Partial oxidation process for slurries of solid fuel
A partial oxidation process including a burner is provided for introducing four separate feedstreams including a stream of gaseous material from the group free-oxygen containing gas, steam, recycle product gas, and hydrocarbon gas; a pumpable slurry of solid carbonaceous fuel in liquid phase e.g. coal-water; and two high velocity streams of free-oxygen containing gas into a free-flow partial oxidation gas generator for the production of synthesis gas, fuel gas, or reducing gas. The burner has a central conduit and three concentric annular passages. A central core of a gas selected from the group consisting of free-oxygen containing gas, steam, recycle product gas, and hydrocarbon gas surrounded by the slurry of solid carbonaceous fuel is discharged from the central conduit and first annular passage respectively and is impacted by two separate streams of free-oxygen containing gas passing through the second and outer annular passages. With this burner, at least one stream of high velocity free-oxygen containing gas is always available, even at turn-down, to provide atomization and intimate mixing of the slurry feed.
