SNCR Retrofit of a Lignite Power Plant to Meet the new EC NOx-Limit of 200 mg/Nm3

摘要

NO_x emissions could be lowered very effectively and cost-efficiently by the application of modern SNCR-technology. Therefore, the SNCR-technology already entered into the field of large-scale power plants over the last years [1, 2, 3]. Especially in case of older boiler plants, with a limited term, this technology is preferred [4]. Major investments in alternative technologies do not turn out to be economical any longer due to their limited remaining operational time.
