NOVELTY - System comprises: a torrefaction reactor (215) configured to heat biomass to generate torrefied biomass; a stabilizer/conditioner (217) configured to receive the torrefied biomass from the torrefaction reactor, and to apply a liquid to the torrefied biomass to cool the torrefied biomass and increase moisture content of the torrefied biomass; and a densifier (220) configured to receive the torrefied biomass from the stabilizer/conditioner and to densify the torrefied biomass into pieces by the densifier.    USE - The system is useful for densifying renewable coal replacement fuel, which is useful in fuel-burning power plants, such as coal-burning power plants.    ADVANTAGE - The densification method increases the bulk density of the biomass resulting in reduced shipping costs, reduces hazardous dust, and/or aids in material handling by the consumers of the material, predominantly utilities wishing to replace coal with torrefied biomass.    DETAILED DESCRIPTION - System comprises: a torrefaction reactor (215) configured to heat biomass to generate torrefied biomass; a stabilizer/conditioner (217) configured to receive the torrefied biomass from the torrefaction reactor, and to apply a liquid to the torrefied biomass to cool the torrefied biomass and increase moisture content of the torrefied biomass; and a densifier (220) configured to receive the torrefied biomass from the stabilizer/conditioner and to densify the torrefied biomass into pieces having a second specific density greater than a first specific density of the torrefied biomass upon receipt of the torrefied biomass by the densifier. An INDEPENDENT CLAIM is included for a method comprising heating biomass to generate torrefied biomass, applying a liquid to the torrefied biomass to increase the moisture content of the biomass, and densifying the biomass into pieces.
