To provide a power generating apparatus including a gas turbine engine for combusting a fuel in air to produce shaft power and producing a flow of exhaust gases including oxides of nitrogen (NOx), carbon monoxide (CO) and hydrocarbons (HC).
In the power generating apparatus 600, an emissions treatment apparatus 605 includes, in the exhaust gas flowpath, a CO oxidation catalyst 620 disposed at a location with an exhaust gas temperature for which the CO oxidation catalyst advantageously limits NO2 production. The emissions treatment apparatus 605 further includes an ammonia injection apparatus 640, a mixing section 645, and a selective catalytic reduction element 650 disposed downsteam of the ammonia injection apparatus and adapted for reduction of NOx. The emissions treatment apparatus may be incorporated within a heat recovery steam generator 601.
