Effect of Humidification Water on Semi-Dry Flue Gas Desulfurization

Abstract

AbstractEffects of humidification water parameters (ratio of humidification water to total water, location of humidification water) on semi-dry flue gas desulfurization removal efficiency has been experimentally investigated. The optimal values of the parameters were obtained under the experiment conditions, which were 30% for ratio of humidification water to total water and at 6 meters above the lime slurry nozzle. SO2 removal efficiency of the scrubber and the whole system can reach 72% and 87% respectively which are 14% and 6% higher than corresponding efficiency without humidification water
