    • Method for igniting a combustion chamber with a fluidized bed upon start-up and a power plant for carrying out the method. According to the invention bed material, which is heated to the ignition temperature of a start-up fuel, is transferred from a storage container (40) to the combustion chamber (8), and fuel is supplied to the bed (14). The air flow through the nozzles (13) of the combustion chamber bottom (12) are reduced during said transfer of bed material and are increased again when the fuel is supplied. The power plant according to the invention is equipped with means for temporarily by-passing the nozzles (13) of the combustion chamber during the transfer of the hot bed material to the combustion chamber. For preheating and storing the bed material to be supplied to the combustion chamber, an isolated container (40) is provided, which is separated from the combustion chamber and positioned at a level above the bottom of the combustion chamber. In a plant with a combustion chamber (8) enclosed in a pressure vessel (10), a connection with a valve (55) for by-passing the air flow may be provided between the space (11) in the pressure vessel and the freeboard (18) of the combustion chamber (8) for reducing the airflow through the bed. Further, control means (38, 80) are provided for carrying out the necessary operations of valves, and the like, during the start-up operation.
