Abstract

Der Erfindung liegt die Aufgabe zugrunde, ein Heizgerät mit atmosphärischer Feuerung und Abgasüberwachungseinrichtung sowie ein Verfahren zu seinem Betreiben zu schaffen, die einen Abgasaustritt in den Aufstellraum sicher detektieren und insbesondere Sicherheit gegenüber unzulässiger Manipulation bieten, durch die der Betreiber oder Installateur die Betriebssicherheit des Heizgerätes gefährden könnte.The invention has for its object to provide a heater with atmospheric firing and exhaust gas monitoring device and a method for its operation, which reliably detect an exhaust gas outlet in the installation and in particular provide security against improper manipulation, endanger the reliability of the heater by the operator or installer could.

Das erfindungsgemäße Heizgerät ist dadurch gekennzeichnet, dass die Abgasüberwachungseinrichtung einen thermoelektrischen Generator umfasst, welcher eine wärmeleitende Verbindung zum Inneren des Heizgerätes aufweist. Der thermoelektrische Generator ist an einer Stelle angeordnet, die bei eingeschalteter Brennerfeuerung in einem normalen (zulässigen) Regelbetrieb des Heizgerätes von Luft aus der Umgebung des Heizgerätes umströmt und gekühlt ist. Unter Einfluss einer sich einstellenden Temperaturdifferenz T1 zwischen den Bereichen A und B erzeugt der thermoelektrische Generator eine elektrische Leistung L1, ein Signal S1, eine Spannung U1 oder einen Strom J1, unter dessen Einfluss ein die Brennstoffversorgung regelndes Brennstoffventil öffnet und/oder offen gehalten wird. Bei eingeschalteter Brennerfeuerung und mindestens teilweisem Verschluss der Abgasleitung oder anderweitig bedingtem Abgasaustritt in den Aufstellraum, und somit in einem unzulässigen Betriebszustand, ist der thermoelektrische Generator von Abgas aus dem Heizgerät umströmt und erwärmt. Unter Einfluss einer sich einstellenden Temperaturdifferenz T2 < T1 zwischen den Bereichen A und B erzeugt der thermoelektrische Generator eine elektrische Leistung L2 < L1, ein Signal S2, eine Spannung U2 < U1 oder einen Strom J2 < J1, unter dessen Einfluss das Brennstoffventil schließt bzw. nicht öffnet.

The heater according to the invention is characterized in that the exhaust gas monitoring device comprises a thermoelectric generator, which has a heat-conducting connection to the interior of the heater. The thermoelectric generator is arranged at a location that flows around when the burner firing in a normal (allowable) control operation of the heater of air from the environment of the heater and cooled. Under the influence of an adjusting temperature difference T1 between the areas A and B, the thermoelectric generator generates an electrical power L1, a signal S1, a voltage U1 or a current J1, under the influence of which a fuel supply regulating fuel valve opens and / or kept open. When the burner firing and at least partial closure of the exhaust pipe or otherwise conditional exhaust gas outlet in the installation room, and thus in an impermissible operating state, the thermoelectric generator of exhaust gas from the heater is flowed around and heated. Under the influence of an adjusting temperature difference T2 <T1 between the areas A and B, the thermoelectric generator generates an electrical power L2 <L1, a signal S2, a voltage U2 <U1 or a current J2 <J1, under whose influence the fuel valve closes or not open.
