LINER COOLING STRUCTURE WITH IMPROVED PRESSURE LOSSES AND COMBUSTOR FOR GAS TURBINE HAVING THE SAME

摘要

The disclosed invention relates to a liner cooling structure of a duct assembly including a liner, a transition piece connected thereto, and a flow sleeve surrounding the liner, and compressed air through a transition piece channel consisting of an annular space between the transition piece and the flow sleeve. A first flow path for supplying is formed, and a second flow path for independently supplying compressed air toward the transition piece channel is formed at an acute angle while facing the same direction as the compressed air flow flowing through the first flow channel. It is characterized by being formed.
