Abstract

It is a now well-established fact that chlorofluorohydrocarbons, once emitted to the atmosphere, can lead to ozone depletion in the stratosphere due to their long atmospheric life times. When looking for new candidates for replacing the chlorofluorohydrocarbons (CFC) as refrigerants partly fluorinated hydrocarbons (HFC) and mixtures of these have been proposed. These substances are said not to participate in ozone degradation and - hydrogen being only partly substituted - show reduced atmospheric life time. Components with higher hydrogen content, however, tend to be combustible at atmospheric conditions. To prevent this to occur, mixtures made up of HFC have come to life as promising candidates. In some earlier papers, flammability limits and minimum ignition energies have been reported for pure and mixed HFC [l-41. All these mixtures, however, imply only partly fluorinated candidates. Therefore, it would be interesting to investigate the flammabilitybehavior of a fully fluorinated compound (FC) mixed with a nonhalogenated compound and compare it to the above-mentioned. In some recent papers, mixtures including a FC have been discussed as a possible candidate for refrigeration application [5,6]. In this paper, we report about measured flammability limits for blends (octafluoropropane + propane, R 218 + R 290) and (octafluoropropane + methane, R 218 + R 50) in mixture with air.
