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 is the control stage in steam turbines?
The control stages are the stages at which steam is admitted to or extracted from the turbine. These "control" the output of the turbine.
How many stages of steam turbine rotor?
It depends upon megawatt of turbine & design of blades.
What are stages in steam turbine?
one stage is the combination of one moving blade and fixed blade.
What is a steam turbine diaphragm?
Steam turbine is comprising of stages, number and size of the stages depands upon the break horse power of the turbine. The stage has set of moving and fixed blades. The moving blades are attached to the rotor while the stationary blades is called Diaphragm. The diaphragm guides the steam to glide over the moving blades for producing rotary motion.
How does a steam engine differ from a steam turbine?
Technically a steam turbine is a particular type of steam engine. A classic steam engine usually refers to a reciprocating steam engine, which uses a piston and crank arrangement, where pressurised steam (from the boiler) forces the piston through its stroke, producing output power. A steam turbine produces power with pressurized steam expanding to high velocity, and impinging on turbine blades which produce rotational output power. A steam turbine can be considered similar to a windmill, although steam turbines typicaly rotate much faster, and often have many stages of steam expansion within a single machine.
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 is the function of super heater?
A superheater increases the temperature of the steam for use in a turbine or an engine. Without the additional heat, a multi-stage turbine or engine will get moisture (water) in the lower pressure stages as the steam cools, causing erosion of the blades or cylinders.
How do you decide number of stages for a steam turbine?
It is generally based on the Type of rotor ( Impulse/ curtis) and the enthalpy drop per stage.
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 type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
What is heat rate of steam turbine How to calculate heat rate of steam turbine?
manish
