Abstract

Die Erfindung betrifft eine Sicherheitsanordnung für einen Brenner (2), der an eine Brennstoffleitung (1) angeschlossen ist und der mittels einer Brennersteuerung (3) gesteuert wird. In der Brennstoffleitung (1) sind hintereinander zwei Ventile (4) angeordnet, die mit Stellgliedern (5) versehen sind.The invention relates to a safety arrangement for a burner (2) which is connected to a Fuel line (1) is connected and that by means of a burner control (3) is controlled. Two valves (4) are arranged one behind the other in the fuel line (1), which are provided with actuators (5).

Eine Dichtheit-Prüfeinheit (7), die an einen Drucksensor (6) angeschlossen ist, dient dazu, den Dichtsitz der beiden Ventile (4) zu prüfen. Mittels einer Brennstoff-Prüfeinheit (8) wird in der Brennersteuerung (3) bei einer Wärmeanforderung der Programmablauf zum Start des Brenners erst dann freigegeben, wenn ein Sensor das Vorhandensein von Brennstoff meldet.A leak test unit (7), which is connected to a pressure sensor (6), is used to check the tight fit of the two valves (4). Using a fuel test unit (8) in the burner control (3) when a heat request, the program sequence released to start the burner only when a sensor the presence of fuel reports.

Erfindungsgemäß ist die Brennstoff-Prüfeinheit (8) an den Drucksensor (6) der Dichtheits-Prüfeinheit (7) angeschlossen, so daß das Ausgangssignal des Drucksensors (6) mehrfach ausgenutzt wird. Der Verzicht auf mindestens einen zusätzlichen Drucksensor und den zugehörigen Verdrahtungsaufwand führt zu einer Kostensenkung.

Figure 00000001
According to the invention, the fuel test unit (8) is connected to the pressure sensor (6) of the leak test unit (7), so that the output signal of the pressure sensor (6) is used several times. The elimination of at least one additional pressure sensor and the associated wiring effort lead to a cost reduction.
