Investigation of SO2, HCl and NOx control from waste incinerators using a novel additive in a pilot scale reactor

A pilot scale experimental investigation of the use of a novel additive, calcium magnesium acetate, for the simultaneous control (if SO2, HCl and NOx has been carried cut. The pilot scale reactor simulated the furnace and flue gas conditions of a typical large scale waste incinerator and was a vertical 4m high reactor operated at 80kW. The calcium magnesium acetate was added as a wet spray to the reactor at temperatures above 750 degrees C. The influence (if the calcium magnesium acetate dose rate was investigated on the simultaneous removal of SO,, HCl and NOx. Maximum reductions were achieved at a Ca/S ratio (or Ca/Cl ratio) of 2.5 and were, 70% for SO2, 45% for HCl and for NOx for each of the pollutant gases respectively.
