Abstract
In a steam turbine having a cross-over duct for delivering steam discharged from an intermediate pressure turbine to low pressure turbines, the intermediate pressure turbine provides two outlets for discharging exhaust steam, the low pressure turbine provides two inlets, and the outlets and the inlets are arranged on the same straight line as viewed from a planar direction. One of the outlets and one of the inlets which are close to each other are connected through a cross-over duct, the other of the outlets and the other of the inlets which are far from each other are connected through another cross-over duct, and the cross-over ducts are arranged to be at two stages in the up-down direction.
