High turn down burner for partial oxidation of slurries of solid fuel

摘要: 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 and hydrocarbon gas; pumpable slurry solid carbonaceous fuel in liquid phase e.g. coal-water; two high velocity streams gas into free-flow partial oxidation generator production synthesis or reducing gas. The has central conduit three concentric annular passages. core selected consisting surrounded by discharged first passage respectively impacted passing through second outer With this burner, at least one always available, even turn-down, to provide atomization intimate mixing feed.
