Turbomachine for generating power having a temperature measurement device in a region of the rotor

Abstract

A turbomachine having a rotor is provided, wherein the rotor comprises a central holding element and rotor elements which are arranged thereon, is intended to permit faster start-up without reducing the lifetime of the rotor, while permitting better predictions relating to the remaining lifetime of the rotor. To this end, a contact element is arranged in a region of the rotor between the holding element and the rotor element, wherein the contact element comprises a temperature measurement device.

1 . A turbomachine for generating power, comprising:
 a rotor, wherein the rotor comprises a central retaining element in the form of a tie rod and rotor elements in the form of rotor disks arranged thereon, wherein a contact element is arranged in a region of the rotor between the central retaining element and the rotor element, wherein the contact element comprises a temperature measurement device.   
     
     
         2 . The turbomachine as claimed in  claim 1 , wherein said region of the rotor is the region which is subjected to the highest thermal loads in comparison to other regions. 
     
     
         3 . The turbomachine as claimed in  claim 1 , wherein the contact element is mounted rotatably on an axle, wherein the axle is attached to the central retaining element. 
     
     
         4 . The turbomachine as claimed in  claim 1 , wherein the contact element comprises a thermally conductive material on its side facing the rotor element. 
     
     
         5 . The turbomachine as claimed in  claim 1 , wherein the contact element comprises an insulating material on its side facing the central retaining element. 
     
     
         6 . The turbomachine as claimed in  claim 1 , wherein in the region of a bearing assigned to the central retaining element, the central retaining element comprises a transmitter connected to the temperature measurement device on a data side of the device, wherein said transmitter transmits temperature data. 
     
     
         7 . The turbomachine as claimed in  claim 1 , wherein a plurality of contact elements is arranged symmetrically about the central retaining element. 
     
     
         8 . The turbomachine as claimed in  claim 1 , wherein said turbomachine is configured as a gas turbine. 
     
     
         9 . A power plant comprising a turbomachine as claimed in  claim 1 .
