  • METHOD AND APPARATUS FOR REDUCING NOx EMISSIONS IN ROTARY KILNS BY SNCR
    Publication number: 20080070177
    Abstract: A method of operating a mineral processing kiln includes introducing a quantity of a selective non-catalytic reduction (SNCR) reducing agent into the kiln. The SNCR reducing agent may be a solid, liquid, or a gas. A mineral processing kiln modified for the implementation of SNCR is also disclosed.

  • METHOD OF MIXING HIGH TEMPERATURE GASES IN MINERAL PROCESSING KILNS
    Publication number: 20070207432
    Abstract: A method is described for reducing NOx emissions and improving energy efficiency during mineral processing in a rotary kiln. The method comprises injection of air with high velocity/high kinetic energy into the kiln to reduce or eliminate stratification of kiln gases. The method can be applied to mix gases in a rotary kiln vessel or in a preheater/precalciner vessel.
