  • Process for producing biocoal and plant therefor
    Patent number: 10934490
    Abstract: Disclosed is a process and plant for producing biocoal in which biogenous starting material located in retorts is pyrolyzed and the flammable pyrolysis gases formed by the pyrolyses are burned to generate hot flue gases. The retorts are introduced consecutively into at least one reactor chamber and by use of the flue gases the pyrolyses are performed therein. The retorts are at least largely closed toward entry of hot flue gases and the heating of the starting materials located in the retorts by the flue gasses is effected only indirectly via the heating of the retorts.
