Synergistic extinguishment characteristics of physical and chemical agents on buoyant liquid flames
This paper presents a comparative study of the flame structure before extinguishment of liquid heptane flames in a co-flowing stream of air in an apparatus simulating the NFPA standard 2001 cup-burner apparatus. Physical agents, N2 and CO2, and a chemical agent Halon 1301 were used as flame extinguishing agents. Results indicate that when the physical agents were mixed with chemical agents, the amount of the mixture needed for extinguishment is lower than the sum of the agents when they were individually used. This synergistic effect of physical and chemical agents has been investigated in terms of the thermochemical structure of the flame including temperature profiles, mass burning rates, and concentration of oxygen and carbon monoxide in the flame exhaust.
