TURBOMACHINE WITH AN INGESTION SHIELD AND USE OF THE TURBOMACHINE

摘要

Subject matter of the invention is a turbomachine as well as a use of the turbomachine. The turbomachine, for instance a gas turbine or a steam turbine, comprises a stator with at least one stator component (stator ring), a rotor with at least one rotor component (rotor shaft) and at least one working fluid channel for channeling a working fluid (hot combustion gas or supercritical steam) for driving the rotor. The working fluid channel is bordered by the stator component and the rotor component. The turbomachine is characterized in that at least one heat shield (ingestion shield) is located in the working fluid channel for protecting the stator component from an erosive attack of the working fluid. The ingestion shield is preferably a consumable made of stainless steel. The turbomachine is used for producing electricity by leading the working fluid to rotor blades of the rotor (coupled to a generator) through the working fluid channel.
