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.
