Which device controls the speed of the turbine shaft?
The device which control the speed of Turbine is Governor. The Governing system sense the speed of shaft & regulate the Fuel/ Motive fluid flow to the Turbine to maintain the set shaft speed.
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.
What is actuator in turbine?
Which actually Actuates the Steam Control Valve
What is a reaction steam turbine?
Steam turbine is when a device that has the extract thermal energy from pressurized steam. It is used to do mechanical work on a rotating output shaft. The steam turbine was invented by Sir Charles Parsons in 1884.
What is the length of an blade for a gas turbine?
The length of a blade depends on the style (impulse or reaction), the overall size of the turbine, whether it is an axial flow or radial flow turbine, and where the blade is located within turbine of an axial flow turbine. One thing that is constant: the length of the blade increases from the steam or gas inlet to the discharge of the unit. The profile will gradually increase in diameter from inlet to discharge.
Which device controls the speed of the turbine shaft?
The device which control the speed of Turbine is Governor. The Governing system sense the speed of shaft & regulate the Fuel/ Motive fluid flow to the Turbine to maintain the set shaft speed.
What is governing of impulse turbine?
Basically governing of a turbine is controlling the speed of the turbine as the load keeps varying. The turbine needs to rotate at a constant speed. The governing of an impulse turbine is done by varying the jet of water that hits the buckets of the runner. This is done by using a spear arrangement in the pen stock. A pen stock is a type of pipe that provides the jet of water.

How steam turbines be classified?
1) Impulse turbine 2) reaction turbine
What are the two basic types of steam turbines?
impulsive turbine reaction turbine

What du you understand by the term governing of steam engine?
A governor is a speed control device. It can be mechanical, hydraulic, pneumatic or electronic. It maintains a specific speed of rotation of the flywheel of the engine, or the shaft of a turbine, which is set by the operator. Governing an engine is just that, controlling the speed of the engine.
What is a advantages and disadvantages of Francis turbine?
The inward flow reaction turbine having radial discharge at outlet is called Francis turbine
Comparison between impulse and reaction turbines?
in the case of impule turbine total energy at inlet is kinetic energy and in case reaction turbine energy at inlet is kinetic and pressure......
What is the equation of reaction turbine?
Torque=pQ(Vt1R1 - Vt2r2)
What type of blades Parson's reaction turbine has?
only moving blades
What is steam velocity in turbine?
That is how fast the steam is actually moving in the turbine. For impulse turbines it is twice as fast as the turbine blades. In reaction turbines it is the same speed as the blades. Because the blades of a turbine cannot move faster than 4500 feet per second without self destructing as it overcomes the centripetal force of the turbine wheels, the steam turbine is designed such that no turbine will exceed more than ~1150 feet per second on its tip speed. Thus the steam velocity through the turbine will be less than ~1150 fps for a reaction turbine and less than ~2300 fps for an impulse turbine, or about ~1570 mph, more than twice the speed of sound.
