ABSTRACT:
A method for heating a low temperature carbonization drum includes generating a low temperature carbonization gas in the drum; combusting a partial flow of the low temperature carbonization gas for generating a heating gas; conducting the heating gas in a heating gas circuit; preheating the cooled heating gas flowing out of the drum; and then returning a controllable partial flow of the cooled heating gas to the drum while re-admixing the controllable partial flow with the heating gas. A device for heating the low temperature carbonization drum includes a heating gas circuit having an inflow line and an outflow line connected to the drum generating low temperature carbonization gas; the heating gas circuit having a combustion chamber for receiving a partial flow of the low temperature carbonization gas from the drum and generating a heating gas to be delivered to the drum; and the heating gas circuit having a heat exchanger connected upstream of the combustion chamber for preheating the heating gas being cooled in the drum. A low temperature carbonization/combustion plant includes a combustion chamber of a combustion system receiving a remaining flow of the low temperature carbonization gas generated in the drum. The combustion system produces steam to be supplied to the heat exchanger.
