Abstract :
The Portland Cement Association commissioned a study of information available related to NOx formation in rotary kilns producing cement clinker, potential NOx control techniques, NOx control techniques applicable to the cement manufacturing industry, and the cost effectiveness of the applicable controls. This paper is a summary of the PCA report and other articles and information concerning NOx emissions and control related to rotary kilns in the cement manufacturing industry. Descriptions of predominate NOx formation mechanisms and control techniques are provided. An assessment of the technical feasibility, the NOx reduction potential, the potential effect on other pollutants, and a range of cost effectiveness for control techniques applicable to the cement manufacturing industry are provided
