- Abstract
- 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.
