- Abstract
- Halogenated fire extinguishing agents such as CF₃Br decompose in flames to form hydrogen halides such as HF and HBr and other toxic and corrosive products. Possible replacements for halon 1301 are required in significantly higher concentrations to extinguish fires; consequently, the post combustion gases in the inhibited flames may have higher concentrations of these undesirable species. Previous experiments and analyses have been preformed to understand the phenomena important for HF production in inhibited propane-air diffusion flames. These tests have suggested that, for diffusion flames, both the rate of agent transport to the reaction zone and the chemical kinetic rates influence the formation of HF. In order to more clearly separate the importance of these processes and study HF formation in a more tractable configuration, the methods previously applied to diffusion flames are now extended in the present work to premixed flames.
