Abstract:
A horizontal moving bed reactor for heat treating particulate material comprising:a housing having inlet means for admitting therein the particulate material to be heat treated and outlet means for discharging the heat treated material;at least one tray disposed horizontally inside said housing between said inlet and outlet means and having a support surface for supporting a bed of said particulate material;heating means for heating said bed of particulate material on said support surface; anda conveyor system for moving said bed of particulate material while being heated along a predetermined direction on said support surface, said conveyor system including a plurality of horizontally spaced-apart rake members extending across said support surface transversely of said predetermined direction and each having a plurality of spaced-apart fingers in sliding contact with said support surface, and means for moving said rake members to displace with said fingers said particulate material along said predetermined direction, the fingers of any one of said rake members being misaligned with the fingers of any other of said rake members and being spaced relative to one another such that said fingers rake across substantially the entire support surface of said tray and constantly stir said particulate material while displacing same, thereby constantly exposing fresh surfaces of said particulate material to heat and increasing heat transfer in said bed.
