<p>A method is disclosed for heating the drying air of a biomass dryer, such as the drying air used in a wire belt conveyor. An essential feature of the invention is that the heating of the drying air takes place with the help of a water-glycol mixture or other equivalent nonfreezing medium flowing in an intermediate circuit, whereby a plant producing biodiesel obtains thermal energy for drying from another nearby-located industrial plant such as a pulp or paper mill.</p> |
