Abstract

A device for generating additional energy in a power plant having a combustor (1) with a bed (4), to which air and fuel are intended to be supplied for combustion of the fuel therein while forming hot flue gases over the bed, and a gas turbine driven by these flue gases for generating energy, comprises means (21) arranged to supply additional fuel in the path (22) of said flue gases between said bed and the gas turbine for utilising excess oxygen available in the flue gases for combustion of this fuel there and members (23) arranged to supply a cooling medium to the flue gases in connection with said supply of additional fuel to the flue gas path for regulating the temperature of the flue gases to a desired level.
