Abstract
A device for cooling a fine-grained solid includes a fluidized bed cooler/heater in which the solid is fluidized with a fluidizing gas and thereby releases energy in the form of heat within the cooler/heater at least two cyclones which are connected in parallel. The cyclones are arranged such that after the fluidization of the solid the fluidizing gas passes through the cyclones so contained particles are removed.

A device for cooling a fine-grained solid, comprising:
- a fluidized bed cooler/heater in which the solid is fluidized with a fluidizing gas and thereby releases energy in the form of heat;
- and
- at least two cyclones connected in parallel and provided within the cooler/heater such that the at least two cyclones are located inside of the cooler/heater, whereby the cyclones are arranged such that after the fluidization of the solid the fluidizing gas passes through the at least two cyclones so contained particles are removed, wherein the at least two cyclones connected in parallel have a common outlet leg for withdrawing the particles from the fluidized bed cooler/heater and a sealing device adapted to seal the common outlet leg.
