Abstract: The present application discloses a continuous process for the preparation of fuel pellets, said process comprising the steps of a) feeding a feedstock to a torrefaction and partial pyrolysis step at a temperature in the range from 250° C. to 500° C., whereby a solid char and volatile fraction are obtained, said volatile fraction comprising a tar fraction; b) directing the evolved volatile fraction as counter current stream relative to the stream of the feedstock, and at least partially condensing the volatile fraction on the incoming feedstock so as to obtain a tar-rich fraction combined with the incoming feedstock; and c) pelletization of the combined solid char/tar-rich fraction so as to obtain said fuel pellets. Novel fuel pellets are also disclosed.

Novel fuel pellets are also disclosed.

Abstract: This invention relates to a boiler (1) drying, igniting and combusting refuse and producing steam (2, 2a) by heat exchange with flue gases (3). Said boiler (1) comprises a reactor (16) with firing a secondary fuel (18) for generating a less-corrosive gas flow (6) and an end superheater (8) located in the flow (6) of said less-corrosive gas. Said reactor (16) could be a sintering reactor, a rotary kiln, a fluidised bed or a spouted bed. This provides for an increased lifetime of the end superheater and makes the boiler provide a high and efficient electrical power output.
