Title:
OUTLET SEAL, OUTLET SEAL SET, AND GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2021/049238
Kind Code:
A1
Abstract:
An outlet seal (70o) connects a combustor that combusts a fuel to generate combustion gas and a shroud for a stator. The outlet seal has a gas path surface (72), a first connection section (81), and a second connection section (91). The shape of the gas path surface in a cross section perpendicular to an axis (Ar) is an arc centered on the axis. The first connection section is formed at a first side (Dau) in an axial direction (Da) and is connected to the combustor. The second connection section is formed at a second side (Dad) in the axial direction and is connected to the shroud (53o). The gas path surface has an inclined surface (73) that is inclined with respect to the axis in a cross section including the axis, such that the flow-path area of a combustion-gas flow path (79) is reduced toward the second side (Dad).
