FLAME ARRESTOR DESIGN REQUIREMENTS FOR PROLONGED EXPOSURE TO METHANE/AIR, BUTANE/AIR AND GASOLINE/AIR FLAMES

Tests were performed in order to extend the empirical basis for evaluating the design of flame arrestors to the case of prolonged exposure to a stabilized flame for periods up to 30 minutes. Both parallel plate arrestors and crimped ribbon arrestors, whose dimensions of passageway diameter and length had been shown to be marginal for arresting moving methane/air and butane/air flames were tested. The results of the tests demonstrated that the design criteria (maximum D sub 4) to withstand prolonged exposure to a stabilized flame are slightly more stringent than the criteria for quenching or arresting a moving flame.
