Abstract
In the steam turbine for power generation, both higher performance and reliability are required. Although the steam turbine key technologies are recently developed by CFD analyses and the experiments, the final verification of them in an actual plant machine is still important. However, it takes much long time for this verification and feedback the results to design processes. Therefore, it is strongly desired to minimize this step. To solve the problem, Toshiba Corporation planned to construct the actual size steam turbine test facility, which was successfully completed and started the operation. The HP turbine has 16 stages, which are supposed to be applied for advanced turbine in the very near future. The LP turbine consists of 6 newly developed stages, including a series of 60Hz35inch last three stages. The first performance test was successfully conducted and both HP and LP turbines showed as good enough efficiency as their design requirement.
