Abstract
PURPOSE: To utilize effectively the by-products and to reduce the amount of chemicals for the denitration, by converting nitrite generated at the absorption process to NO and nitrate by decomposing with by-product nitric acid, then by circulating and adding NO2 oxidized from NO into the waste gas and thus by converting nitrate to Ca(NO3)2.
