During turning gear operation, the turbine generator bearings are lubricated
by use of either the main bearing oil pump or a separate turning gear oil pump,
depending on size and manufacturer of the turbine generator.

18.104.22.168 Boiler Chemical Boil out. Chemical or acid cleaning is the quickest and most
satisfactory method for the removal of water side deposits. Competent chemical
supervision should be provided, supplemented by consultants on boiler-water and scale
problems during the chemical cleaning process. In general, four steps are required in a
a) The internal heating surfaces are washed with an acid solvent containing
a proper inhibitor to dissolve the deposits completely or partially and to disintegrate
b) Clean water is used to flush out loose deposits, solvent adhering to the
surface, and soluble iron salts. Any corrosive or explosive gases that may have formed
in the unit are displaced.
c) The unit is treated to neutralize and "passivate" the heating surfaces.
The passivation treatment produces a passive surface or forms a very thin protective
film on ferrous surfaces so that formation of "after-rust" on freshly cleaned surfaces
