Method of mixing high temperature gases in mineral processing kilns |
摘要 |
A method is described for reducing NO<SUB>x </SUB>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.
