Steam Turbine overhauling is very important to run turbine continuously
with maximum efficiency.
Overhauling of steam turbine is the major thing that we need to do every
year within the scheduled time.
In overhauling firstly we need to consider major overhauls like detailed
inspection and overhaul of the entire steam turbine generator set including
the turbine casing rotor, seals, bearings, the generator, and auxiliaries such
as the gear, couplings, lubrication system, and controls
