Abstract
Bei Wärmezelle (8) mit einem brennstoffbetriebenen Brenner (1), welchem von einer Brenngasdosiereinrichtung (15) in Abhängigkeit des Drucks in einer Steuerdruckleitung (14) Brenngas zugeführt wird, einem Wärmetauscher (9) zur Übertragung thermischer Energie der Abgase des Brenners (1) auf eine Wärmesenke und einem Gehäuse (10) mit einer Öffnung, welche durch eine demontierbare Brennertür (4) verschließbar ist, ist auf der einen Seite der Brennertür (4) der Brenner (1) montiert. Die andere Seite der Brennertür (4) ist mit einer Brenngas-Luft-Zuführung (3) zur Zuführung eines Brenngas-Luft-Gemisch verbunden. Zwischen dem Gehäuse (10) und der Brennertür (4) ist die Steuerdruckleitung (14) angeordnet. Bei einer Undichtheit schmilzt die Steuerdruckleitung (14), wodurch die Brenngasführung zum Erliegen kommt und das Gerät abschaltet.In the case of a heat cell (8) with a fuel-operated burner (1), which is supplied with fuel gas from a fuel gas metering device (15) as a function of the pressure in a control pressure line (14), a heat exchanger (9) for transmitting thermal energy of the exhaust gases of the burner (1) on a heat sink and a housing (10) having an opening which can be closed by a removable burner door (4), on one side of the burner door (4) of the burner (1) is mounted. The other side of the burner door (4) is connected to a fuel gas air supply (3) for supplying a fuel gas-air mixture. Between the housing (10) and the burner door (4), the control pressure line (14) is arranged. In the event of a leak, the control pressure line (14) melts, as a result of which the combustion gas supply stops and the device switches off.
Description
Die Erfindung bezieht sich auf eine Vorrichtung und ein Verfahren zur Erkennung einer Undichtheit einer Wärmezelle eines Heizgerätes mit einem brennstoffbetriebenen Brenner sowie einer gegenüber der Umgebung abgedichteten Brennkammer.The invention relates to a device and a method for detecting a leakage of a heat cell of a heater with a fuel-operated burner and a sealed relative to the surrounding combustion chamber.
Bei Heizgeräten mit einem brennstoffbetriebenen Brenner werden etwa 1300℃ heiße Abgase abgekühlt und diese Wärme Heizkörpern für Raumwärme und einer Brauchwassererwärmung zugeführt. Die Brennkammer ist hierbei zumeist über eine demontierbare Brennertür mit einer temperaturbeständigen Dichtung gegenüber der Umgebung abgedichtet. Bei Wartungsarbeiten wird diese Brennertür mit der Dichtung demontiert und wieder montiert. Hierbei kommt es ab und an zu Beschädigungen der Dichtung oder einer fehlerhaften Montage, so dass im ungünstigen Fall heiße Abgase nach außen gelangen können und hierbei zu Schäden am Heizgerät führen.For heaters with a fuel-fired burner, about 1300 ℃ hot exhaust gases are cooled and this heat is supplied to radiators for space heating and domestic water heating. The combustion chamber is sealed here in most cases via a removable burner door with a temperature-resistant seal against the environment. During maintenance work, this burner door is dismantled and reassembled with the gasket. This occasionally causes damage to the gasket or faulty installation, so that in the worst case hot exhaust gases can escape to the outside and cause damage to the heater.
Aufgabe der Erfindung ist eine Sicherung gegen unbeabsichtigten Abgasaustritt aus Brennkammern mit einem brennstoffbetriebenen Brenner zu schaffen.The object of the invention is to provide protection against unintentional exhaust gas emissions from combustion chambers with a fuel-operated burner.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einer Wärmezelle mit einem brennstoffbetriebenen Brenner und einem Gehäuse mit einer Öffnung, welche durch eine demontierbare Brennertür verschließbar ist, zwischen dem Gehäuse und der Brennertür eine Steuerdruckleitung für die Brenngasdosierung angeordnet ist. Bei Störungen fällt der Steuerdruck ab, der Brenner bekommt in Folge dessen kein Brenngas und die Anlage schaltet ab.This object is achieved in that in a heat cell with a fuel-operated burner and a housing having an opening which can be closed by a removable burner door, between the housing and the burner door, a control pressure line for the fuel gas metering is arranged. In case of faults, the control pressure drops, the burner gets in consequence no fuel gas and the system switches off.
Vorteilhafte Ausgestaltungen ergeben sich aus den Merkmalen der abhängigen Ansprüche.Advantageous embodiments result from the features of the dependent claims.
So ist in dem Fall, wenn die Steuerdruckleitung am äußeren Rand der Brennertür verläuft, gewährleistet, dass im Störfall der Druck in der Steuerdruckleitung auf Umgebungsdruck abfällt. Die Steuerdruckleitung sollte die Brennertür zumindest annähernd vollständig umlaufen, damit auch an jeder fehlerhaften Stelle ein Austritt detektiert wird. Insbesondere oben sollte die Leitung an der Brennertür verlaufen. Als Werkstoff eignen sich solche mit einem Schmelzpunkt unter 300℃, vorzugsweise Kunststoff. Eine temperaturbeständige Dichtung sollte näher am Brenner angeordnet sein als die Steuerdruckleitung; diese schützt im ordnungsgemäßen Fall die Steuerdruckleitung. Erfindungsgemäß kann der Übergang vom Gehäuse auf die Brennertür optional auch lediglich durch die Steuerdruckleitung abgedichtet sein.So is in the case when the control pressure line runs on the outer edge of the burner door, ensures that in case of failure, the pressure in the control pressure line drops to ambient pressure. The control pressure line should at least approximately completely circulate the burner door, so that an outlet is detected at each faulty point. In particular, above the line should run to the burner door. Suitable materials are those with a melting point below 300 ℃, preferably plastic. A temperature-resistant seal should be located closer to the burner than the control pressure line; this protects the control pressure line in the proper case. According to the invention, the transition from the housing to the burner door can optionally also be sealed only by the control pressure line.
