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).

Abstract: A compressor may include a casing defining a discharge cavity and a seal cavity. A rotary shaft may be disposed in the casing, and a shaft seal assembly may be disposed in the seal cavity and about the rotary shaft. An impeller may be coupled with and configured to be driven by the rotary shaft. A balance piston may be integral with the impeller and may define the discharge cavity and the seal cavity. A balance piston seal may be disposed about the balance piston such that the balance piston seal and the balance piston define a radial clearance therebetween. The radial clearance may be configured to provide fluid communication from the impeller to the discharge cavity. A heat shield may be disposed in the discharge cavity, and may be configured to prevent the conduction of heat from the discharge cavity to the seal cavity via the casing.
