摘要： An arrangement is disclosed in which deflections and mechanical stresses in turbine low pressure casings are controlled by inserting struts between the turbine diaphragm ledge ring stages. Preferably, the struts are cylindrical in shape, although other different shapes can be used in accordance with the needs of different applications. The struts can be solid or hollow in construction, although preferably they are hollow to reduce the material needed to fabricate them. The struts are located around the turbine casing, as is required to connect together two ledge rings where there is high axial deflection in the casing.

摘要： A steam turbine system for use in a power plant includes a steam seal header that collects steam from seals of a high pressure steam turbine and an intermediate pressure steam turbine. The collected steam is provided to seals of a low pressure steam turbine to ensure the seals provide an effective seal for the low pressure steam turbine. Steam from the low pressure steam turbine is also collected in the steam seal header and it is mixed with the steam collected from the high and intermediate pressure seals. The mixed steam is then provided to drive the low pressure steam turbine.
