Abstract:
The effectiveness of the iron compounds Fe(CO)5 and
ferrocene ((C5H5)2Fe, Fec) has been observed in premixed
Bunsen-type flames as well as in counterflow diffusion
flames. Recent work has extended such tests to
tetramethyltin (TMT, Sn(CH3)4) and
methylcyclopentadienylmanganese tricarbonyl (MMT,
C9H7MnO3), both of which are more effective than CF3Br,
but less so than Fe(CO)5. No tests with these agents,
however, have been done in flames more typical of fires.
The present work remedies this deficiency by presenting
results for addition of these highly effective agents to
cup-burner flames. Not only does the structure of cup
burner flames resemble that of fires, but there also
exists a large database of previous cup-burner
extinction results for comparison with the present data.
