Abstract
A power plant designed to burn fuel in a bed of fluidizable particulate material contained in a combustion chamber includes a tubular discharge device for bed material or dust separated from combustion gases leaving the combustion chamber. The tubular discharge device is designed as a cooler which is cooled by combustion air flowing into the combustion chamber and is utilized for pre-heating the plant upon start-up from a cold state. At least a part of the tubular discharge device, is electrically insulated from parts located upstream and downstream and from supporting structural members and forms an electrical heating unit. Upon start-up, this unit is connected to a current source for heating the air fed to the combustion chamber and downstream parts of the plant.
