  • Method for Zonal Injection of Chemicals into a Furnace Convective Pass to Reduce Pollutants from Flue Gases
    Publication number: 20090047199
    Abstract: Zonal injection of varying compositions of chemicals, particularly an ammonia-based reagent and hydrocarbon, through injection lances arranged in a grid formation to define planar zones in a furnace convective pass of a furnace. The supply of chemicals is controlled so as to be individually determined for each discrete zone of the grid depending on conditions in that zone.
    Type: Application
    Filed: October 29, 2008
    Publication date: February 19, 2009
    Inventors: Stuart Arrol, Peter Melling, G.A. Yates, Michael J. Smith, Gerard J.W.C. Hesselmann, Barbara Lefebvre, John Macphail, Keith W. Morris
