Abstract
A method and apparatus for the debonding and sand core removal of sand cores from cast parts, the heat treating of metal parts and the removal of organic contamination from metal parts, which is utilizing a fluid bed furnace having an improved fluidizing gas distributor which discharges fluidized gas in a downward direction away from the parts in the fluidized bed.
Claims7
A fluid bed reactor or furnace for heat-treating parts comprising a fluid bed reactor or furnace including at least one door for entry and exit of the parts and a gas phase distributor including a gas phase piping array discharging into a fluid bed of granular solids through a plurality of tuyeres coupled to and mounted beneath the piping array in a perpendicular orientation such that the granular solids below the piping array are fluidized thereby causing the fluidizing gas in the piping array to indirectly heat the fluidized bed prior to entering the fluidized bed through the tuyeres, wherein the top of the piping array is adapted with a screen.
