Abstract:
An apparatus for cleaning a stator portion facing a rotor with removable peripheral poles in a turbine-alternator group, comprising:an elongated frame, adapted to replace one of the poles of the rotor;fastening means for fastening the frame onto the rotor in place of said one of the poles of the rotor;an elongated brushing element, extending generally in parallel with respect to the stator portion to be cleaned when the frame is mounted onto the rotor;positioning means mounted between the frame and the brushing element, for positioning the brushing element with respect to the frame so that the brushing element comes in contact with the stator portion to be cleaned when the frame is mounted onto the rotor;a driving motor coupled to the brushing element; andinjection means for injecting a fluid under pressure on the stator portion to be cleaned when the frame is mounted onto the rotor.
