Abstract:
A nozzle system for a fluidized bed including a pipe for insertion through an air distributor plate in the fluidized bed and extending up through a refractory material on the air distributor plate. A shaft is received in the pipe and has a washer and a collar which supports the shaft on the distal end of the pipe. A cap includes a top surface supported by a skirt, defining a protected annular exhaust space between the shaft and the cap skirt. Spaced discreet supports extend inwardly from the cap skirt supporting and centering the cap on the shaft.
