Mathematical modeling of the area of tubular gas heater in the condensing mode of work

Flow and heat exchange for the tubular gas heaters with regard to the phenomenon of condensation of water vapors from the gas-air mixture, which moves in the tubular part of the heater under cooling of the gas-air mixture are analyzed. Equations of mathematical model which describe the processes of motion and heat exchange of gas-air mixture and condensate inside the radiating tube are compiled. The possibility of using the developed mathematical model for calculation of the parameters of the flow and heat exchange of the heaters is indicated.
