Study on Deflagration Control Methods of Low Concentration Gas Extraction in Tube
Abstract：Water - mist, CO2 inert gas and dry powder are very effective on suppressing gas deflagration. With the increase of spray wa- ter - mist volume, the mixed CO2 concentration or sprayed dry powder quality are increased and flame propagation speed and peak over- pressure are reduced. The inbibitional effect of water - mist, CO2 inert gas and dry powder on deflagration is that the injection of water - mist, CO2 inert gas and dry powder can greatly decrease the concentrations of H, O and OH in chain reaction.
