Gas reburning (GR) is a cost-effective technique for achieving 50-60% NOx control in industrial and utility boilers. However, forthcoming legislation will require increased levels of NOx control (70-90%), for which selective catalytic reduction (SCR) is considered to be the state-of-the-art technology. SCR is relatively expensive, and it poses potential problems with reagent handling and spent catalyst disposal. Thus, what is needed is a technology capable of economically providing high-level NOx control without the generation of toxic waste products. The proposed technology will meet this need through the development of an innovative means of enhancing performance of the GR technology. Inexpensive, readily-available additives will be injected during reburning to increase NOx control via heterogeneous reactions. The process will be suitable for integration into new or existing utility and industrial boilers. It will be capable of providing high-level NOx control while retaining the cost effectiveness of GR and not generating any toxic byproducts.
