Research on Influencing Factors of Methane/Air Combustion in the Ring Porous Medium Burner
In this paper, we focuses on combustion characteristics of the mixed gas of methane/air in the ring porous medium burner using numerical simulating method. The influencing factors of combustion, such as different methane/air ratio, the velocity of flow and heat loss of internal and external wall, are discussed, and it is shown that the ring porous medium burners have some advantages different from straight or rectangular porous media burners. Due to annular asymmetric structure, the temperature distribution of ring porous media burners are more uniform, and are no unfavorable phenomena such as the local high temperature and the hot spots. The simulation results for annular porous medium provides important theoretical basis for the development of new porous medium burners.
