ABSTRACT:
A steam turbine having improved stationary parts in which a moisture removal slot is formed in a blade ring cylinder immediately upstream of the last row of rotating blades. The slot has a reduced width inlet throat portion and an enlarged manifold portion. The manifold portion of the slot distributes the moisture collected to a plurality of radially oriented discharge holes formed in the blade ring. The inlet throat serves to insolate the manifold from the swirling steam flowing through the turbine, thereby preventing entrainment of the moisture droplets into the steam flow. The blade ring encircles the tips of the last row of rotating blades and the outer flow guide is integrally formed on the blade ring. The steam turbine also has a new inner flow guide that matches a new last row of rotating blades. The new inner flow guide is attached to the existing inner flow guide by welds.
