Patent ID: 8795602

Claim:
A feed injector system, comprising: an inner oxidizer channel configured to convey a first oxidizer stream to a reaction zone; a solid fuel channel extending around the inner oxidizer channel, wherein the solid fuel channel is configured to convey a solid fuel feed to the reaction zone; a liquid reactant or moderator channel extending around the inner oxidizer channel, wherein the liquid reactant channel is configured to convey a liquid reactant or moderator to the reaction zone; and a second oxidizer channel extending around the solid fuel channel, the liquid reactant or moderator channel, or a combination thereof, wherein the second oxidizer channel is configured to convey a second oxidizer stream to the reaction zone; wherein the liquid reactant or moderator channel and the second oxidizer channel each comprises a diverging tip configured to direct the second oxidizer stream and the liquid reactant radially outward from an axis of the inner channel.
