How does fouling factor affect heat transfer

How does fouling factor affect heat transfer?

   The scaling of heat exchangers is costly every year and can seriously affect the safety of production. The fouling of a heat exchanger refers to the solid matter layer that gradually accumulates on a solid surface when the heat exchanger is in contact with an unclean fluid. The main influences of scaling on heat exchange equipment: because the fouling layer has a very low thermal conductivity, which increases the heat transfer resistance and reduces the heat transfer efficiency of the heat exchange equipment.When the scale layer is formed on the surface of the heat exchange equipment, the flow area of the fluid passage in the heat exchange device will be reduced, resulting in an increase in the  fluid resistance as it flows through the device, thereby consuming more pump power and increasing production costs.
