Abstract

Die Erfindung betrifft ein Verfahren zum Einstellen eines Ausgangsdrucks (Pout) eines Brenngasvolumenstromes an einem Ausgang eines Gasventils für ein Verbrennungssystem. Weiter betrifft die Erfindung eine Vorrichtung (4) zum Einstellen eines Ausgangsdrucks (Pout) eines Brenngasvolumenstromes an einem Ausgang eines Gasventils für ein Verbrennungssystem. Auch betrifft die Erfindung eine Brenngas-Luft-Mischeinrichtung (10), insbesondere eine Brenngas-Luft-Mischeinrichtung (10) zum Erzeugen und Zuführen eines Brenngas-Luft-Gemisches (M) für ein Verbrennungssystem. Zudem betrifft die Erfindung ein Verbrennungssystem.
Es ist eine Aufgabe der Erfindung, eine Vorrichtung (4) und ein Verfahren zum Einstellen eines Ausgangsdrucks (Pout) eines Brenngasvolumenstromes an einem Ausgang eines Gasventils für ein Verbrennungssystem zu schaffen, welche weniger empfindlich und stabiler auch über einen größeren Glasdurchflussbereich sind. Weiter liegt der Erfindung die Aufgabe zugrunde, ein Brenngas-Luft-Mischeinrichtung (10), mit einer erfindungsgemäßen Vorrichtung (4) zu schaffen, welche eine effektive Arbeitsweise bei reduziertem Gesamtaufwand realisieren, und die auch bei größeren Durchflüssen stabil und unempfindlich arbeiten.
Gekennzeichnet ist das Verfahren dadurch, dass der Ausgangsdruck (Pout) des Brenngases (B) zweistufig eingestellt wird. Gekennzeichnet ist die Vorrichtung (4) dadurch, dass Mittel zum Durchführen des erfindungsgemäßen Verfahrens vorgesehen sind. Gekennzeichnet ist die Brenngas-Luft-Mischeinrichtung (10) dadurch, dass mindestens eine erfindungsgemäße Vorrichtung (4) vorgesehen ist. Gekennzeichnet ist das Verbrennungssystem (10) dadurch, dass mindestens eine erfindungsgemäße Brenngas-Luft-Mischeinrichtung (10) vorgesehen ist.
