摘要
The process is by injection of calcium chloride into the combustor and lowering the flue gas temperature in sufficient time to enhance oxidation of mercury and nitrogen oxides into more soluble products prior to their absorption in a wet scrubber. The additive also increases the alkalinity and the pH of the scrubber water, therefore, favorably increasing the absorption of the pollutants. The flue gas is then cooled to ambient temperature or less to enhance the removal of mercury.
