Method and apparatus for combusting and/or gasifying a generally viscous liquid or a slurry wherein the liquid or slurry are atomized in a central atomization device within a burner housing the central atomization device using a portion of a gaseous oxidant introduced into the burner to atomize the liquid or slurry as it exits the atomization device.

[ What is claimed:] [1.] A burner for introducing an atomizing fluid and a black liquor into a high temperature high pressure gasification vessel comprising in combination:a generally cylindrical burner housing having a first end and a second end, said housing adapted to be mounted into an outer wall of said gasification vessel with said second end of said housing positioned to direct a flame longitudinally within said gasification vessel;means in said housing to direct a flow of gaseous oxidant from proximate a first end toward a second end of said housing;atomization means disposed along a longitudinal axis of said housing and extending from said first end of said housing to proximate said second end of said housing, said atomization means consisting of an outer generally cylindrical conduit having a first end proximate said first end of said housing and a second end defining a converging nozzle, an inner conduit disposed within said outer conduit and of a diameter to define a generally annular passage between said inner and outer conduits with an atomization tip on an end of said second conduit proximate said second end of said first conduit said atomization tip being of a diameter to engage an inner wall of said outer conduit said atomization tip having means in an outer surface to permit discrete streams of an atomization fluid to flow between said atomization tip and said inner wall of said inner conduit with a swirling motion, said atomization tip terminating in a converging surface generally complimentary in shape to an inner surface of said converging nozzle said converging surface of said atomization tip ending in a nozzle orifice in fluid communication with said inner conduit, said inner conduit adapted to conduct said black liquor from a first end of said burner to said nozzle end of said atomization means, whereby said atomized black liquor exits said atomization means in a swirling flow.
