Abstract: The study of the influence of the degree of contamination of low-temperature heating surfaces on the intensity of convective heat transfer during the burning of non-design fuel based on computer modeling has been carried out.The results of the analysis showed that the amount of deposits varies depending on the temperature of the heat carriers in the air heater.A new method for calculating the thermophysical parameters of the heat transfer process has been developed on the basis of the ANSYS software package, which makes it possible to obtain a complete description of complex heat transfer processes in the boiler air heater.In the developed computational three-dimensional thermophysical model of a recuperative tubular air heater, there is no tube wall; the created thermal resistance of the wall is taken into account by introducing the coefficient of effective thermal conductivity of the flue gas flow.
