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.
