Fouling and Scaling in Heat Exchanger #shorts #heatexchanger

The deposition of unwanted materials, such as scale, suspended solids, insoluble salts and even algae on the internal surfaces of the heat exchanger is called fouling.

The presence of these deposits represents a resistance to the fluid flow and heat transfer and therefore increase the pressure drop and reduces the efficiency of the heat exchanger. The degree of fouling varies considerably with physical properties of fluids being handled. In severe fouling conditions, the heat exchanger may become blocked and hence inoperable because of the back pressure.

Depending on the fouling deposits involved, they can lead to corrosion of the heat exchanger which can often be hidden by the fouling layer itself. This shortens the working life of the heat exchanger and can result in catastrophic failure.
