Title:
MANUFACTURE OF MIXED GAS AND BURNER THEREFOR
Document Type and Number:
Japanese Patent JPS5922991
Kind Code:
A
Abstract:
A high turndown de-slagging burner is provided for simultaneously introducing one or two mixed pairs of reactant feedstreams into a free-flow non-catalytic partial oxidation gas generator for the production of synthesis gas, fuel gas, or reducing gas by way of the central and/or annular sections of the burner, respectively. Each pair of feedstreams comprises a stream of free-oxygen containing gas with or without a temperature moderator and a pumpable liquid slurry stream of solid carbonaceous fuel, such as a coal-water slurry. Other hydrocarbonaceous fuels may be employed. The burner comprises four coaxial conduits (4,5,6,7) that are radially spaced to provide coaxial concentric annular passages (51,53,56,59). All of the conduits and annular passages are closed at the upstream ends and open at the downstream ends. Each pair of feedstreams is separately mixed together in a central or annular pre-mix chamber (67,71) located upstream from the face (2) of the burner. A water-cooled flat face-plate (8) is provided with separate passages for discharging air or soot-blowing or de-slagging media at the face of the burner.
