Abstract

The importance of steam turbine efficiency has been much highlighted in addition to its reliability with drastic increase in fuel cost. Siemens Power Generation, has improved the overall efficiency and availability of its steam turbine by decreasing the steam flow energy losses in each of the steam turbine components, Since the cost of fuel and materials is largely beyond the control of steam turbine operators, the primary mechanism for realizing savings is in the improvement of turbine efficiency. An innovative program has been developed to appraise, evaluate, and restore steam turbine efficiency without major modifications to components. New turbine seal technology coupled with improved repair methods can enhance efficiency gains. This paper describes improved turbine efficiency and performance.
