Fouling Factors in Heat Exchangers - HRS Heat Exchangers

Jul 20, 2018· Chemical fouling: when chemical changes within the fluid cause a fouling layer to be deposited onto the tube surface. A common example of this phenomenon is scaling in a kettle or boiler caused by hardness salts depositing onto the heating elements as the solubility of the salts reduce with increasing temperature.
