Title: Desulfurization of high sulfur fuels during combustion

Abstract: A simplified and continuous process for the removal of sulfur compounds and other impurities such as silicates from high sulfur coal or fuel oil during combustion in a molten salt bath containing a collector which reacts with the sulfur and other impurities. Sulfate and silicate impurities together with other by-products are removed by gravity separation from the molten salt bath as slurry from which the soluble salts may be regenerated and recycled continuously. Flue gases are recycled through the molten salt bath for sulfur-free emission to the atmosphere.
