NOH{sub}x formation in rotary kilns producing cement clinker applicable NOH{sub}x control techniques and cost effectiveness of these control techniques

摘要

The Portland Cement Association commissioned a study of information available related to NO{sub}x formation in rotary kilns producing cement clinker, potential NO{sub}x control techniques, NO{sub}x 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 NO{sub}x emissions and control related to rotary kilns in the cement manufacturing industry. Descriptions of predominate NO{sub}x formation mechanisms and control techniques are provided. An assessment of the technical feasibility, the NO{sub}x 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.
