Abstract

Feststoff-Brennvorrichtung, bei der das Risiko der dauerhaften Ablagerung von Verbrennungsrückständen an den Wärmetauscherelementen stark verringert ist trotz einfachem und kostengünstigem Aufbau der Brennvorrichtung, mit Wärmetauscher zur Wärmeübertragung an einen FlüssigkeitsKreislauf, mit einem Brennrost zum Auflegen eines festen Brennstoffes, insbesondere Holz, einer Rauchgas-Abführung vom Hauptbrennraum oberhalb des Brennrostes durch den Brennrost nach unten in eine Nachbrennkammer, einem Wärmetauscher mit mehreren Wärmetauscherelementen der von den Rauchgasen durchströmt wird und die Wärme an den Flüssigkeitskreislauf überträgt, insbesondere entlang der Seitenwände angeordnet ist, wobei die Wärmetauscherelemente, insbesondere Wärmetauscherrippen, über weniger als 30 %, insbesondere weniger als 20 %, insbesondere weniger als 15 %, ihrer Fläche in körperlichem Kontakt mit dem Flüssigkeit führenden Teil des Wärmetauschers stehen.

Solid fuel combustion device, in which the risk of permanent deposition of combustion residues on the heat exchanger elements is greatly reduced despite simple and inexpensive construction of the combustion device, with heat exchanger for heat transfer to a liquid circulation, with a combustion grate for applying a solid fuel, in particular wood, a flue gas Discharge from the main combustion chamber above the combustion grate through the combustion grate down in a secondary combustion chamber, a heat exchanger with a plurality of heat exchanger elements is traversed by the flue gases and transfers the heat to the liquid circuit, in particular along the side walls is arranged, wherein the heat exchanger elements, in particular heat exchanger fins, over less than 30%, in particular less than 20%, in particular less than 15%, of their surface are in physical contact with the liquid-carrying part of the heat exchanger.
