| Abstract: | The causes for the burning of the thrust bearings of condensing steam turbine in Pucheng Power Plant is discussed. By improving the lubricating oil circuit and the axial thrust correction, the high temperature arising from the heavy load of thrust bearings in unit 2 is solved. The method is applied to No 1 unit to avoid similar troubles and to ensure the safety of the equipment. |
