Title
(EN) A SYSTEM FOR INDUCTIVE HEATING OF TURBINE ROTOR DISKS
(FR) SYSTÈME POUR LE CHAUFFAGE PAR INDUCTION DE DISQUES DE ROTORS DE TURBINES
Abstract
(EN)
The invention discloses a turbine rotor with at least one rotor disk. The turbine rotor comprises a heating arrangement for heating at least a part of the rotor disk. The heating arrangement comprises a conductor for conducting electric current. The conductor is positioned such that in presence of the electric current in the conductor, Eddy current is generated in the part of the rotor disk. The electric current is an alternating current. The Eddy currents so generated in the part of the rotor disk results in inductive heating of the part of the rotor disk.
(FR)
L'invention porte sur un rotor de turbine comprenant au moins un disque de rotor. Le rotor de turbine comprend un agencement de chauffage destiné à chauffer au moins une partie du disque de rotor. L'agencement de chauffage comprend un conducteur servant à conduire un courant électrique. Le conducteur est positionné de telle sorte qu'en présence du courant électrique dans le conducteur, un courant de Foucault est engendré dans la partie du disque de rotor. Le courant électrique est un courant alternatif. Les courants de Foucault générés dans la partie du disque de rotor se traduisent par un chauffage par induction de la partie du disque de rotor.
