Patent number: 4131432Abstract: A reducing agent such as ammonia, urea or hydrazine effecting selective reduction reaction with an exhaust gas from a gas turbine is injected into a duct of the turbine along with water, and at the same time compressed air from a compressor for the turbine is jetted in the duct to atomize the reducing agent. An amount of the water is controlled so that the surrounding temperature will be suitable for reduction of nitrogen oxides of the exhaust gas. The atomized reducing agent flowing in the duct is decelerated by silencers disposed in the duct, especially by a particular arrangement thereof, so that the reducing agent will be in good contact with the exhaust gas to sufficiently reduce the nitrogen oxides. Catalyst layers are used according to kinds of the reducing agent. The catalyst layers are disposed in the silencers or at the positions that the silencers are disposed.Type: GrantFiled: February 10, 1977Date of Patent: December 26, 1978Assignee: Hitachi, Ltd.Inventors: Isao Sato, Yoshihiro Uchiyama, Youji Ishibashi, Satoshi Tsukahara, Ryoichiro Oshima, Yukio Hishinuma
