Current studies on stability and combustibility of marine fuel oil

摘要

Developing techniques to evaluate fuel stability and combustibility is essential to ensure the quality of marine fuel oil.Experimental research was performed to determine the combustion performance of marine fuel using the thermogravimetry-differential thermal Analysis (TG-DTA) and the fuel droplet combustion method an(l the fuel ignition Analyzer(FIA-100)The results made it possible to distinguish between normal fuel and fuels which caused combustion problems.Compatibility of fuel oils follows solubility theory. The solubility of asphaltene can be predicted by the Scatchard-Hildebrand equation. This paper describes how to apply the solubility theory to evaluate fuel stability of marine fuel oil.
