Number 6 fuel oil was heated, sprayed, and burned in an enclosure using a small commercial oil burner. Samples of residues that emerged from the flame were collected at various locations outside the flame and observed by a scanning electron microscope. Porous cenospheres, larger globules (of size 80 μm to 200 μm) that resemble soap bubbles formed from the very viscous liquid residue, and unburned oil drops were the types of particle collected. Qualitative relationships of the morphology of these particles to the temperature history to which they were subjected were made.
