Abstract: PROBLEM TO BE SOLVED: To heighten the efficiency of a low pressure steam turbine connected to a condenser and reduce its manufacturing cost by setting a divided plane between an upper part and a lower part of an outer casing to the height of an axis of a turbine rotor, and making the concrete foundation reach the divided plane. SOLUTION: A divided plane 8 between an upper part 6 and a lower part 7 of an outer casing is positioned at the height of an axis 9 of a turbine rotor 4, and the concrete foundation 14 reaches the divided plane 8. The lower part 7 of the outer casing 1 and a support place 10 of the turbine rotor 4 are fixed to the concrete foundation 14. The outer casing 1 is opened on at least one side horizontally at a right angle to the axis 9 of the turbine rotor 4, and a condenser is connected to an opening. The upper part 6 is formed of an assembled hood 19 and a frame part, and the frame part is connected to the condenser and the lower part 7. The hood 19 is connected to the lower part 7 and the frame part, and the frame part is disposed between the condenser and the hood 19.
