Gas turbine engine combustion chamber - has flame-tube wall cooling and angled plates diverting air along wall fitted to combustion air inlets

摘要

The gas turbine plant combustion chamber has annular spaces between the chamber outer casing and one or more internal flame tubes. Compressed air, ducted into these spaces, enters the tubes through primary, secondary and possibly tertiary openings, mainly in the sides, for combustion, and through drillings, slots or the like for film cooling. Angled deflector plates (2) are fitted radially inside the tube wall (1). One leg (3) projects into a combustion air opening (5), separating off a segment (4) for the cooling flow, while the other (6) is radially spaced from and parallel to the wall.
