触媒付エンジンおよびガスタービン

Engine with catalyst and gas turbine

Abstract

PROBLEM TO BE SOLVED: To provide an engine with catalyst and gas turbine in which a catalytic treatment device separate from the engine or the gas turbine is unnecessitated and a concentration control of waste gas components such as NOx and CO in exhaust gas is easily performed also at the time of a maximum output. SOLUTION: This engine is constituted to burn mixed air of compressed air compressed by a compressor and fuel supplied from a fuel injection valve in a combustor at the poststage of the compressor and to revolve a turbine with the combustion gas. In this case, a waste gas decomposition catalytic layer C is formed to decompose/reduce waste gas components such as NOx and CO in combustion gas, on the full surfaces of a turbine stator blade 13 and a turbine rotor blade 14 at the poststage of the combustor or the full surfaces of the turbine stator blade 13 and the turbine rotor blade 14 and the full surface of the inside of a casing of the turbine.
