STRUCTURE OF EXHAUST SECTION OF GAS TURBINE AND GAS TURBINE |
摘要 |
There is provided an exhaust section of a gas turbine and a gas turbine that can cool a strut and the periphery of a bearing without decreasing the efficiency of the gas turbine. A structure of an exhaust section of a gas turbine has: a casing in which a gas path part is formed; a bearing part that rotatably supports moving blades of a turbine section; a strut that extends inwardly from the casing and supports the bearing part; an opening formed in the casing; and a cooling flow channel that extends from the opening toward the bearing part along the strut to guide air at a lower temperature than an exhaust gas flowing in the gas path part to the gas path part and opens into the gas path part at a position downstream of a last-stage moving blade of the turbine section.
