Popis: Uses an accelerated laboratory method to investigate the combustion process with drops of medium-sulfur residual fuel oils, and the effects of asphaltenes and additives on this process. Explains that one of the main goals in the use of medium-sulfur residual fuel oils in stationary and shipboard power plants is an increase in the completeness of combustion of these fuels, as this will result in smaller losses of fuel and lower levels of carbon deposit formation in boiler units and diesels. Finds that when additives are present, the fuel oils burn more intensely, owing to a change in the colloidal state of the asphaltenes; apparently, a reduction of the asphaltene particle size promotes their solubilization in the micellar structure of the fuel oil with the additive and promotes separation of the fuel oil into a ''light'' part and a coke residue. Points out that the more intense combustion also shows up in the greater brightness (higher temperature) of the flame, since when the additives are present, the height of the combustion curve on the recorder chart is greater; this reflects the catalytic effect on fuel hydrocarbon oxidation of the metals that are present in the additive (Fe, Mn, Cu, Al, etc.).
