Extinguishment characteristics of buoyant liquid and gas diffusion flames with physical and chemical agents

Babb, M. / Gollahalli, S.R. / Sliepcevich, C.M.

A comparative study of the extinguishment characteristics of liquid heptane and gaseous propane diffusion flames in a co-flowing stream of air in an apparatus simulating the NFPA standard 2001-cup burner apparatus is presented. A physical agent, carbon dioxide, and a chemical agent Halon 1301 were used as flame extinguishing agents. Results indicate that when the agents were premixed with air, the concentrations of CO₂ and Halon 1301 at extinction of propane flames were approximately the same as the corresponding values in heptane flames. Results are substantiated with the measurements of in-flame temperature profiles and exhaust gas composition/temperature measurements in the flames.
