steam turbine cold start up list:
as the air passes through adiabatic compression volume shrinks and hence temperature rises
Why extractions are taken out from steam turbine.
Rankine cycle is used in steam turbine
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
You don't start a large turbine cold. Typically, the lubrication system is started, the turning gear is engaged and warming steam (a small amount of steam, not enough to turn the turbine) is admitted to the turbine to warm and initially expand the shaft and casing. If this isn't done, thermal shock from the admission of high pressure superheated steam into the cold turbine could damage it.
steam turbine cold start up list:
When turbine shaft temp is below 100 deg.centi, then rolling of turbine carried out it is called coldrolling wider.

Why extractions are taken out from steam turbine.
becouse this steam is use repetdly for the turbine
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.

why we are maintain vacuum in steam turbine at steam outlet or exhaust side
