Combined process for removal of SO2, NOx, and particulates to be applied to a 1.6-MWe pulverized coal boiler

In this study, a combined process for the removal of SO2, NOx, and particulates at low temperature was suggested to minimize the scale and maximize the removal efficiency of equipment. Based on the results of the activity test for each process, a combined system could be designed, and its performance was also evaluated. SO2, dust, and NOx removal efficiencies were 94.15, 99.98, and 92.51%, respectively. It is believed that the system suggested in this study will be a very useful and popular system to control the air pollutants from coal boilers.
