<p>The present invention relates to a method and a device for maintaining a high gas temperature to the gas turbine in a PFBC power plant, wherein gas is fed out from a fluidized bed (2) in a combustor (1) which also includes tubes (3) for cooling the bed (2), said tubes (3) being completely or partially covered by the fluidized bed (2) in dependance on the degree of load. The method is characterized in that hot combustion gases are discharged from the combustor (1) via outlets (5a) arranged at higher levels or via outlets (6a) arranged at lower levels in dependence on the degree of partial load.</p> |
