Abstract

The combustion conditions are extended and used C2H4 as fuel in addition to H2, to study the behaviour of chromium and iron oxide nanoparticles in diffusion flames that are seeded with precursors of the metals. Both Cr2O3 and Fe2O3 nanoparticles form early in the flame and then convert to gas phase species with different metal oxidation states later in the flame. The gas phase species turn into stable products further downstream in the flame, whose metal oxidation state depending on temperature, fuel type and other conditions. The results are correlated with previous studies of particle toxicity and a parallel study on OH generation of iron oxide nanoparticles. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
