，盐离子对二氧化硅结垢附着物的影响，污垢热阻的瞬时测量，以及溶解度和二氧化硅结垢形成的分析建模。要研究的应用主题将包括减轻磁性装置和臭氧化的污染。

Fouling occurs in most heat exchangers and the associated degradation of performance is of considerable economical importance. It has plagued industry for years and remains poorly understood and resolved. The proposal is a continuation of current NSF funded research, during which interesting results have been obtained. The proposed research will include fundamental studies on solubility and polymerization, effect of salt ions on attachments of silica scale, transient measurement of fouling thermal resistance, and analytical modelling of solubility and silica scale formation. Applied topics to be investigated will include mitigation of fouling by magnetic devices and ozonation.
