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.
A device for tearing up and stoking straw into a combustion chamber, comprising an essentially vertical magazine shaft for straw bales, an essentially horizontal slide means located below and in communication with said shaft, said slide means including means for linear reciprocating motion from a first position vertically below the shaft to a second position into a stoking channel for conveyance of shredded straw and back again, the slide means including tooth means having single upward-facing elements mounted on the slide means, the tooth means being mutually staggered in the direction of movement of the slide means, and including first retaining means at a lower edge of the shaft closest to the stoking channel in the shape of stops projecting down towards the slide means and located such that the tooth means can pass between the stops.
