DETONATION ARRESTOR WITH COOLING SECTION AND QUENCHING SECTION, AND METHOD OF COOLING AND QUENCHING A FLAME FRONT TRAVELLING IN A LINE CARRYING FLAMMABLE GAS ROBERT KARL RAJEWSKI ABSTRACT A detonation arrestor for a line carrying a combustible gas includes a cell housing having a portion that is directed to quenching a detonation front and a portion that is directed primarily to heat absorption so that the heat of a continuous or prolonged burn can be withstood. The quenching portion may be a porous quenching medium. The heat absorption section contains a large mass of metal with porous channels through or between them. An example is a plurality of closely spaced stacked plates, which may be helically wound or plane parallel plates. Crimped ribbon or other spacers may separate them. As an alternative to the quenching medium, the plates may extend long enough to allow flame fronts to be quenched between them. The detonation arrestor is symmetrical and may be placed in the flare line in either direction. If particulate quenching medium is used, a deflector ring encircles the interior of the cell housing and prevents flame fronts from flashing along the edge of the cell housing.
