HOT GAS PATH DUCT FOR A COMBUSTOR OF A GAS TURBINE

摘要

A hot gas path duct or unibody liner for a gas turbine includes a main body having a forward end and an aft end. The main body defines a cross-sectional flow area and an axial flow length that extends between the forward end and the aft end. The main body further defines a fuel injection portion disposed downstream from the forward end and upstream from the aft end. The cross-sectional flow area decreases along the axial flow length between the forward end and the fuel injection portion and increases along at least a portion of the axial flow length downstream from the fuel injection portion.

1. A unibody liner, comprising:
a. a main body having a forward end and an aft end, the main body defining a cross-sectional flow area and an axial flow length that is defined between the forward end and the aft end, the main body further defining a fuel injection portion disposed downstream from the forward end and upstream from the aft end; and b. wherein the cross-sectional flow area decreases along the axial flow length between the forward end and the fuel injection portion and increases along at least a portion of the axial flow length downstream from the fuel injection portion.
