Abstract
The apparatus is used to clean a stator portion facing a rotor with removable peripheral poles in a turbine-alternator group. The apparatus has an elongated frame, adapted to replace one of the poles of the rotor by means of attachments devised for this purpose. An elongated brushing element extends generally in parallel with respect to the stator portion to be cleaned. Positioning devices are mounted between the frame and the brushing element to position the brushing element so that it comes in contact with the stator portion to be cleaned during the operation of the apparatus. A driving motor is coupled to the brushing element, and injectors are mounted onto the frame to inject a solvent under pressure on the stator portion to be cleaned when the apparatus is in operation. The method consists to turn slowly the rotor equipped with the apparatus to clean the stator portion.
