Abstract
Abstract In a fluidization treatment reactor, the base of the treatment chamber is a grid perforated by cavities, and the bottoms of the cavities are respectively connected by syphons to fluidizing agent supply ducts which are connected to a common supply manifold. The syphons provide traps to collect any particulate material which falls through the cavities if the fluidization agent supply pressure falls.
