A combustion apparatus is fitted to the top of an oil burner having a single nozzle for the simultaneous introduction of oil and water by means of compressed air. The apparatus includes a combustion chamber defined by an inner vessel open at both ends with one end being fitted to the burner. An outer vessel is co-axially mounted on the inner vessel with both ends being secured to the corresponding ends of the inner vessel to form a preheating chamber between the inner and outer vessels. The inner vessel is provided with a plurality of holes and a baffle is located within the pre-heating chamber in overlying relation with respect to the holes. Pressurized air is introduced into the heating chamber, around the baffle, and through the holes into the interior of the vessel to compress the flame of the water-oil fuel emulsion forcing it to swirl and remain in the vessel so that the combustion takes place at a temperature between 700.degree. and 1,000.degree. C.
A method for the combustion of a water-oil emulsion fuel having at least a water content of about forty percent comprising simultaneously and separately supplying water, oil and compressed air to a nozzle having a single outlet for mixture of said water and oil in said nozzle, jetting the water-oil emulsion fuel by means of said compressed air from said nozzle into a combustion chamber defined by an inner vessel attached to the nozzle, preheating compressed secondary air in a pre-heating chamber located between said inner vessel and an outer vessel and introducing said preheated compressed air into the combustion chamber through a plurality of apertures in said inner vessel to compress the flame of the jetted water-oil emulsion fuel and force it to swirl and remain in the combustion chamber for combustion at a temperature of 700.degree. to 1000.degree. C. thereby causing the micro-explosion of the water particles and at the same time the pyrolysis of the water-oil emulsion fuel.
