METHOD OF REMOVING NITROGEN OXIDES FROM FLUE GASES

摘要

FIELD: gas treatment. SUBSTANCE: flue gas is treated at 700-120 C by urea thermal decomposition products produced by heating solid urea beyond the nitrogen oxide reduction zone while simultaneously blowing through solid urea layer to produce gas mixture that is further directed into the nitrogen oxide reduction zone. EFFECT: increased flue gas purification degree and simplified technology. 4 cl, 2 dwg , 2 tbln
