To contribute making an index about the safety of woody pellet in large amount storage, the mechanism of spontaneous ignition of woody pellet was cleared by a survey from literatures and hearing results and the demonstration method was devised on the basis of its mechanism. When the moisture content in woody pellets is raised, the fermentation heat is generated. If this heat is stored in woody pellet storage layer, the additional heat is generated by natural oxidation. The ignition is occurred by continuation of oxidation heating. By the fundamental experiment with 4 kinds of woody pellets, it was cleared that woody pellet absorbed moisture. With the judgment from the water activity, the fermentation would be generated in the case that the moisture content of woody pellet would be over 15%. When the temperature of storage atmosphere was about 65 degrees, the generation of heat by natural oxidation was confirmed.
