A gas turbine plant having an ignition combustion chamber for applying heated gas to heat the fluidized bed material to ignition temperature. In starting up the plant, a starter motor is employed to rotate a turbine and thereby to cause a compressor to produce compressed air. Liquid or gaseous fuel is applied to the ignition combustion chamber and is ignited within the chamber to heat compressed air from the compressor. The compressed air is passed through the fluidized bed combustor to heat the bed material up to ignition temperature. During the start-up operation, bed material in the fluidized bed combustor is reduced to reduce the pressure requirements for the heated compressed air.
