    • According to a process for the combustion of organic substances, such as domestic or industrial waste and the like, in a fluidized incineration bed (1) at a mean combustion temperature of 800.degree. C., the flue gased emitted by the fluidized bed (1) are heated with the associated flue dust to a temperature of at least 900.degree. C., preferably 1000.degree. C. to 1200.degree. C., in a subsequent combustion zone (23), in order to destroy toxic substances are burnt. To this effect, the flue gases are introduced in the incinerating chamber of an industrial furnace, for example a steam generator (2) of a coal-operated power plant. By connecting in the gas supply line a fluidized bed (1) upstream of a steam generator (2) fired with coal, a substantial reduction in NOx formation is achieved.
