Method for reducing water drop erosion in steam turbines by controlling the drop size and corresponding steam turbine

摘要

in steam, the condensation in the steam flow primu00e4rtropfen water, partly to the vanes is deposited. continue to arise in and behind the guide vanes sekundu00e4rtropfen, a substantially larger volume than the primu00e4rtropfen.according to the invention by electric fields to the vanes, the size of the sekundu00e4rtropfen tropfenabriss at the trailing edge of the vanes at least reduced the electrostatic forces, and due to a premature demolition of the water drops and thus to a red uzierten sekundu00e4rtropfengru00f6u00dfe.in the steam turbine, the guide vanes, on the one hand, and subsequent laufschaufel, on the other hand, by the turbine blades which has electrodes formed by running and guide vanes at different electric potential legbar.
