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. The inside of the conveyor pipe is provided with a rough surface, preferably longitudinal ribs, so that the firing product is supported and does not rotate with the conveyor screw.
