Abstract

The burning of organic materials is integrated into the operation of a steam boiler or fluidized bed furnace. This is done by feeding the organic material (34) as a fuel current or the flue gases generated from the drying, degassing or burning of the organic material as a flue-gas current into the coal pulverizing mill (15), flue-gas back suction system or combustion chamber (22) of the steam boiler (1) and withdrawing the combustion products as a combusted-material current via the flue-gas purification unit and as an uncombusted-material current via the wet-ash removal facility, with the uncombusted material fed back as fuel current into the coal pulverizing mill, flue-gas back suction system or combustion chamber or burn-out grate of the steam boiler.
