Conclusions

In the pulsating combustion of premixed mixtures the flame may be blown back from the combustion chamber into the mixing zone at velocities exceeding the flash-back velocity by more than an order. The chief factor in the determination of flame blow-back is the amplitude of the pressure pulsation, whose value depends on the combustion chamber dimensions, flow velocity, the temperature and composition of the mixture, and the resistance of the combustion chamber outlet system.
