Turbine with a compact inflow casing due to inner control valves

摘要

The turbine has an inflow housing (1), which comprises an inlet for an inflowing working fluid, where the inlet can be closed by a quick closing valve (4), multiple control valves (8,91) and two nozzle groups (21,22). The secondary control valve connects the former nozzle group to the latter nozzle group such that the flow of the working fluid from the former nozzle group into the latter nozzle group can be controlled by the secondary control valve. An independent claim is also included for a method for operating a turbine.
