Abstract

A combustion plant comprises a combustion chamber (10), which is arranged to contain a fluidised bed (12), formed by a bed material, for the combustion of a fuel. The combustion chamber (10) comprises a bottom structure (15), which is provided with a number of nozzles (16), which are provided in such a way that they extend upwardly from the bottom structure and are arranged to supply an oxygen-containing gas for the combustion of the fuel and the fluidization of the bed material. Said nozzles (16) have an elongated shape and comprise at least one first gas outlet opening (17) in an upper part of the nozzle. Moreover, said nozzles (16) comprise at least one second gas outlet opening (24) in a lower part of the nozzle (16) for supplying a limited amount of said gas to the bed material in order to cool the latter.
