    • PROBLEM TO BE SOLVED: To provide a heat recovery steam generator for use in reducing NOformation in the exhaust path of a combustion system and for regenerating a catalytic material that facilitates the reduction in NOformation.SOLUTION: The heat recovery steam generator (HRSG) 116 is coupled in flow communication downstream from a combustion device 106 that produces a flow of exhaust gases. The steam generator includes: a heating device configured to heat the exhaust gases discharged from a gas turbine engine 106 and including oxides of nitrogen (NOx); and an oxidation catalyst coupled downstream from the heating device. The oxidation catalyst facilitates reducing an amount of NOx in the exhaust gases channeled into the oxidation catalyst at a first temperature that is less than a thermal regeneration temperature for a catalytic material and at a second temperature that is approximately equal to at least the thermal regeneration temperature such that the catalytic material is simultaneously regenerated.
