Feeder

Apparatus for feeding of solid material, preferably solid fuels in a space (26) limited by a substantially plane bottom plate (10) forming a bottom surface (10'), around the bottom surface (10') arranged side walls (12, 14, 16) forming limiting surfaces (12', 14', 16') and an opening (20) in said space (26), the lower edge of said opening (20) lying in substantially the same plane as said bottom surface (10'), transporting means (30) arranged adjacent to said bottom surface (10'), which transporting means (30) extend through the limiting surface (16') opposite the opening (20), and drive means (38) arranged outside said limiting surfaces (12', 14', 16') and attached to said transporting means (30) in order to obtain a reciprocating movement of said transporting means (30) in a direction to and from said opening (20), characterized in that said transporting means (30) comprises a number of transporting rods (32) arranged substantially parallel with each other and substantially parallel with said bottom surface (10') and that the ends of the pusher rods during the reciprocating movement are located within the bottom surface, whereby the ends of the pusher rods will push the solid matter in the feeding direction during the forward movement.
