Badania suchego odsiarczania i odazotowania spalin w binarnej cyrkulacyjnej warstwie fluidalnej

The flue gas passed through an MSFB reactor for simultaneous dry removal of SOx and NOx.The dense layer of the bed consisted of coarse urea grains,which acted as a source of ammonia (the activator of the denitrification process). The circulating layer was made of fine CuO particles and fine Ca(OH)2 grains,acting as a catalyst and a sorbent,respectively.The efficiencies of removal were remowal were related to temperature, Ca/S ratio,urea/NO ratio,flue gas velocity,and SO2 concentration in the flue gas stream.The highest efficiency of SOx was achieved at 400.o C .When the Ca/S and urea/NO ratios increased,so did the efficiencies of removal for sulfur dioxide and nitrogen oxides.NOx removal efficiency reached its maximum efficiency of SOx removal.
