Propane-Air Premixed combustible gas was lgnited. by the conventional current break syst-em lnside the open combustion chamber under the atomospheric preesure and the room temp-erature to measure the flame propagating speed and the burning speed, also to elucidate the history of the propagating flame behavior and wall effects to flame shape by using Ion Gap Method. and High Speed Schlieren Photography.<br/>
The results obtained show that the maximum flame propagating speed and maximum burning speed are approximately 292cm/sec and 36cm/sec at the mixture ratio 4.6%, respectively.The cellular flame structures can be observable in the rich mixture region, moreover, the cellular structures become finer, with increasing the mixture strength.
