Abstract

A new simple method has been developed to measure the fouling factor inside a removed condenser tube. The principle of this method is to detect the temperature increase of the outer tube surface due to fouling inside the tube, where the condensation heat flux on the outer tube surface is substituted by thermal radiant heating. Equations for evaluating the fouling factor are presented.Tests have been performed by using several alminum brass tubes and titanium tubes which were removed from a few actual power condensers. Accuracy of the present method is estimated to be at most 1×10^-5m²·K/W of the fouling factor.
