| 摘要 |
A power generating apparatus including a gas turbine engine 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). An emissions treatment apparatus includes in the exhaust gas flowpath a CO oxidation catalyst disposed at a location with an exhaust gas temperature for which the CO oxidation catalyst advantageously limits NO2 production. The emissions treatment apparatus further includes an ammonia injection apparatus, a mixing section, and a selective catalytic reduction element disposed downsteam of the ammonia injection apparatus and adapted for reduction of NOx.
