The effects of flow of methane-air gas on its explosion were investigated by using steel pipes of 102-385 mm diameters and 10-30m lengths. The results obtained are as follows.
The flow of methane-air gas has an effect on flame speed in case of the closed end ignition (the other end is open): the flame speed increases with the increase of flow speed in the range of 0-0.7m/s and takes nearly constant, maximum speed in the range of over than 0.7m/s, which is about twice than flame speed in the case of explosion of stationary methane-air gas. It may be said turbulent explosion takes place in pipe explosion as well as turbulent combustion in chamber combustion.
