The National Institute of Standards and Technology has
been investigating the potential of fire-extinguishing
agents that act solely by the extraction of heat from a
flame zone, i.e., thermal agents, to serve as
replacements for halons. Both detailed chemical-kinetic
modeling and experimental characterization have been
used to better understand the behavior of thermal agents
in extinguishing fires. Most of our earlier work, some
of which was discussed during the 1999 and 2000 Halon
Options Technical Working Conferences, has focused on
methane as a fuel. In order to better understand fuel
effects, the studies have been extended to flames fueled
by propane. During this presentation we will summarize
the experimental and detailed chemical-kinetic modeling
results for extinguishment of propane flames by thermal
agents and compare the findings with those reported
earlier using methane. In this paper, experimental
extinguishment measurements and detailed
chemical-kinetic modeling investigations are extended to
propane diffusion flames. The results are compared with
earlier findings for methane flames in order to better
understand the role of fuel variations in flame
