Reducing NOx from existing cement kiln lines IEEE
Abstract: In cement kiln lines, significant amounts of NOx emissions can be formed both in the rotary kiln and in the precalciner To reduce NOx formation, low NOx techniques can be applied to the burner and to the combustion systems used in the rotary kilns and precalciners, respectively These low NOx techniques have the dual advantage of (i) low CAPEX cost and (ii) no additional operating provides sustainable productivity to the global mining and cement industries We deliver marketleading engineering, equipment and service solutions that enable our customers to improve performance, drive down costs and reduce environmental impact Our operations span the globe and our close to 11,000 employees are present in more than Reduce thermal NOx generated in cement kilns A further pressure on cement producers in the United States is to reduce nitrogen oxide (NOx) emissions that are a byproduct of the cement manufacturing process Cement manufacturing conditions are particularly favorable for formation of NOx because of the high process temperatures and oxidizing atmospheres involved Since NOx is an ozoneforming precursor, uncontrolled or under controlled NOx NOx Reduction Process in a Cement Kiln Manufacturing NOx from cement production reduction by primary measures abstract = "This thesis comprises an investigation of the mechanisms involved in forming andreducing NOxin kiln systems forcementproductionrotary cement operation nox reducing PAIN Heavy MachineryMethod and apparatus for reducing NOx emissions in rotary kilns by SNCR AU ABSTRACT PATENT DETAILS Inventor/s: Blankenship, Kevin; Derksen, Kenneth J Hansen, Eric R Parker, Walter ; Supelak, Ralph A Tutt, James R Assignee/s: Ash Grove Cement Company; Cadence Environmental Energy, Inc W O 2 0 0 7/0 8 2 19 8 A 3 (88) Date of publication of the international Method and apparatus for reducing NOx emissions in rotary
