Combustion kinetic modeling has long been expected to be, and is now becoming, a powerful tool for combustion engineering. In this article, fundamental aspects of the kinetic modeling will be introduced with a special focus on the technological prospects for clean and efficient combustion. Firstly, essential issues of the gas-phase thermodynamics will be described as it plays central roles in temperature variation and chemical equilibrium as well as the close relation to the statistical theory of chemical reaction rates. Secondly, the overview of the chain reactions, especially the branched chain reactions, will be discussed as behaviors of a system of reactions and thus a system of ordinary differential equations. Lastly the characteristics of the hydrocarbon oxidation as it shows NTC (negative-temperature coefficient) region and cool flame will be investigated in terms of the LTO (low-temperature oxidation) mechanism with the discussion of the possibility of controlling the cool flames.
