摘要：
As a crucial application of heat exchange technology to process industries, a compact counterflow combustor filled with porous media has been newly proposed to realize self-sustaining combustion of lean fuel mixtures. In the present study, combustion enhancement is based on effective heat recirculation through porous medium between burnt gas and unburnt mixture. Numerical calculations have been conducted using an analytical model consisting of energy equations for the gas phase and porous medium. Assuming a one-step Arrhenius-type reaction, the basic characteristics of the present combustor have been qualitatively investigated. In particular, by systematically varying the flow velocity, the combustor length and the channel height, the dependences of the minimum heating value required for self-sustaining combustion on these parameters were discussed.
