| 发明名称 | Premixer assembly for mixing air and fuel for combustion | ||
| 摘要 | A premixer assembly for mixing air and fuel for combustion includes a plurality of tubes disposed at a head end of a combustor assembly. Also included is a tube of the plurality of tubes, the tube including an inlet end and an outlet end. Further included is at least one non-circular portion of the tube extending along a length of the tube, the at least one non-circular portion having a non-circular cross-section, and the tube having a substantially constant cross-sectional area along its length | ||

| 主权项 | 1. A premixer assembly for mixing air and fuel for combustion comprising: a plurality of tubes disposed at a head end of a combustor assembly; a tube of the plurality of tubes, the tube having a longitudinal axis; an inlet portion of the tube having a non-circular cross-section, the non-circular cross-section being perpendicular to the longitudinal axis at the inlet portion; an outlet portion of the tube having a substantially circular cross-section, a cross-sectional area of the tube remaining substantially constant over an entire length of the tube, the cross-sectional area defined by a cross-section of the tube perpendicular to the longitudinal axis at the cross-section; and at least one fuel injection aperture disposed at a fuel injection plane located between an inlet end of the tube and an outlet end of the tube, the non-circular cross-section being perpendicular to the longitudinal axis of the at least one non-circular portion of the tube. | ||
