When steam contains liquid droplets while doing work at high temperatures, the water droplets can etch metal. To combat this, steam can be superheated or the pressure of the system is reduced.

∙ 11y agoThe common problems associated with the steam turbine include high vibration due to deposition on rotor blades, errosion of casing due to steam condensation at low pressure zone, breakage of blades from roots due to resonance, efficiency loss due to increaed internal clearnaces, high axial displacement & thrust bearing demage due to balance piston labyrinth leakage & rotor bow while turbine is standstill at high temperature.

Why would you not heat the steam coming out of turbine and feedback to turbine?
becouse this steam is use repetdly for the turbine
What is heat rate of steam turbine How to calculate heat rate of steam turbine?
manish
What is positive axial displacement of steam turbine?
axial shift of a steam turbine is the shifting of turbine rotor in the forward and backward direction due to steam thrust on blades of rotor.
What is a steam turbine?
It is an engine.A steam turbine is a heat engine that uses the expansion of steam passing through stationary nozzles and blades on a shaft to turn the shaft. The steam can move through the turbine axially (one end of shaft to the other end), radially (shaft to outer casing), or tangentially (around the outer edges of the turbine wheel). In an impulse turbine, the steam is expanded in nozzles and pushes the blades. In a reaction turbine the steam is expanded in the nozzles AND in the blades, the reaction of the expansion of the steam pushes away from the blades spinning the wheel in the process. The expansion of the steam is necessary to increase its velocity through the turbine.
What is turbine windage protection?
when steam flow blockage occured in steam turbine due to damage of blades/nozzles than steam temperature will increase so protect the turbine from high temperature this protection is introduced.
What the difference between extraction and bleeding in steam turbine?
bleed is amount of steam output from turbine through pipe and exit from final stage of turbine . this bleed enter to feed water heater (low and high) and deaereator to increase unit efficiency or rather bleed is the amount of steam drained out of the steam turbine during the expansion of steam and this rejected heat energy is used to heat the feed water supplied to the boiler...........
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
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.
What is heat rate of steam turbine How to calculate heat rate of steam turbine?
manish
What type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
How does steam turbine works?
Steam or water, it works the reverse of a fan, where the fan pushes air down, the turbine is turned by the steam or water. there's a shaft leading from the turbine to the generator, which produces the electricity
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
Nozzle clearance how to steam turbine?
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
What causes steam turbine governor hunting?
inconsistent load will cause steam turbine hunting.
What is positive axial displacement of steam turbine?
axial shift of a steam turbine is the shifting of turbine rotor in the forward and backward direction due to steam thrust on blades of rotor.
How much power do you get from a steam turbine?
Depends on the turbine
