METHOD AND DEVICE FOR CLEANING FLUE GASES FROM NITRIC OXIDES BY SELECTIVE NONCATALYTIC REDUCTION |
摘要 |
FIELD: chemical cleaning of flue gases from nitric oxides. SUBSTANCE: proposed method includes preparation of ammonia from ammonia liquor through evaporation by means of heating steam and introduction of mixture of ammonia with steam to flow of combustion products; flow rate of heating steam is regulated assuming that no more than 15% of aqueous phase is evaporated from ammonia liquor before introduction of mixture into gaseous combustion products. Mixture is introduced into combustion products in counter flow. Invention contains description of device used for realization of this method. EFFECT: enhanced efficiency of cleaning flue gases. 3 cl, 2 dwg
