The present invention is directed to water-in-oil type fuel oil emulsions which are particularly useful in firing boilers in ships, locomotives and industrial power plants. Furthermore, the invention is directed to aqueous particulate slurries dispersed in fuel oil. Specifically, the invention is directed to aqueous/oil slurries of combustible or non-combustible particulate having improved burning characteristics. Of specific interest are stable aqueous/oil slurries of coal dust. These emulsions and slurries are achieved through the use of a novel blend of cationic, nonionic and anionic surfactants to which the invention is also directed.
