Free download of : Design And Materials For Modern Steam Turbines With Two Cylinder Design Up To 700 MW
Power plant market requirements have changed in recent years. The tendency for highly flexible and efficient power plants with long revision intervals, life times ≥200 000h as well as lo investment costs have resulted in an increased effort in the improvement of design and materials.
One possible way to meet high efficiency requirements is to install sub-critical steam power plants with live steam temperatures of T ≥565°C and an optimized steam cycle path. As a result, new challenges have arisen for the design of a two cylinder steam turbine line for a capacity up to 700 MW. In addition, the realization of critical turbine components need improved design and materials, which offer all possibilities for a cost effective and flexible service. At the same time, the combined cycle power plant market demands constantly high performance, reliability and operating flexibility at moderate prices for competitive life cycle costs. For this power range,two cylinder designs are also typically applied for the steam turbine …….
