Abstract
The fire extinguishing ability of 1-bromo-1-propane/nitrogen (the molecular formula of 1-bromo-1-propane: CH 3–CH 2CH 2Br) and 1-methoxynonafluorobutane/nitrogen gas mixtures (the molecular formula of 1-methoxynonafluorobutane: CF 3CF 2CF 2CF 2OCH 3) as total flooding agents were evaluated by a cup burner method. It was shown that addition of small amounts of 1-bromo-1-propane and 1-methoxynonafluorobutane to nitrogen can enhance the extinguishing ability of the inert gas by 47.1 and 31.5%, respectively, and the relative of the extinguishing concentration to the concentration of 1-bromo-1-propane or 1-methoxynonafluorobutane in the flooding agents is: Y=5.18866+26.72165 e −X/11.07715 or Y=5.96301+23.59368 e −X/22.46021 . Meanwhile, an arrangement for mixing organic compounds with inert gases (N 2) before applying to fire was proposed.
