Abstract
A selective catalytic reduction system (SCR) or selective non-catalytic reduction (SNCR) system include a reagent charging apparatus configured to apply one or more electrical charges to a NOx reducing reagent. The electrical charges enhance mixing of the reagent with fluids carrying NOx and/or enhance reactivity of the reagent with NOx.
