The Preparation and Combustion of Coal-Oil Mixtures

This paper describes a series of tests that involved incorporating a coal cleaning step, namely oil agglomeration as part of a procedure to prepare COM (coal-oil mixture). The combustion characteristics of the COM were improved by introducing 7–8 percent water. A large fraction of the ash particles from this COM were found to melt during combustion. Most of these molten particles contained vanadium, which was concentrated on their surfaces.
