| Abstract: | Today’s power market asks for highly efficient turbines which can operate at a maximum flexibility, achieving a high lifetime and all of this on competitive product investments. In line with the demands for reduction of CO2, the machine efficiencies are continuously increased. To further increase efficiencies, deeper insight into the single components is required to better understand the individual contributions to the overall performance. This work focuses on the measurement of leakages through High Pressure Steam Turbine gland sealing. Gland sealing technologies are frequently in focus of research and development activities. Various concepts were and are still developed and proven to work in test rigs. Typically such test rigs form an idealized environment with ideal manufacturing and low tolerances compared to real plant components. For this work real gland sealing components from a power plant were taken, a test rig developed around them and the different leakage path massflow rates determined. The advantage of using real plant components is i.e. in the real life relevance of the gained results by considering real design manufacturing tolerances, surface qualities etc.. By testing numerous gland segments from manufacturing and installing them in different orders, even statistical relevant information may be gained with respect to the influence of manufacturing on the seal tightness. This work presents the development of a test rig around a real plant gland seal and the tested leakages through the various paths of the tested component. The here gained information enables further development and optimization of advanced sealing technologies. |
