Dust particles can be removed from the dust collector 12, for example, via a side cyclone arranged outside the device 1, and it is likewise possible to guide these dust particles into the discharge chamber 17.
- return or return vanes 13 are provided which are substantially axially effective and convert the circumferentially oriented flow of the fluidizing agent into a static pressure and deliver the fluidizing agent to the superheater 6 for conditioning or heating.
- an outlet pipe 14 can be derived by the fluidizing agent.
- the return vanes 13 extend radially outward from the outlet tube 14 to the periphery of the superheater 6.
- Other fluidizing agent conditioning means may be provided to condition the same. In particular, cleaning devices must be provided so that the fan or the fan wheel is not damaged by impinging dust particles or the like.
- a circulating flow guide has the advantage that the particles in the fluidizing agent can be optimally separated via the additional swirl blades 11 and the dust separator 12.
- the unidirectional circulation direction of the fluidizing agent and the particle also facilitates the recirculation and conversion of the swirl impulse to a static pressure due to the curvature of the return vanes 13 having an opposite orientation relative to the curvature or inclination of the swirl and supplemental swirl vanes 9,11.
