The effect of the magnitude of activation energy on reaction rates has been examined. The conclusions suggest that a valid approximation to combustion mechanisms should be obtainable from a consideration of a single rate-controlling chain-branching and a single rate-controlling chain-breaking step. This concept has been applied in turn to homogeneous auto-ignition, ignition lags, limits of inflammability, flame propagation and burning velocities, resulting in a simple co-ordinating scheme. The formulae derived imply methods of identification of the rate-controlling processes from measurable flame properties.
