Abstract:
The existence of lean and rich concentration limits of the low-velocity regime of flame propagation was shown experimentally under filtration of a combustible gas mixture in narrow tubes. The values of the limits depend on the inner diameter of the tube. Experiments with an inhibitor affecting the concentration limits of combustion-wave propagation in tubes in a low-velocity regime showed that branching chain reactions occur in the filtration combustion wave and the concentrations of active centers thus exceed the equilibrium values. In the low-velocity regime, the surface of the narrow quartz tube slightly decreases the role of active centers in combustion-wave propagation.
Keywords:
filtration combustion of gases, chain reactions, inhibition, flame propagation limits, low-velocity regime.
