Wood pellets or saw dust granules are concentrated and homogenized wood fuel made by pressing
dried and comminuted wooden waist like sawdust and cutter shavings. Also stem wood is used. During

the lignin. Pellets are neutral, renewable fuel. Its burning doesn’t spoil CO

Pellets have to be stored in a dry and ventilated room. Only premium wood pellets e.g. ENPlus-A1 can
be used in PV20a/30a burners. Table 2 provides an overview of the most important wood pellet
