How does fouling affect the performance of a heat exchanger?
It reduces the heat transfer and decreases the overall thermal efficiency of the unit. Fouling in heat exchangers causes gradual impairment of its performance leading to increased pumping power. In addition, if timely cleaning is not scheduled it leads to severe penalty on operating costs [1].
What is the fouling factor of a heat exchanger?
The fouling factor represents the theoretical resistance to heat flow due to a build-up of a layer of dirt or other fouling substance on the tube surfaces of the heat exchanger, but they are often overstated by the end user in an attempt to minimise the frequency of cleaning.
Why is the fouling effect in water-based heat exchangers especially higher at elevated temperatures?
Water can produce scaling from minerals such as calcium carbonate (CaCO3). Salts deposit on the heat exchanger surface increases with an increase in temperature. Similarly, biological growth can occur with an increase in temperature during food processing.
How does fouling affect heat transfer and pressure drop?
The buildup of fouling also reduces the cross-sectional area of the tubes or flow channels and increases the resistance of the fluid passing over the surface. These side effects combine to increase the pressure drop across the heat exchanger, reducing flow rates and aggravating the problem further.
