Application of calcium propionate and ammonia water in simultaneous denitrification and desulfurization of the flue gases
Flue gases from coal combustion were denitrificated and desulfurized with NH3 water (concn. 3%) and Ca propionate soln. (concn. 20%). The simultaneous use of both reagents enhanced the NO redn. efficiency under minimization of unreacted NH3 in flue gas and fly ash. Use of Ca propionate increased the NO redn. up to 82% and SO2 redn. up to 80%.
