ABSTRACT:
A gas turbine combustion chamber which has primary, secondary and tertiary combustion zones in flow series has a secondary mixing duct and a tertiary mixing duct. The secondary and tertiary mixing ducts reduce in cross-sectional area from their intakes to their outlet apertures to provide an accelerating flow through the mixing ducts to prevent the formation of recirculating zones. Fuel injectors have fuel discharge apertures downstream of any recirculating zones formed at the intakes. The fuel injectors extend across a major portion of the width of the ducts to effectively subdivide the ducts over at least part of the streamwise length of the ducts. The portions of the fuel injectors within the ducts are oval shaped in cross-section and the portions outside the ducts are aerofoil shaped in cross-section. The fuel injectors reduce in dimension perpendicular to the widthwise direction of the duct.
