Abstract

Bei einer Heizvorrichtung umfassend einen Brenner (3), einen Ascheraum (2), einen Auffangraum (4) für Flugasche, einer ersten Förderschnecke (9) und einer zweiten Förderschnecke (8), wobei der Brenner (3) mit stückeligem Brennstoff, insbesondere Pellets, beschickbar ist, und wobei der Brenner (3) im Bereich des Ascheraums (2) angeordnet ist, wobei der Auffangraum (4) durch eine Trennwand (5) vom angrenzenden Ascheraum (2) getrennt angeordnet ist, wobei die erste Förderschnecke (9) im Ascheraum (2) und die zweite Förderschnecke (8) im Auffangraum (4) angeordnet ist, wobei die erste Förderschnecke (9) und die zweite Förderschnecke (8) eine gemeinsame Schneckenwelle (13) aufweisen, und wobei die Trennwand (5) eine Durchführungsöffnung (14) für die Schneckenwelle (13) aufweist, wird zum Erzielen eines kompakten und platzsparenden Aufbaus, sowie zum Erzielen eines hohen Wirkungsgrades vorgeschlagen, dass die Heizvorrichtung eine Dichtklappe (11) aufweist zum, insbesondere unmittelbaren, Verschließen der Durchführungsöffnung (14), welche Dichtklappe (11) durch angeförderte Asche öffenbar ist.

Figure imgaf001
In a heating device comprising a burner (3), an ash compartment (2), a fly ash collecting space (4), a first conveyor screw (9) and a second conveyor screw (8), the burner (3) with particulate fuel, in particular pellets , and the burner (3) is arranged in the region of the ash compartment (2), the collection compartment (4) being separated from the adjacent ash compartment (2) by a partition wall (5), the first conveyor screw (9) in the ashtray (2) and the second screw conveyor (8) in the collecting space (4) is arranged, wherein the first screw conveyor (9) and the second screw conveyor (8) have a common screw shaft (13), and wherein the partition (5) a Through-opening (14) for the worm shaft (13) is proposed to achieve a compact and space-saving design, as well as to achieve a high efficiency that the heater has a sealing flap (11) for, in particular unmitte lbaren, closing the passage opening (14), which sealing flap (11) can be opened by subsidized ash.
