Experimental study the fire-extinguishing effectiveness of 1-bromo-3,3,3-trifluoropropeneitrogen mixture

摘要

The search for a new fire-extinguishing agent with all the desirable properties of Halon 1301 has not been successful. We have pursued the development of 1-bromo-3,3,3-trifluoropropene (BTP), which has a very low extinguishing concentration, but with its high boiling point is not a suitable replacement for Halon 1301.However, mixture of BTP in an inert gas could produce fire-extinguishing agents with many of the desirable properties of Halon 1301.The fire suppression effectiveness of BTPitrogen mixtures was studied. The results show that addition of small amount of BTP in nitrogen reduces the extinguishing concentration of nitrogen considerably, with BTPitrogen mixtures suppressant showing strong synergistic interactions at low concentrations of BTP.
