PROBLEM TO BE SOLVED: To provide a denitrification processing apparatus and method for performing denitrification processing on high-temperature exhaust gas of a gas turbine in which an exhaust heat recovery boiler is not installed.SOLUTION: In a denitrification apparatus for high-temperature exhaust gas, a denitrification reactor 4 for ammonia catalytic reduction, an air fan 6 for cooling exhaust gas by introducing air to a front flow side of the denitrification reactor 4 and a mixing foil 1 as a mixer for mixing air introduced into a gas turbine exhaust gas duct 12 by the air fan 6 with exhaust gas are disposed in the exhaust gas duct 12. A check damper 8 for high-temperature exhaust gas back flow prevention is disposed in the exhaust gas duct at a front flow side of the mixing foil 1, and a seal air fan 7 for blowing air for sealing is provided between the check damper 8 and the mixing foil 1. |
