摘要： According to one or more embodiments, a chemical feed distributor may include a chemical feed inlet and a body. The chemical feed inlet may pass a chemical feed stream into the chemical feed distributor. The body may comprise one or more walls that may define an elongated chemical feed stream flow path and a plurality of chemical feed outlets. The plurality of chemical feed outlets may be spaced on the walls. The plurality of chemical feed outlets may be operable to pass the chemical feed stream out of the chemical feed distributor. The elongated chemical feed stream flow path may comprise an upstream fluid flow path portion and a downstream fluid flow path portion. The walls may be positioned such that the average cross-sectional area of the upstream fluid flow path portion is greater than the average cross-sectional area of the downstream fluid flow path portion.

摘要： The invention provides an apparatus which consists of two fluidized beds 1 and 2 separated by a vertical divides' 5. A positive displacement device such as an auger 3 moves the bed material from the reduction side to the combustion side of the device below the fluidization zone. The height of the two fluidized beds is equalized by movement of the bed material through a hole 4 In the vertical divider, from the high temperature side 1 (zone 1) to the tow temperature side 2 (zone 2). The bed material that moves through the hole 4 provides energy to drive reactions that may occur on the reduction side. Energy may also be provided to zone 2 by means of conductive and radiative heat transfer through the dividing wall 5. Energy is provided to zone 1 by means of an exothermic reaction, typically combustion of a fuel 13 using air 12.
