  "text": "In order to reduce the emissions of NOx from the flue-gases of kiln firing and/or preheating/precalcining processes, BAT is to use one or a combination of the following techniques:\nA description of the techniques is provided in Section 1.5.2.\nTechnique\nApplicability\na\nPrimary techniques\nI.\nFlame cooling\nApplicable to all types of kilns used for cement manufacturing. The degree of applicability can be limited by product quality requirements and potential impacts on process stability\nII.\nLow NOx burners\nApplicable to all rotary kilns, in the main kiln as well as in the precalciner\nIII.\nMid-kiln firing\nGenerally applicable to long rotary kilns\nIV.\nAddition of mineralisers to improve the burnability of the raw meal (mineralised clinker)\nGenerally applicable to rotary kilns subject to final product quality requirements\nV.\nProcess optimisation\nGenerally applicable to all kilns\nb\nStaged combustion (conventional or waste fuels), also in combination with a precalciner and the use of optimised fuel mix\nIn general, can only be applied in kilns equipped with a precalciner. Substantial plant modifications are necessary in cyclone preheater systems without a precalciner.\nIn kilns without precalciner, lump fuels firing might have a positive effect on NOx reduction depending on the ability to produce a controlled reduction atmosphere and to control the related CO emissions\nc\nSelective non-catalytic reduction (SNCR)\nIn principle, applicable to rotary cement kilns. The injection zones vary with the type of kiln process. In long wet and long dry process kilns it may be difficult to obtain the right temperature and retention time needed. See also BAT 20\nd\nSelective catalytic reduction (SCR)\nApplicability is subject to appropriate catalyst and process development in the cement industry",
