Claims5
A fluidized bed reactor comprising:
- a furnace containing a bed of particulate material including fuel through which air is passed in a manner to fluidize the particulate material;
- a vessel extending to the side of said furnace;
- an enclosed duct extending from said furnace to said vessel for connecting said furnace to said vessel;
- a plurality of nozzles extending through the side walls of said duct into the interior of said duct and directed in a substantially horizontal direction towards said vessel for introducing air into said duct in a direction towards said vessel to transfer a quantity of said material from said furnace to said vessel;
- means for passing air in said vessel to fluidize said material in said vessel and to entrain some of said material in said vessel;
- and
- means for connecting said vessel to said furnace for permitting the flow of said entrained material in said vessel back to said furnace.
