ABSTRACT:
A device for tearing-up and stoking straw into a burner unit. A reciprocating slide is provided under a magazine shaft for straw bales, the slide having mutually staggered teeth on its upper side in a forward part of the slide and elongated fins extending in the direction of movement of the slide in a rear part. The part closest to the stoking channel constitutes a piston means for the conveyance and compression of comminuted straw. The straw is torn-up during the initial advance movement of the slide towards the channel because the teeth are in engagement with the bottom of the lowermost bale, whereas the bale is upheld by the teeth and the fins during the return movement of the slide. The piston means ensures that the shredded straw is pushed into a stoking channel for the combustion chamber of a boiler. Very compressed straw bales are thereby very uniformly comminuted and compressed before being fed into a burner unit.
