Abstract
A power plant with a combustion chamber in which a fuel in burned in a fluidized bed of a particular material, comprises a storage container for the bed material which, upon a load reduction, is removed from the combustion chamber. The storage container is provided with a sieve or a grate which prevents slag lumps formed in the bed material from penetrating into a conduit for the return of the bed material to the combustion chamber. A tube projecting into the storage container forms the sieve.
