A Study On Thermal Combustion Of Lean Methane–Air Mixtures: Simplified Reaction Mechanism And Kinetic Equations, Krzysztof Gosiewski, Anna Pawlaczyk, Krzysztof Warmuzinski, Manfred Jaschik

Krzysztof Gosiewski

Homogeneous combustion of lean methane–air mixtures occurs in both thermal and catalytic reverse-flow reactors. The modeling and design of such reactor requires a reliable and relatively simple kinetic model of the combustion. Although a number of detailed descriptions of the kinetics of homogeneous combustion are available in the literature (including those which take into account complex free-radical reactions), their practical usefulness is doubtful. In the present study a simple one- or two-stage model is proposed which directly describes global kinetics and neglects intermediates and radicals. Special attention is paid to the mechanism of the possible formation of carbon monoxide. The …
