Tiivistelmä
Torrefaction is one of the pretreatment technologies to enhance the fuel characteristics
of biomass. The efficient and continuous operation of a torrefaction reactor, in the
commercial scale, demands a secure biomass supply, in addition to adequate source of
heat. Biorefinery plants or biomass-fuelled steam power plants have the potential to
integrate with the torrefaction reactor to exchange heat and mass, using available
infrastructure and energy sources. The technical feasibility of this integration is
examined in this study. A new model for the torrefaction process is introduced and
verified by the available experimental data. The torrefaction model is then integrated in
different steam power plants to simulate possible mass and energy exchange between
the reactor and the plants. The performance of the integrated plant is investigated for
different configurations and the results are compared.
