摘要：
A method of discharging heat from a particulate material in a bed (28) of a combustor (12) in the event of an operational disturbance in a PFBC power plant. Gas from the combustor (12) is cooled in a cooling circuit (69) connected to the combustor (12) and is returned to the combustor (12) where it is allowed to pass through the bed (28). A device for carrying out the method comprises a cooling circuit (69), connected to the combustor (12), with a cooler (72) and a compressor or fan (76) which effects gas circulation through the cooling circuit (69) and the combustor (12).
