Pre-determination of the Fouling and Cleanliness Factor of the Heat Exchanger

Heat exchanger degradation is a nonperiodic non stationary process, which depends upon the variation of parameters w.r.t time. The measurements are associated with gross errors, if they are not properly handled, they may lead to erroneous estimation and prediction of heat exchanger performance. The objective of this paper is to pre-determine the fouling factor and cleanliness factor obtained in the heat exchangers to avoid the degradation and capital cost losses obtained during the heat exchanging process. The performance factor of heat exchangers degrades with time due to scaling or fouling factor. In this paper we have monitored, predicted and diagnosed heat exchanger performance.
