Abstract
Systems for reducing nitrogen oxides in combustion exhaust gas include a selective catalytic reactor (SCR) assembly having a catalyst bed for receiving a flow of exhaust gas, an exhaust gas conduit for introducing exhaust gas to the SCR assembly, at least one nozzle for introducing cooling water into the exhaust gas before the exhaust gas exits the SCR assembly, and at least one reductant conduit for introducing at least one reductant into the exhaust gas to form a reductant/exhaust mixture before the exhaust gas exits the SCR assembly. Methods for reducing nitrogen oxides in combustion exhaust gas include introducing an exhaust gas into a SCR assembly, and introducing cooling water into the exhaust gas, reducing the temperature of the exhaust gas, and introducing at least one reductant into the exhaust gas to form a reductant/exhaust mixture before the exhaust gas exits the SCR assembly.
