Abstract
A method and apparatus for production of cellulose based fuel pellets from wood logs includes steps of comminuting the wood logs to particulate wood material. The particulate material heat treated in a reactor and the pressure is reduced in a manner causing defibration of the particulate material. The material is pelletized using the softened lignin at least partially as a binder for the pellets. The comminution of the wood logs is effected as a single-step operation in which the wood logs are charged to a comminution station where at least one rotating drum provided with cutting teeth is arranged in a manner to fully comminute the wood logs. The particulate material may be fractioned and a selected size fraction used for the further treatment.
