IT is not accurately 535 c.... The water should be in the super heated condition... So we go to like a higher temperature region and also higher pressure region to change the steam as super heated steam and then the steam is allowed to expand in the steam turbine... now the power gained is much higher than the water flowes at saturated condition like (200 c - 300 c )... so only we are moving to higher temperature and higher pressure region

What to do about turbine rotor differential expansion?
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
Why extraction taken from steam turbine?
Why extractions are taken out from steam turbine.
What is steam turbine governor valve?
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.
What type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
Nozzle clearance how to steam turbine?
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
Why you are maintain the vacuum in steam turbine explain me briefly?
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
Why you maintain gland steam temp in steam turbine power plant?
gland steam temp should be nearer to less than turbine lub. oil flash point.
What to do about turbine rotor differential expansion?
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
Water becomes steam at what degrees?
100 degree Celsius
What is hunting in steam turbines?
When the steam turbine can not maintain its selected or designed speed.Type your answer here... Speed fluctuating from low to high speed continously.
How a generator operated by boiler?
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'
Why extraction taken from steam turbine?
Why extractions are taken out from steam turbine.
Why would you not heat the steam coming out of turbine and feedback to turbine?
becouse this steam is use repetdly for the turbine
How much heat energy is needed to change 10 kg of water at 50 degree celsius to steam at 120 degree celsius?
4.2 × 105 J
Where exactaly located thrust bearing in steam turbine?
Thrust bearings are mounted on turbines at or near the end of the shaft, closest to the steam chest (or inlet). This is to maintain the shaft in position with the casing of the turbine, allowing the casing and the shaft to expand evenly together toward the drive end of the turbine.

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.

What are the preventive maintenance of steam turbine?
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.
