  • Method of reducing NOemissions in rotary preheater mineral kilns
    Patent number: 7377773
    Abstract: This invention relates to a method to further enhance NOx reduction in rotary preheater mineral kilns by coupling the temperature control and gas composition uniformity afforded by the high temperature mixing with the use of chemical reducing agents. The chemical reducing agent or agents, generally chosen from ammonia or ammonia precursors, are introduced at a specific point in the rotary preheater kiln which has as an optimal temperature window to achieve the greatest reduction of NOx emissions.
    Type: Grant
