Abstract: An exhaust hood for a steam turbine includes a bearing cone; an annular flow guide; and an external casing surrounding the bearing cone and the flow guide. Meridional shapes of the flow guide at respective circumferential positions are shapes obtained by rotating one representative shape around an upstream end of the representative shape in a meridional plane and by reducing or maintaining a radial length of the representative shape. A circumferential distribution of inclination angles of an upstream end of the flow guide with respect to a center axis of a turbine rotor of the steam turbine has representative inclination angles at respective representative positions in the circumferential direction. The circumferential distribution between the representative positions is defined by a linear interpolation. Each representative position is a position where the inclination angles change from increasing or decreasing to decreasing or increasing, or from constant to increasing or decreasing.
