Abstract:
1. A feed injector system comprising: a plurality of annular channels substantially concentric about a longitudinal axis that define corresponding fluid flow paths that direct a flow of fluid substantially axially therethrough from a respective source to a reaction zone; and a plurality of swirl members extending into the fluid flow path defined in at least one of said plurality of annular channels, wherein at least one of said plurality of swirl members is movable axially within said at least one annular channel, wherein at least one of said plurality of swirl members comprises a plurality of blades aligned in a helical path spaced axially and circumferentially with respect to an adjacent swirl member in the helical path, and wherein at least one of said plurality of swirl members is configured to impart a first circumferential flow direction to fluid flowing through at least one of said plurality of annular channels, and at least one of said plurality of swirl members is configured to impart a second circumferential flow direction to fluid flowing through at least one of said plurality of annular channels, wherein the second circumferential flow direction is different than the first circumferential flow direction, and wherein a tangential velocity of the fluid is based on at least one of a pitch and a position of said plurality of swirl members.
