Abstract

The present invention relates to a combustion chamber and a method for combustion in a fluidised bed. The combustion chamber (1) is arranged to house a fluidised bed and comprises a plurality of heat exchanger tubes (20). The combustion chamber is arranged for sub-stoichiometric combustion in a first zone (21) in the bed (4) and arranged for stoichiometric or over-stoichiometric combustion in a second zone (22). The combustion chamber is arranged to allow the mixing of partially non-combusted gases from the first zone (21) and gas with a surplus of oxygen from the second zone (22) in a space above the bed (4).
