Abstract

Es werden ein Verfahren und eine Vorrichtung zur Überwachung der Dichtheit eines von einem Gasbrenner (12) befeuerten Strahlrohres (14) angegeben, bei dem von einer Steuerung (28) des Brenners (12) ein Brennersignal (32) abgeleitet wird, das mindestens die Zustände BRENNER AUS bei ausgeschaltetem Brenner (12) und BRENNER EIN bei eingeschaltetem Brenner (12) einnehmen kann. Ferner wird der Abgasstrom des Brenners (12) überwacht und hiervon ein Abgassignal (34) abgeleitet, das mindestens die Zustände ABGAS AUS bei nicht mit ausreichendem Volumenstrom strömendem Abgas und ABGAS EIN bei ordnungsgemäß abströmendem Abgas annehmen kann. Brennersignal (32) und Abgassignal (34) werden miteinander verknüpft, um bei der Kombination BRENNER EIN und ABGAS AUS ein Fehlersignal (36) auszugeben (Fig. 1).

Figure imgaf001
The invention relates to a method and a device for monitoring the tightness of a jet pipe (14) fired by a gas burner (12) in which a burner signal (32) which derives at least the states from a controller (28) of the burner (12) BURNER OFF with burner off (12) and BURNER ON with burner ON (12). Furthermore, the exhaust gas flow of the burner (12) is monitored and derived therefrom an exhaust gas signal (34) which can assume at least the conditions exhaust gas at not flowing with sufficient volume flow exhaust gas and exhaust gas with properly flowing exhaust gas. The burner signal (32) and the exhaust gas signal (34) are linked together to output an error signal (36) in the combination BURNER IN and OFF GAS OFF (FIG. 1).
