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.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 supply 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.

Der Erfindung liegt die Aufgabe zu Grunde, die Verbrennungsqualität von Heizkesseln und Öfen zur Verbrennung von festen Brennstoffen zu optimieren.The invention is based on the object to optimize the quality of combustion of boilers and furnaces for the combustion of solid fuels.

Erfindungsgemäß treten in die Wirbelkammer (7) in der Nähe einer Stirnseite in Radialrichtung von außen her Verbrennungsgase und/oder Sekundärluft ein und die Wirbelkammer (7) weist an der gegenüberliegenden Stirnseite eine Querschnittsverringerung im Bereich der Ausmündung für die Verbrennungsgase auf.

Figure imgaf001
According to the invention, combustion gases and / or secondary air enter the vortex chamber (7) in the vicinity of an end face in the radial direction from outside, and the vortex chamber (7) has a cross-sectional reduction at the opposite end face in the area of the outlet for the combustion gases.
