SNCR: when the equation no longer holds28 November 2023, Published under Cement NewsThere are plants where selective non-catalytic reduction (SNCR) does not achieve the expected DeNO X results for no apparent reason. Often a look at the chemical processes in the background provides a clue as to why successful denitrification is failing. By Karin Koglbauer, DyCarnica, Austria. Figure 1: chemical DeNOx behaviour-ammonia vs urea (© DyCarnica) Selective non-catalytic reduction (SNCR) refers to selective flue gas denitrification without a catalyst at 800-1100˚C. G... |
