A flow distribution system for the plenum chamber (12) of a gas- liquid-solids fluidised bed reactor includes a baffled nozzle device (16) containing at least two baffle plates (30, 32, 34) for mixing and uniform flow distribution of gas-liquid- materials in the lower portion of the plenum (12), used in combination with a distribution grid (18) to effect a uniform flow distribution of the gas/liquid mixture upwards into a fluidised bed (20). A sparger can be provided in the plenum above the baffled nozzle for feeding additional gas-liquid mixture into the reactor. A fluid recycle pipe (24) may extend through the plenum chamber. <IMAGE> |
