ABSTRACT:
A flashback protection apparatus and method for suppressing deflagration of a deflagration-susceptible gas in a flow system in which the deflagration-susceptible gas is flowed. The method of the invention comprises monitoring the combustible gas to detect deflagration therein, and upon detection of a deflagration event producing a propagating flame front, opposedly directing at the propagating flame front a pressurized non-flammable gas in a sufficient volume and at a sufficient velocity to provide a non-flammable gas flow having a momentum at least opposedly equal to momentum of the propagating flame front and the associated accelerated combustible gas undergoing deflagration.
