Abstract
A turbine including a turbine rotor, a turbine casing, a plurality of turbine rotor cascades, a plurality of turbine stator cascades, and a diffuser forming an exhaust gas flow path through which exhaust gas flows from one side in the axial direction toward another side, and which is provided on the other side in the axial direction from a last stage rotor cascade. The diffuser has an inner cylinder, an outer cylinder forming the exhaust gas flow path between the outer cylinder and the inner cylinder, and a strut which connects the inner cylinder and the outer cylinder in the radial direction. The outer cylinder has a first inclined surface extending outward from the inside in the radial direction from an inlet of the exhaust gas flow path toward the other side in the axial direction. The first inclined surface forms an angle of 16° to 24° with the axis.
