Abstract: The authors in this article have analyzed theoretical and empirical studies in the field of technologies of deep utilization of heat from exhaust gases. Various methods for determining the heat transfer coefficient during the process of using surface-type condensation heat exchangers are considered. The dependence of the heat transfer coefficient on various values of the velocity of the outgoing combustion products and the density of irrigation of the outer surface of the heat exchanger with condensate of water vapor from the flue gases is also considered. In the part of the calculations, the check was made for the convergence of the obtained values of the heat transfer coefficients according to the empirical formulas proposed for calculation with the values obtained using the formulas of the classical theory of heat transfer. Based on the results of computational and analytical studies, the authors proposed a conclusion about the advisability of using the above empirical dependencies in the design of condensing heat exchangers utilizing the heat of flue gases.
Keywords: combustion products, ribbed surface, condensation heat exchanger, heat transfer coefficient.
