What is Fouling Factor?

The water used in water-cooled condensers always contains a certain amount of minerals and other foreign materials, depending upon its source. These materials form deposits inside the condenser water tubes. This is called water fouling. The deposits insulate the tubes, reduce their heat transfer rate and restrict the water flow. The fouling factor is the reciprocal of heat transfer coefficient for the material of scale.

The following are the recommended fouling factors

1. For copper tubes used for R-12 and R-22 condensers, the fouling factor is 0.000 095 m2 s K/J.
2. For steel tubes used in ammonia condensers, the fouling factor is 0.000 18m2 s KIJ.
