Systematic studies were carried out to investigate the explosion characteristics and morphology of the multicomponent explosive gas mixture CH3OH-NH3-air.It was found that the explosive limit of concentration of the gas mixture(CH3OH∶NH3=1∶1.1) was 12.85%—45.25%.There were only two explosion morphologies for the explosive gas mixture.One is cool flame,and the other is deflagration.Furthermore,strong detonation was not observed during the explosion experiments.N2 and steam did have some inert effect on the e...
