WATER COOLED BURNER NOZZLE FOR SOLVENT REFINED COAL Abstract of the Disclosure A burner nozzle for solvent refined coal (SRC) is disclosed having means for removing heat which is adequate to maintain the exterior temperature of the burner nozzle below the level at which deposition of SRC residue has been observed. A specific embodiment comprises a water jacket about a tubular nozzle, the fuel outlet end being tapered t an edge at the fuel outlet end. The water jacket is provided with circumferential channels for circulating cooling fluid in a circuitous path around the nozzle. The channels are sized so that maximum flow velocity, and therefore maximum convective heat transfer, is maintained a the tapered edge.
