Abstract

The invention relates to a system (1) for feeding non- wood biomass comprising a feeding device (2) comprising a channel (3), a channel inlet (8), an outlet section (S2) comprising a channel outlet (9), and a feed screw (4). The system further comprises a charger (5) comprising a chamber (6), a chamber inlet (11), and a chamber outlet (12) adapted to be connected to the outlet section. The chamber comprises an expansion zone (7) for said non-wood biomass, which expansion zone extends between a first plane and a second plane, which first and second planes are located on opposite sides of the chamber inlet (11). The shortest diameter (D) of the expansion zone is equal to or above 2.7 times the shortest diameter (D) of the channel. The longest diameter (D) of the expansion zone is equal to or below 3.5 times the shortest diameter (D) of the channel.
