    Biomass Drying and Dewatering for Clean Heat & Power

    the drying is more efficient in equipment designed especially for this purpose. If heat for the dryer is recovered from the boiler flue gas or gasifier—or from other waste heat sources—efficiency is further increased. For wood chips with a moisture content (M C) of 45%, the maximum boiler efficiency with standard equipment is about 74%
