This paper reports that technology, uprating, and steam-path degradation reversal can extend the life and boost the efficiency of aging turbines. With the advent of modern machine tool technology, plus extensive R and D efforts, designers could apply improved bucket designs like the laminar flow design. Today's technology is represented by the Schlict design, which minimizes flow separations and boundary layer losses. Schlict buckets can be retrofitted in most designs as long as the diaphragm is also replaced. Adoption of steam-path design advance developed for new units and degradation reversal are the two areas of greatest opportunity in efficiency improvement of aging steam turbine-generators.
