Abstract
A method and an apparatus for heating a carbonization drum is especially used for heating a carbonization drum for a low-temperature-carbonization combustion process. Heating gas heated in a heat exchanger is guided in a heating gas loop from the heat exchanger through the carbonization drum. A heat sink is provided for cooling the heating gas. In order to control an energy supply to the carbonization drum, the heating gas is guided back again at least partially and in a controlled fashion through a bypass line, in which the heat sink is disposed, to the heat exchanger, while bypassing the carbonization drum. The heating gas can also be delivered partially and in a controlled fashion through the heat sink to the carbonization drum. A distribution of the heating gas into a maximum of three paths is ensured by a configuration of lines and control devices.
