Abstract

Bei einer Strahlheizvorrichtung (1) soll eine Lösung geschaffen werden, die auf konstruktiv einfache Weise und kostengünstig eine vereinfachte und verbesserte Möglichkeit einer Überwachung der Strahlheizvorrichtung bereitstellt. Dies wird mit einer Strahlheizvorrichtung (1) für eine Ofenanlage erreicht, bei der eine Überwachungseinrichtung zur Ermittelung eines aktuellen Druckes in der Verbrennungsluftleitung (8) und/oder in der Verbrennungsgasleitung (10) unmittelbar vor Eintritt in das Gehäuse des zumindest einen Brenners (2) vorgesehen ist, die den aktuell ermittelten Druck an eine Brennersteuerung (5) ausgibt. Dabei ist die Überwachungseinrichtung und/oder die Brennersteuerung (5) derart ausgestaltet, dass sie den aktuell ermittelten Druck mit einem vorbestimmten Grenzwert vergleicht und/oder sie eine aus einem aktuell ermitteltem Druck und einem Druck einer korrespondierenden Sammelleitung gebildete Druckdifferenz Δp mit einem vorbestimmten Grenzwert vergleicht. Die Überwachungseinrichtung und/oder die Brennersteuerung (5) gibt ferner ein eine Undichtigkeit des keramischen Strahlheizrohres (3) anzeigendes Signal aus, wenn der aktuell ermittelte Druck den vorbestimmten Grenzwert unterschreitet und/oder wenn die aus aktuell ermitteltem Druck und einem Druck einer korrespondierenden Sammelleitung gebildete Druckdifferenz Δp einen vorbestimmten Grenzwert überschreitet.

Figure imgaf001
In a jet heating device (1), a solution is to be created which provides a simplified and improved possibility of monitoring the jet heating device in a structurally simple manner and cost-effectively. This is achieved with a jet heating device (1) for a furnace installation, in which a monitoring device for determining a current pressure in the combustion air line (8) and / or in the combustion gas line (10) immediately before entry into the housing of the at least one burner (2). is provided, which outputs the currently determined pressure to a burner control (5). In this case, the monitoring device and / or the burner control unit (5) is designed such that it compares the currently determined pressure with a predetermined limit value and / or compares a pressure difference Δp formed from a currently determined pressure and a pressure of a corresponding manifold with a predetermined limit value , The monitoring device and / or the burner control (5) also emits a signal indicating a leakage of the ceramic radiant heating tube (3) if the currently determined pressure falls below the predetermined limit value and / or if the pressure determined from the currently determined pressure and a pressure of a corresponding manifold Pressure difference Δp exceeds a predetermined limit.
