A fundamental property of interest in characterizing the
effectiveness of fire suppressants is the effect of
addition of inhibitors on the laminar flame speed of a
fuel as a function of pressure and temperature of the
unburned mixture. The effects of CF3H and C2F6 on the
laminar flame speed of mixtures of gaseous fuels and air
are currently being investigated in a laminar combustion
bomb (a constant volume combustion device amenable to
flame speed measurements at elevated and reduced
pressures). Preliminary results for CF3H-propane-air
mixtures are reported here. The data show little
reduction in the burning rate at elevated pressures for
addition of 1% CF3H but about 25% reduction in the
burning rate for 2% CF3H.
