摘要
A device for drying and torrefaction of at least one carbon-containing material flow in a multiple-hearth furnace includes a drying zone, a torrefaction zone, a heat exchanger for heating the drying gas flow, the discharge point of the drying zone being connected via the heat exchanger to the infeed point of the drying zone; and a combustion assembly, wherein the discharge point of the torrefaction zone is connected via the combustion assembly and the heat exchanger to the infeed point of the torrefaction zone, wherein a torrefaction gas flow discharged via the discharge point of the torrefaction zone is combusted in the combustion assembly and the resulting exhaust gas is used in the heat exchanger to heat the drying gas flow and is fed to the torrefaction zone, wherein the drying zone and the torrefaction zone comprise two separate gas circulations.
