Turbine-generator sets usually have 2 bearings for
each major component - high pressure turbine, low pressure turbines, generator - and 1 end
bearing for the exciter. The turbines have an extensive oil system which provides
lubrication for those bearings. This picture at a RBMK facility shows a turbine generator set with a lubricating oil system located in the pit area below the turbine. There are usually a large storage tank, coolers to remove heat from the oil, pumps to circulate the oil, and filters and purifiers to keep the oil clean and free from chemical and particle impurities. |
