This paper introduces a woody biomass heat energy system built for heat supply to a large-scale mushroom production farm in Iwate prefecture in Japan. The characteristic feature of this system is to use cheap waste wood bark with high water content as the raw material, supplying hot water and steam from biomass boilers for heating the mushroom cultivation houses. During the period when the heat demand of the cultivation house decreases, it is possible to produce high calorific value dry wood fuel from raw wet biomass utilizing boiler surplus heat. This dry wood fuel is stored on site and can be flexibly used within the plant as needed. It is also possible to deliver the stored dry wood fuel to other local boilers or cogeneration facilities in the surrounding area as fuel.
