Title: BURNER FOR THE COMBUSTION OF MATERIAL FOR COMBUSTION IN THE FORM OF A COMMINUTED WOOD PRODUCT, IN PARTICULAR OF FINE MATERIAL
Abstract:
The invention relates to a burner for the combustion of material for combustion (18) in the form of a comminuted wood product, in particular of fine material (18), having (a) a material-for-combustion feed (20) for the feed of the material for combustion (18), (b) a screw conveyor (24) for conveying the material for combustion (18), (c) a combustion region (46), wherein the screw conveyor (24) is arranged to convey the material for combustion (18) from the material-for-combustion feed (20) to the combustion region (46), (d) an air feed (26) for feeding air (50) to the combustion region (46) and (e) a burner mouth (42) for discharging combustion gases (52) out of the combustion region (46). According to the invention, a tamping region (32) is provided which is formed, in the material flow direction (M) of the material for combustion (18), downstream of the material-for-combustion feed (20) and upstream of the combustion region (46), wherein a conveying screw (28) of the screw conveyor (24) and the tamping region (32) are designed for compressing the material for combustion (18) in the tamping region (32).
