Answer / k r kumar ranjan

In modern Steam turbine(say 600 MW) we use lube oil which having a ISO VG 32 grade,That means oil's kinematic viscosity is 32 centistoke,which have the ability to form hydrodynamic layer or wedge or film which acts as lubricating layer between shaft and journal bearing Babbitt material.As we know viscosity X Film velocity/Unit load= C(Bearing Characteristics number) which indicates whether there will be hydrodynamic lubrication or not.So for this reason generally grade-32 or 46 grade oils used not 320.

thermal power plants in steam using inlet of turbine.inlet of turbine pressure and flow is same as boiler feedpump why not use direct to turbine?

DCS marshaling Cabinet Power supply can be replace during plant running time? Answer Yes it is possible. I am talking about the controller and cards power supply modules. They are always redundant and connected through diode so that if one power supply fails the other can take the charge immediately.so it is possible to replace one of them in running plant if the other one is healthy. MY question is how switching done.
