Sludge which is generated during the pulp production has to be treated. Thermal treatment of the sludge proved itself to be the most appropriate solution of the problem. A unit for this treatment in one large pulp and paper plant sludge incinerator had been built many years ago and was quite modern at that time. However, because of more sweeping environmental laws affecting the process industry, the unit needed a complete retrofit. A brief description of this unit (with a multiple hearth incinerator with a fluidisedbed combustion chamber) is supplemented by simplified flowsheet and basic characteristic data. First stage of retrofit considered mainly in installing a secondary combustion chamber and a contact cooler. The second stage of retrofit can be characterised as a %22waste-to-energy%22 one. An existing recuperative heat exchanger and the contact cooler were replaced by a new more efficient system of heat exchangers including ut" . . . "Hajn\u00FD, Zden\u011Bk" . . "4"^^ . .
