Abstract:The current main techniques of denitrification for alkali recovery boilers including in furnace injection of denitrification reducing agent, SCR denitrification, ClO2 oxidation denitrification, ozone oxidation denitrification and LCO-RRI denitrification patent technology, were discussed.The principle and application of each technique were introduced separately, and the patented technology LCO-RRI of our company (low carbon monoxide reducing agent in-furnace injection denitrification technology) was mainly introduced.Finally, through a comprehensive economic analysis of investment and operating costs, the “two step” implementation strategy was suggested, which not only could meet the requirements of environmental protection and emission reduction, and also could maximize economic optimization.
