Abstract

Die Erfindung betrifft einen Heizkessel zur Verbrennung von festen Brennstoffen, mit einem Heizmedium führenden Kesselkörper (1), einem Füllraum (2) für Brennstoff mit einer oberen oder seitlichen Befüllöffnung (3), einem Brennrost (4) mit einem darunter angeordnetem Aschekasten (5), einer Primärluftzuführung im Bereich des Füllraumes, einer Verbrennungsgasaustrittsöffnung (6) in eine nachgeschaltete Wirbelkammer (7) sowie mit einem sich anschließenden Wärmetauscher für das Heizgas, wobei in die Wirbelkammer (7) in der Nähe einer Stirnseite von außen her Verbrennungsgase und/oder Sekundärluft eintreten. Der Erfindung liegt die Aufgabe zu Grunde, die Verbrennungsqualität von Heizkesseln und Öfen zur Verbrennung von festen Brennstoffen, insbesondere Biomasse, zu optimieren. Erfindungsgemäß umfasst die Wirbelkammer (7) einen ersten hohlzylindrischen Bereich (7a) und einen damit über einen Querschnittssprung (8) gekoppelten zweiten Bereich (7b) in der Form eines rotationssymmetrischen Hohlkörpers mit einer stirnseitigen Ausmündung (9) für die Verbrennungsgase.The invention relates to a boiler for burning solid fuels, comprising a boiler body (1) carrying a heating medium, a filling space (2) for fuel with an upper or lateral filling opening (3), a grate (4) with an ash box (5) arranged underneath. , a primary air feed in the region of the filling chamber, a combustion gas outlet opening (6) in a downstream vortex chamber (7) and with a subsequent heat exchanger for the heating gas, wherein in the vortex chamber (7) in the vicinity of a front side from the outside combustion gases and / or secondary air enter. The invention is based on the object to optimize the quality of combustion of boilers and furnaces for the combustion of solid fuels, especially biomass. According to the invention, the vortex chamber (7) comprises a first hollow-cylindrical region (7a) and a second region (7b) coupled thereto via a cross-sectional jump (8) in the form of a rotationally symmetrical hollow body with an end-side orifice (9) for the combustion gases.
