This paper discusses the design and use of an apparatus for evaluating the effectiveness of liquid fire suppression agents as possible replacements for halon 1301. The apparatus consists of a porous cylindrical burner located in the test section of a vertical wind tunnel and a droplet generation system. Liquid droplets are injected into the flow stream and entrained upward toward the burner for evaluation. The suppression effectiveness is ranked based on the conditions at the transition from one mode of flame (enveloped) to the other (wake) established at the burner for a given fluid application rate. The apparatus is currently being used to test a variety of fluids.
