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, a rotor with at least one rotor component and at least one working fluid channel for channeling a working fluid for driving the rotor, wherein the working fluid channel is bordered by the stator component and the rotor component, the stator component comprises at least one coolant fluid channel (coolant bore) for cooling the stator component with the aid of a coolant fluid. At least one separation barrier is arranged between the working fluid channel and the coolant fluid channel for separating the coolant fluid channel and the working fluid channel from each other. The turbomachine is characterized in that the separation barrier comprises at least two piston rings. The two piston rings are coaxially arranged to each other defining a piston ring space between the piston rings. The piston ring space is a part of the coolant fluid channel. 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. |
