Particle Measurements in Fe(CO)5-Inhibited Flames (NISTIR 6242)



M D. Rumminger, Gregory T. Linteris


Since iron pentacarbonyl (Fe(CO)5) is among the most efficient flame inhibitors ever identified, research on flame inhibition by Fe(CO5) was recently started at NIST with the goal of understanding its mechanism. Obtaining a detailed understanding of this super-effective chemical inhibitor will provide insights and approaches useful for development of the next generation of fire suppressants to replace the ozone-depleting suppressant CF3Br. Our approach has been to use simple laboratory burners (premixed Bunsen-type flames and counterflow diffusion flames) to obtain global, yet fundamental, information on the action of Fe(CO)5.
