Orimulsion{reg_sign} is a commercial fuel that has been marketed by PDVSA Bitor, for several years now. The original formulation was internally named Orimulsion{reg_sign} 100 (0100 for short). A second-generation commercial formulation was introduced to the market in 1998. This one is internally called Orimulsion{reg_sign} 400 (O400). This second-generation emulsion has proven to outperform the O100 in almost every aspect in a power plant, be it handling, firing or ash characteristics. This paper compares the physiochemical characteristics of the two ashes from several angles: Elemental and chemical compound composition, morphology, melting point, fouling characteristics and SO{sub 3} formation, pointing out their differences and the relationship between firing conditions and ash characteristics and emissions. Several analytical techniques were used to generate the results presented here, like: Scanning electron microscopy, x-ray diffraction, high temperature heating microscope, as well as results obtained at a dedicated bench scale facility to measure SO{sub 3} formation. The data obtained in this facility indicates that the O400 ash produces much lower levels of SO{sub 3} than the O100 ash. The results presented in this paper clearly indicate the improved ash characteristics of O400 when compared to O100 ash.
