Unwanted Combustion Enhancement by Potential Halon Replacements: Thermodynamic Considerations

Abstract
It is desirable to replace Halon 1301, CF3Br, as the fire suppressant used in cargo bay fire suppression. Unfortunately, some candidate agents for replacing Halon 1301, in particular C2HF5, C3H2F3Br, C6F12O, were found to create greater pressure rise in an Federal Aviation Administration (FAA) qualification test simulating an exploding aerosol can, and hence failed the test. The present work describes the thermodynamic behavior of C2HF5, C3H2F3Br, and Halon 1301 in the FAA aerosol can test when added at varying concentrations. The pressure rise in previously published FAA experiments are predicted, and the reasons for the overpressure are discussed.Citation
