- fluidized beds can also be operated so that upwardly discharged particles are deposited on a filter, cyclone or other suitable separator and returned to the fluidized bed.
- the fluidized beds can also be operated as a fluidized bed.
- a reactive component can be passed into the fluidized bed.
- the reactive component can be mixed with the carrier gas or fed separately.
- the supply of the carrier gas stream can take place via a corresponding gas-permeable bottom, for example made of sintered metal, plastic mesh, floors with screws or Conidurböden, via nozzles or tangential inlet openings in the lower part of the apparatus.
