• The Fluidized Bed Air Distribution Nozzle is designed to prevent particle buildup in the plenum through two main features: downward-pointing orifices and long narrow orifices that are too small for most materials to pass through.
• A deflected plate air flow system prevents buildup on the bottom of the bed.
• The nozzle allows for easy installation with bolt-on tips, facilitating quick replacement during maintenance.
• The product is cast, offering a quality solution at a low cost.
• It is suitable for both new installations and retrofits.
• The design is patent pending, and custom flow options are available.

The document provides flow rates and dimensions for different nozzle numbers and standpipe sizes. The flow rates are given in SCFM per nozzle at various PSI levels in the plenum. For example, the FB5 nozzle fits a 3/4" Sch 40 standpipe and has a K Factor of 2.24, with flow rates ranging from 3.2 SCFM at 2 psi to 5.9 SCFM at 7 psi. Larger nozzles like the FB22 fit a 1" Sch 40 standpipe and have a K Factor of 9.85, with flow rates from 13.9 SCFM at 2 psi to 26.1 SCFM at 7 psi.
