Abstract
PURPOSE: To economically obtain highly active quick and highly conc. NOx by concentrating dil. waste liquuor of calcium nitrate to dryness at a specified temp. or below in an indirect heating type rotary kiln and adding a specified amt. of quick lime followed by thermal decomposition at a specified temp. in a direct heating type rotary kiln.
