description abstractAiming to describe the heat transfer process of tubular heating furnace from the angle of energy quality, an exergy transfer model of tubular heating furnace was established to evaluate the energy consumption level of heat furnace. The model is based on the 1-N heat exchange chain theory, innovatively combined with the transfer evaluation index. The temperature distribution in the furnace chamber is calculated by the mathematical model of the zonal method, and then the reduction rate of the heat transfer density and the resistance rate of the heat transfer are calculated. The results show that the exergy potential of the radiant furnace tubes during the heat transfer of the heat furnace is large, and the influences of both the blackness of the furnace wall and the coefficient of convective heat transfer of the exergy transfer of the radiant furnace tubes under steady-state conditions are discussed in detail. With the increase in the blackness of the furnace wall, the exergy density of the flue gas side of the pipe wall increases significantly. With the decrease in the coefficient of convective heat transfer, the exergy density of the working medium side of the tube wall decreases significantly. The energy efficiency of the heat furnace can be improved by adjusting the two parameters in engineering.
