Аннотация
Upper concentration limits of flame propagation in H2—C3H8—air mixtures at elevated initial pressures are determined. It is revealed that the flame propagation area widens substantially with the initial pressure rise. It is found that the presence of hydrogen promotes combustion of rich propane—air mixtures at concentrations of propane that exceed its upper concentration limit. It is concluded that research results can be explained from consideration of features of chain branching reactions, which are responsible for hydrogen and hydrocarbons combustion in air.
