This project's goal is to demonstrate the removal up to 70% of the NO{sub x} and 70% of the SO{sub 2} emissions from coal fired utility boilers. It will establish an alternative emissions control technology integrating a combination of several processes, while minimizing capital expenditures and limiting waste production to dry solids that are handled with convention ash removal equipment. These processes include low-NO{sub x} burners and urea injection for NO{sub x} control, sodium- or calcium-based sorbent injection for SO{sub 2} control, and flue gas humidification to enhance the reactivity of the SO{sub 2} control compound.
