ABSTRACT

Filtration combustion waves in H₂S/air mixtures are modeled in the present work within the one-dimensional approach taken into account multistep chemistry and separate energy equations for the gas and solid phases. The superadiabatic wave propagation is a complex phenomenon, and many factors that influence wave properties, in particular the heat loss rate, interfacial heat exchange or effective heat conductivity of the porous medium, must be accurately specified. We developed a numerical model to describe combustion wave characteristics in a coordinate system moving together with the wave front. The products of partial H₂S oxidation, H₂, and S₂ are dominant for ultra-rich superadiabatic combustion. The chemistry in the combustion wave is modeled, and species and temperatures profiles are predicted. We produced a database of hydrogen and sulfide conversion in a wide range of equivalence ratios and other process parameters.
