The system includes a urea inlet, a steam inlet, and a reactor in fluid communication with the urea inlet and the steam inlet The reactor is configured and adapted to inject urea from the urea inlet into a steam flow from the steam inlet to convert the urea into at least one reactant for N0씟 reduction within a substantially gaseous mixture. The invention also provides a method of converting urea into reactants for reducing N0씟 out of industrial emissions. The method includes injecting urea into a steam flow to convert the urea into at least one reactant for N0씟 reduction within a substantially gaseous mixture.

Systems and methods for removing materials from flue gas via regenerative selective catalytic reduction
x levels in gases are reduced by mixing the gas with a reactant and then introducing the gas into an RSCR apparatus for treatment that entails heating the gas, causing the gas to undergo one or more catalytic reactions, and then directing the gas through a heat transfer area, to which the gas provides heat for use in connection with successive cycles of the RSCR process.
This invention relates generally to the treatment of NOx in combustion flue gas. In certain embodiments, the invention relates to the use of a regenerative heat exchanger (RHE) to convert urea to ammonia in a side stream of flue gas. Ammonia and/or other urea decomposition products exit the heat exchanger,- are mixed with the rest of the flue gas, and enter a selective catalytic reduction (SCR) unit for reduction of NOx in the flue gas. The use o an RHE significantly improves the thermal efficiency of the overall process. More particularly in certain embodiments, the regenerative heat exchanger is a dual chamber RHE.
