Abstract

A fluid distribution system ( 208 ) is provided for a reactor vessel ( 200 ) defining a reaction chamber ( 202 ). The fluid distribution system ( 208 ) may include a radial distribution component ( 224 ) positionable within the reaction chamber ( 202 ) and adjacent a vessel inlet ( 212 ) at an end portion of the reactor vessel ( 200 ). The radial distribution component ( 224 ) may include one or more annular distribution conduits ( 230 ) configured to receive a fluid mixture provided to the reactor vessel ( 200 ). The fluid distribution system ( 208 ) may also include an axial distribution component ( 226 ) positionable within the reaction chamber ( 202 ) to extend from the radial distribution component ( 224 ) along a longitudinal axis of the reactor vessel ( 200 ). The axial distribution component ( 230 ) may include a plurality of helical conduits ( 236 ) fluidly coupled with the one or more annular distribution conduits ( 230 ) and configured to receive the fluid mixture from the one or more annular distribution conduits ( 230 ) and to disperse the fuel mixture uniformly within the reaction chamber ( 202 ).
