EVALUATION OF THE COMBINOX PROCESS AT PILOT-SCALE

Under contract with the Department of Energy, EER is developing a NO(x) control process with potential to reduce NO(x) emissions from coal fired utility boilers by up to 85 %. CombiNO(x) is a family of NO(x) reduction processes which involves the synergistic application of combinations of technologies such as staged combustion, reburning, selective non-catalytic reduction (SNCR), and methanol injection. Any combination of these technologies can be applied to achieve a desired NO(x) reduction in a given boiler. Integration of these processes may be site-specific depending on boiler configuration and required emission limits.
