Guiding device in a diffuser flow passage of a turbomachine and method of operation

摘要

The diverting mechanism has a guide vane (9) with an incident flow edge and a departure flow edge, between which a deflection surface is provided that deflects a flowing medium from the incident direction. The guide vane is adjustable in respect of the profile of its deflection surface relative to the direction of incidence. The deflection surface is rotatable and adjustable in its outer shape. Independent claims are also included for the following: (a) a steam turbine with a diverting mechanism (b) a gas turbine with a diverting mechanism (c) a turbocompressor with a diverting mechanism (d) and a method of altering a diverting mechanism in a diffuser.
