Abstract The Zeldovich-Li[nbar]an model, originally proposed by Zeldovich and analyzed asymptotically by Li[nbar]an, has recently been analyzed by Joulin et al. (1985) under a particular distinguished limit. The limit considered by Joulin et al. only has solutions with algebraically small concentrations of radicals in the neighborhood of a particular flame temperature. For flame temperatures above this, the concentration of radicals becomes 0(1) whereas for flame temperatures below the pivotal value the concentration of radicals become exponentially small. Joulin et al. do not discuss this aspect of the problem but it is demonstrated here. Flame structures with only algebraically small radical concentrations can be found for all reasonable flame temperatures under the limit of large activation energy and large heat release. Such a limit does not predict gross qualitative changes in the flame structure as the flame temperature crosses a pivotal value. This limit also predicts adiabatic flame speeds without...
