Abstract
Provided is an ammonia injection device () installed at an exhaust gas duct through which an exhaust gas generated in a gas turbine flows, and configured to inject ammonia into the exhaust gas at an upstream side of a denitration catalyst configured to perform denitration processing in a flowing direction of the exhaust gas, the device including a plurality of ammonia injection pipes () disposed in parallel each other in a surface which traverses the exhaust gas duct. A plurality of nozzle pipes () configured to eject the ammonia from the ammonia injection pipes in an arrangement direction of the plurality of ammonia injection pipes are installed at the ammonia injection pipe in a longitudinal direction of the ammonia injection pipes. Diffuser panels () extending toward a downstream side in a flowing direction of the exhaust gas at both sides in a longitudinal direction of the ammonia injection pipes with respect to the nozzle pipes are formed at the nozzle pipes. The ammonia injection device can contribute to a compact exhaust gas denitration system.
