Abstract
An arrangement (100) for delivering combustions gas from a plurality of combustors onto a first row of turbine blades along respective straight gas flow paths, including: a hoop structure (104) at a downstream end of the arrangement and defining at least part of an annular chamber (24); and a plurality of discrete ducts (102), each disposed between a respective combustor and the hoop structure (104). Each duct (102) is secured to the hoop structure (104) at a respective duct joint (116). The hoop structure (104) includes a quantity of hoop segments (105, 130, 132) that is less than a quantity of ducts (102).
Claims16
An arrangement for delivering combustions gas from a plurality of combustors onto a first row of turbine blades along respective straight gas flow paths, comprising:
- a hoop structure at a downstream end of the arrangement and defining at least part of an annular chamber;
- and
- a plurality of discrete ducts, each disposed between a respective combustor and the hoop structure, wherein each duct is secured to the hoop structure at a respective duct joint;
- wherein the hoop structure comprises a quantity of hoop segments that is less than a quantity of ducts.
An arrangement for delivering combustions gas from a plurality of combustors onto a first row of turbine blades along respective straight gas flow paths, comprising:
- an annular structure comprising a radially inner hoop wall and a radially outer hoop wall, the annular structure defining an annular chamber at a downstream end of the arrangement, wherein the inner hoop wall and the outer hoop wall each comprise a quantity of hoop segments that is less than a quantity of combustors, and
- a plurality of discrete ducts, each disposed between a respective combustor and the hoop walls.
An arrangement for delivering combustions gas from a plurality of combustors onto a first row of turbine blades along respective straight gas flow paths, comprising:
- an annular structure defining an annular chamber at a downstream end of the arrangement, the annular structure comprising two or fewer hoop segments;
- and
- a plurality of discrete ducts, each extending from a respective combustor and in fluid communication with the annular structure.
