Abstract
A combuster (2) of a gas turbine engine (1) is fed with gaseous ammonia and that gaseous ammonia is burned to drive a turbine (3). Inside the exhaust passage of the gas turbine engine (1), an NOx selective reduction catalyst (10) is arranged. Inside one or both of the intake passage of the gas turbine engine (1) or the exhaust passage upstream of the NOx selective reduction catalyst (10), ammonia is fed. This ammonia is used to reduce the NOx which is contained in the exhaust gas at the NOx selective reduction catalyst (10).
Claims12
An engine fueled by ammonia which arranges in an exhaust passage of the engine an NOx selective reduction catalyst able to selectively reduce NOx contained in exhaust gas in the presence of ammonia, wherein fuel feeding means for feeding fuel comprised of gaseous ammonia in a combustion chamber of the engine is provided, and ammonia is fed to one or both of an inside of an intake passage of the engine or an inside of an exhaust passage upstream of the NOx selective reduction catalyst so as to reduce the NOx contained in the exhaust gas at the NOx selective reduction catalyst by fed ammonia.
