Engine

摘要

A combustor of a gas turbine engine is fed with liquid ammonia and that liquid ammonia is burned to drive a turbine. Inside the exhaust passage of the gas turbine engine, an NOX selective reduction catalyst is arranged. Inside the intake air which flows into the compressor, liquid ammonia is fed. This liquid ammonia is used to cool the intake air. The NOX which is contained in the exhaust gas is reduced by the unburned ammonia which is exhausted into the exhaust passage by the NOX selective reduction catalyst.

主权项

1. A gas turbine engine comprising:
a compressor; a turbine; a NOx selective reduction catalyst arranged in an exhaust passage of the turbine, wherein the NOx selective reduction catalyst is configured to selectively reduce NOx contained in exhaust gas with unburnt ammonia exhausted into the exhaust passage; a combustor that includes:
a combustion chamber; anda fuel feed device that feeds fuel comprised of liquid ammonia into the combustion chamber with combustion gas in the combustion chamber being fed into the turbine; and an ammonia feed device that feeds liquid ammonia into an intake port of the compressor such that the liquid ammonia fed from the ammonia feed device into the intake port is used to cool air in the turbine, wherein liquid ammonia is made to flow out from at least one of stationary blades or moving blades of the turbine.
