Abstract
Description
Die Erfindung bezieht sich auf einen Heizkessel mit einem vorzugsweise zylindrischen Brennraum, einem Kesselraum für das Heizwasser und mindestens einem Rauchzug, wobei der Kesselraum einen Zylinder mit vertikaler Längsachse beschreibt und die Längsachse des Brennraumes, der in den Kesselraum ragt, zumindestens annähernd horizontal ausgerichtet und die Rauchzüge vom Brennraum zur oberen Abschlußwand des Kesselraumes führen und wobei im Brennraum ein Ölgebläsebrenner mit annähernd horizontaler Flammrichtung angeordnet ist. Ein derartiger Heizkessel ist aus dem Dokument DE-A-1 454 507 bekannt.The invention relates to a boiler with a preferably cylindrical combustion chamber, a boiler room for the heating water and at least one flue, the boiler room describes a cylinder with a vertical longitudinal axis and the longitudinal axis of the combustion chamber, which projects into the boiler room, at least approximately horizontally aligned and the Smoke leads from the combustion chamber to the upper end wall of the boiler room and an oil-blowing burner with an approximately horizontal flame direction is arranged in the combustion chamber. Such a boiler is known from document DE-A-1 454 507.
Nach dem bekannten Stand der Technik besteht die Heizeinrichtung eines Wohnhauses im allgemeinen aus drei Gruppen, nämlich dem Heizkessel mit dem Brennraum, einer oder mehrerer Verteilereinrichtungen und einem Boiler. Diese sind als baulich separate Einheiten gefertigt und nehmen entsprechend viel Raum ein. Ein weiterer Nachteil ist, daß der Betrieb des Heizkessels relativ laut ist und besonders in der Übergangszeit und im Sommer bei Brauchwasserbetrieb relativ hohe Bereitschaftsverluste beim Heizwasser auftreten.According to the known prior art, the heating device of a residential house generally consists of three groups, namely the boiler with the combustion chamber, one or more distribution devices and a boiler. These are built as structurally separate units and accordingly take up a lot of space. Another disadvantage is that the operation of the boiler is relatively loud and, especially in the transition period and in summer when there is hot water operation, there are relatively high standby losses in the heating water.
Aufgabe der Erfindung ist es, einen Heizkessel der eingangs erwähnten Art dahingehend zu verbessern, daß eine optimale Aufbereitung des Heizwassers und ein ruhiger Heizbetrieb möglich ist.The object of the invention is to improve a boiler of the type mentioned in such a way that an optimal preparation of the heating water and a quiet heating operation is possible.
Dies wird erfindungsgemäß dadurch erreicht, daß mehrere vorzugsweise vier Rauchzüge vorgesehen sind, die geradlinig und schräg vom vorderen Bereich des Brennraumes zur Mitte der oberen Abschlußwand des Kesselraumes verlaufen und daß der Brennraum nach hinten geneigt ist.This is achieved according to the invention in that several, preferably four, smoke flues are provided which run in a straight line and obliquely from the front region of the combustion chamber to the center of the upper end wall of the boiler chamber and in that the combustion chamber is inclined to the rear.
Dadurch, daß die Rauchzüge vorne in den Brennraum münden und oben mittig aus dem Kesselraum austreten, ist einerseits eine sehr leichte Reinigung der Rauchzüge möglich und andererseits kann oben ein drehbarer Rauchgasanschluß vorgesehen sein, sodaß der erfindungsgemäße Heizkessel in jeder beliebigen Richtung an einen Abgasanschluß angeschlossen werden kann.The fact that the smoke flues open into the front of the combustion chamber and emerge from the center of the boiler chamber at the top enables very easy cleaning of the smoke flues and a rotatable flue gas connection can be provided at the top so that the boiler according to the invention can be connected to an exhaust gas connection in any direction can.
Um das Ablaufen des Kondenzwassers zu erleichtern, ist in einem vorteilhaften Ausführungsbeispiel vorgesehen, daß der Brennraum in einem Winkel von etwa 5° nach hinten geneigt ist.In order to facilitate the running of the condenser water, it is provided in an advantageous embodiment that the combustion chamber is inclined to the rear at an angle of approximately 5 °.
Um eine möglichst geringe Stellfläche für den Heizkessel und die damit verbundenen Armaturen zu erreichen, ist in einem weiteren Ausführungsbeispiel der Erfindung vorgesehen, daß die Einheit Brennraum und Kesselraum zusammen mit Verteilerrohren und Verteilerarmaturen der Heizkreise und einem Wärmetauscher für Brauchwasser in einem wärmeisolierten Heizschrank angeordnet sind.In order to achieve the smallest possible footprint for the boiler and the associated fittings, it is provided in a further exemplary embodiment of the invention that the combustion chamber and boiler space unit are arranged in a heat-insulated heating cabinet together with distributor pipes and distributor fittings for the heating circuits and a heat exchanger for process water.
