The paper deals with the problems of shell-and-tube heat exchangers operation taking into account the influence of scale and corrosion deposits on heat transfer efficiency. On the basis of numerical modeling performed in the ANSYS CFX program complex, research of various geometrical characteristics of heat exchangers, as well as deposit thicknesses on the heat transfer efficiency was carried out. The simulation results showed that the increase in fouling thickness worsens heat transfer in heat exchangers with large tube diameters, while in heat exchangers with small diameters the heat transfer fluid velocity increases, compensating for the additional thermal resistance. The influence of various parameters on the operation of heat exchanger equipment is evaluated and recommendations on optimization of its operation and frequency of cleaning are offered.
