  • CEMENT CLINKER PRODUCTION WITH REDUCED EMISSIONS
    Publication number: 20100071598
    Abstract: The carbon monoxide and hydrocarbon content of flue gas in a cement clinker production apparatus is lowered by feeding a high velocity stream of hot oxygen into the flue gas. Methods and apparatus for producing the hot oxygen stream are disclosed.
    Type: Application
    Filed: September 25, 2008
    Publication date: March 25, 2010
    Inventors: Stefan Ernst Friedrich Laux, Lee Jonathan Rosen

  • Controlling jet momentum in process streams
    Publication number: 20080006225
    Abstract: A gaseous process stream that can be directed into a workspace or toward a workpiece is formed by feeding fuel, oxidant and process material into a thermal nozzle. The fuel combusts in the thermal nozzle with the oxidant and with combustible components, if any, of the process material, to form the gaseous process stream which is emitted from the thermal nozzle at high and controllable velocity and momentum.
