  • Gas flow through injector jet
    Patent number: 5569865
    Abstract: A method for monitoring the gas flow rate through injector jets comprises determining the pressure in a drawing tube downstream of the injector jet. The injector jet comprises a feed funnel extended by an injector tube opening into a gas distributor chamber having a gas feed line. The chamber is connected by a curved surface of revolution to an outlet duct. A drawing tube is downstream of the outlet duct, and both the outlet duct and the drawing tube have longitudinal axes that coincide with one another. The downstream end of the injector tube is situated at the junction of the outlet duct with the curved surface of revolution. The drawing tube has a pressure measuring device.
