摘要
污垢系数的选取是换热器设计中非常重要的考虑因素,目前换热器设计中污垢系数的选取仍然不得不利用经验数据,造成采用的换热面积过大,引起一系列的运行和维护问题。笔者主要论述换热器中污垢的影响和如何考虑选取污垢系数在一个合理的范围。
Fouling factor is an important consideration in heat exchanger design,but currently it is selected based on experi- ences,which will result in excess heat exchanger area and a se- ries of operation and maintenance problems.This article ex- plains the impact of fouling factor on heat exchanger design and how to select a reasonable fouling resistance value.
