Fluidized bed reactor

Abstract

Abstract A FLUID BED REACTOR GAS DISTRIBUTION GRID OF STEEL PLATE CONSTRUCTION HAVING AN UPPER PLATE AND A LOWER PLATE SPACED THEREFROM WHEREIN THE LOWER PLATE INCLUDES A RADIAL- LY OUTWARDLY EXTENDING PERIPHERAL RING PORTION CLAMPED BETWEEN THE REACTOR BASE PLATE AND WINDBOX GRID SUPPORT RING AND HAVING A FLOATING NON-HEAT CONDUCTIVE SEAL BETWEEN THE GRID RING PORTION AND REACTOR BASE PLATE SO AS TO NOT ONLY PROVIDE A THREE-WAY SEAL BETWEEN THE ATMOSPHERE, REACTOR BED CHAMBER AND WINDBOX, BUT TO ALSO ALLOW THE LOWER GRID PLATE TO EXPAND, AND THE UPPER GRID PLATE BEING PROVIDED WITH MEANS FOR ALLOWING IT TO EXPAND RELATIVE TO THE LOWER GRID PLATE AND CONNECTING GRID SIDE WALL, AND WHEREIN THE LOWER GRID PLATE IS IN DIRECT HEAT TRANSFER RELATION WITH THE GRID SUPPORT RING TO PROVIDE MEANS FOR TRANSFERRING HEAT FROM HIGH BED TEMPERATURE TO THE OUTER WINDBOX SHELL, AND THE EXTERIOR DIMENSION OF THE GRID BEING SUCH AS TO PROVIDE A CLEARANCE BETWEEN THE GRID SIDE WALL AND ADJACENT REACTOR REFRACTORY WHICH CLEARANCE IS LOOSELY PACKED WITH INSULATION MATERIAL TO FURTHER ASSIST THE SEAL AND TO PROTECT THE REACTOR BASE RING FROM THE DETRIMENTAL EFFECT OF HIGH BED TEMPERATURES.
