Abstract
In a turbine exhaust structure and a gas turbine, a turbine casing () formed in an annular shape to constitute a combustion gas passage A is provided. An exhaust diffuser () formed in an annular shape to constitute a flue gas passage (B) is connected to the turbine casing () to constitute a configuration. By providing a pressure loss body () in the exhaust diffuser (), efficient pressure recovery can be carried out, which improves turbine efficiency, thereby enabling improvement of the performance.
