Abstract

Die Erfindung betrifft eine Mischvorrichtung zum Mischen von Brenngas und Luft in einem definierten Mischungsverhältnis, auf der Basis einer Venturidüse. In einem Luftkanal ist ein Drosselmittel vorgesehen. Mit zunehmender Luftgeschwindigkeit werden Luftkanal und Drosselmittel so gegeneinander verschoben, dass sich der zwischen Luftkanal und Drosselmittel freibleibende Querschnitt vergrößert. Mit dem Luftkanal oder Drosselmittel ist ein Ventil für das Brenngas verbunden, das proportional zur Querschnittsveränderung des Luftkanals geöffnet wird. Dadurch ist sichergestellt, dass die Mischvorrichtung Brenngas und Luft über einen sehr weiten Modulationsbereich in einem definierten Verhältnis mischt.
