Abstract (en)
The mixing device has a mixing nozzle (1), particularly a Venturi nozzle, which has two air ducts (2,3) with a gas supply (4,5) in each case for guiding the air, and a closure unit (6), which comprises a flap (9). The closure unit is formed such that the flap closes the latter air duct or latter gas supply in a closed position during operation with low air mass flow rates. The air speed in the area of the latter gas supply in the transition area between low air mass flow rates and high air mass flow rates is so low that no enrichment of the combustion gas-air mixture takes place. An independent claim is included for a method for operating a mixing device.
Abstract (de)
Die Erfindung betrifft eine Mischvorrichtung zum Mischen von Brenngas und Luft in einem definierten Mischungsverhältnis, auf der Basis einer Venturidüse. In einem Luftkanal ist eine Klappe vorgesehen. Mit zunehmender Luftgeschwindigkeit wird die Klappe geöffnet. Ein Verriegelungsmittel verhindert, dass die Klappe im Übergangsbereich teilweise geöffnet ist.
