A combustion burner includes an air supply case connected to an air supply mouth a position at a position on the air supply case from a rear end part to a tip portion thereof, which supplies air from air supply equipment; a nozzle body attached so as to cover a tip portion of the air supply case, and having a jet nozzle formed in a center part of the nozzle body; a fuel nozzle in the nozzle body so as to supply air from the air supply case through an air jet hole, placed between the tip perimeter part of the fuel nozzle and the jet nozzle, having a frusto-conically shaped fuel supply passage, and which supplies air from a tip portion thereof; a plurality of air guide holes provided between an outer circumferential portion of the fuel nozzle and the nozzle body so as to supply air from the air jet hole in a spiral pattern; a fuel supply support member in the fuel supply passage, which supplies fuel from at least two fuel supply holes in an opposite spiral pattern from the tip end of the fuel nozzle; and at least two fuel supply pipes, one end part of the fuel supply pipes being connected to the fuel supply holes, another end part thereof being connected to a fuel supply which supplies waste oil, heavy oil and the like; and a water supply, which supplies water, dirty water and the like. Water, air, and oil, including waste oil, heavy oil and the like are mixed as an emulsion at a top part of a nozzle and mixed fuel is burned at lower cost without dissociation of the emulsion. The combustion burner of the invention obviates the need for expensive equipment, including a mixer, heretofore conventionally required, and can be used independently of such mixing equipment.
