The agents which are currently being considered as
replacements for fire suppressant agent CF3Br are mostly
fluorinated hydrocarbons and perfluorinated alkanes.
This abstract describes measurements of the reduction in
burning rate of premixed methane-air flames with the
addition of the single carbon inhibitors CF4, CF3H,
CF2H2, and CF3I. Early studies of the inhibitory
effects of halogenated hydrocarbons on flames were
conducted in premixed systems. The premixed laminar
burning rate is a fundamental parameter describing the
overall reaction rate, heat release, and heat and mass
transport in a flame. In addition, the reduction in the
premixed flame burning rate is useful for understanding
the mechanism of chemical inhibition of fires since
diffusion flames often have a stabilization region which
is premixed, and good correlation has been found between
the reduction in burning rate and the concentration of
inhibitors found to extinguish diffusion flames.
Premixed flame burners have flow fields which are
relatively easily characterized, making interpretation
of the inhibitor's effect on the overall reaction rate
