ABSTRACT:
Apparatus for mixing fuel and air for combustion in a gas turbine engine is disclosed. Various construction details capable of reducing pollutant emissions in the engine exhaust are discussed. In detailed form scoops 20 at the upstream end of the combustion chamber 12 provide uniform flow about the fuel nozzles. Deflectors 26 downstream of the fuel nozzles collimate the scooped air to aerodynamically confine the mixing fuel and air. Premature spreading of the fuel and air before nearly homogeneous fuel-air ratios are achieved is inhibited.
