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.
Claims78
A selective nitrogen oxide (NOx) reduction system, comprising:
- a reagent charging apparatus configured to apply electrical charges to a selective nitrogen oxide reduction reagent;
- and
- a reagent launcher operatively coupled to the reagent charging apparatus and configured to launch the charged reagent into a flue gas produced by a combustion reaction.

A method for operating a nitrogen oxide (NOx) control system, comprising:
- applying first electrical charges to a selective nitrogen reduction reagent;
- and
- injecting the charged reagent into a flue gas from a combustion reaction;
- wherein the electrical charge is selected to enhance mixing of the reagent with NOx or to enhance reactivity of the reagent with NOx to reduce the NOx to molecular nitrogen (N2).
