Abstract: A feed device for a granular firing product for furnaces with a minimum capacity of 1 kW, includes a conveyor screw disposed in a pipe for conveying a granular firing product. A central screw axis pipe has an outer wall with a volution mounted thereon and with the conveyor screw disposed in the pipe so that it can rotate and which is at least a quarter of the pipe diameter. The screw pipe axis has a conical shape at its tip, where a circular grating with a central circular hole and air feed openings on the outer region of the grating are horizontally disposed. The central circular hole is smaller than the diameter of the conveyor screw and a conically expanding funnel-shaped wall is guided downwardly from its edge as a sliding wall for a firing product to be conveyed. The conically expanding funnel-shaped wall runs substantially parallel to the cone of the upper end of the screw axis.

Abstract: The invention relates to a wood pellet stove, comprising a feed device for automatically adding wood pellets in a metered manner from a pellet hopper belonging to the stove. Said pellet hopper having the feed device and a grate is accommodated in a lower, stationary stove part (20), which remains cold and does not become hot during operation. The combustion chamber having a chimney connection is accommodated in an upper stove part (21). The upper stove part (21) is supported on the lower stove part (20) by means of a turntable so that the upper stove part can be swiveled relative to the lower, stationary stove part (20). Thus, the combustion chamber and the viewing window can be swiveled in any desired direction as needed.
