No, a steam turbine should not be operated at low loadings. This will only utilize the tips of the blades, causing twist that is outside of design parameters. You can operate this way, but the time you can do so is limited.
STEAM TURBINE is a machine for generating mechanical power in rotary motion from the energy of steam at temperature and pressure above that of an available sink. A turbine operated by highly pressurized steam directed against vanes on a rotor.HEAT ENGINE is a physical or theoretical device that converts thermal anergy to mechnical out put.....it converts heat energy into work.
gland steam temp should be nearer to less than turbine lub. oil flash point.
The boiler heats water into steam. The steam is pressurized and fed into a turbine which causes it to rotate. As the steam turbine rotates, the connected generator rotates and produces electricity. Make Sense??? Please 'Recommend Contributor'
In large turbines, a valve controls steam flow to groups of nozzles. The number of open valves controls the number of nozzles in use according to the load. A bar-lift or cam arrangement operated by the governor opens and closes these valves in sequence. Such a device is a multi-port valve. Using nozzles at full steam pressure is more efficient than throttling the steam.

Why extractions are taken out from steam turbine.
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.

Rankine cycle is used in steam turbine
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
