Abstract
Die Erfindung bezieht sich auf einem Mischer für gasförmige Medien mit einem Venturi-Rohr, durch das in Rohrachsrichtung ein Gas strömt und in dessen Bereich mit verengtem Querschnitt (7) an der Rohrwand Eintrittsöffnungen (8) für beizumischendes Gas vorgesehen sind, wobei die Durchlassquerschnitte (21) der Eintrittsöffnungen (8) im Betrieb während des Mischungsvorganges mittels Regelgliedern (14) veränderbar sind und ein Verfahren unter Einsatz des Mischers. The invention relates to a mixer for gaseous media with a Venturi tube through which a gas flows in the tube axis direction and in the region of narrowed cross-section (7) on the tube wall inlet openings (8) are provided for admixing gas, wherein the passage cross sections ( 21) of the inlet openings (8) during operation during the mixing process by means of control elements (14) are variable and a method using the mixer.
