Numerical Study of the Inhibition f Premixed and Diffusion flames by Iron Pentacarbonyl

摘要

Iron pentacarbonyl (Fe(CO)_5) is an extremely efficient flame inhibitor, yet its inhibition mechanism has not been described. The flame-inhibition mechanism of Fe(CO)_5 in premixed and couterflow diffusion flames of methane, oxygen, and nitrogen is investigated. A gas-phase inhibition mechanism involving catalytic removal of H atoms by iron-containing species is presented.
