Abstract

Some organometallic compounds of iron are two orders of magnitude more effective at volume fraction than CF₃Br in premixed flames, an order of magnitude more effective in counterflow diffusion flames. The condensation of active gas-phase iron-containing intermediates to particles is believed to be the cause of the loss of effectiveness. The present paper reviews previous work on gas-phase inhibition by iron compounds as well as the role of particles in Fe(CO)₅ inhibition of those flames. The understanding obtained from those simpler configurations is used to interpret new measurements of flame inhibition and particle formation in cup-burner flames of methane and air with iron, tin, manganese and bromine compounds added to the air stream.
