  • SYSTEM AND METHOD FOR DENSIFICATION OF RENEWABLE COAL REPLACEMENT FUEL
    Publication number: 20130263499
    Abstract: A method may include heating biomass to generate torrefied biomass. The method may also include applying a liquid to the torrefied biomass in order to cool the torrefied biomass and increase moisture content of the torrefied biomass. The method may further include densifying the torrefied biomass into pieces having a second specific density greater than a first specific density of the torrefied biomass prior to densification.
