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 turbine rated speed and What is maximum speed rise of steam turbine?
Turbine rated speed varies mainaly on the factors of Generating frequency and means of coupling to generator (viz trough a gear box or directly coupled and no.poles in generator). For exmple a 50hz generting frequency and a bi-pole genarator the turbine speed is 3000RPM. The allowed speed rise also depends on turbine design and generator operational range. Generaly the speed rise is restricted to Maximum of 10% of the rated speed.
Who establishes mandatory replacement times for critical components of turbine engines?
Usually the manufacturer
What do you mean by whirl velocity of turbine?
Whirl velocity of a turbine is determined by how fast the turbine can turn when it is moving. This is a factor considered with airplane manufacturing. Whirl velocity is the number of times in a second that a turbine can rotate, moving at a given speed.
What is the uses of packing steam in turbine?
The main uses for packing steam in a turbine are to produce electricity and power. The steam creates pressure when in turn spins a turbine at very high rates of speed.
What is second critical speed of turbine?
Critical speed means where natural frequency is equal to system frequency.
What is critical speed of steam turbin?
Answer:Turbine shaft material has its own natural frequency, when turbine rotates on such a speed that frequency of shaft become close to its natural frequency, machine causes noise & high vibrations because of resonance due to matching of frequency. Running of Steam "TURBINE" on this speed is avoided & this is called Critical speed. A turbine may have more then one critical speed, which may depend upon number of couplings.A second critical speed is when the Turbine blade tips approach the speed of sound. This effectively limits the speed of a turbine and explains why power plants tend to have turbines of the same capacity.Critical speed of the turbine is the rotor speed at which natural frequency of the assembled rotor (rotor shaft with discs, blades, shrouding strips etc in assembled condition) becomes equal to the operating speed. This is usually a expressed as a range (critical speed range).There are multiple critical speeds. However, the operating speed of the turbine may be above or below the first / lowest critical speed. Accordingly it is called as a flexible or a rigid rotor.Venkatesh
What does self-sustaining speed in a gas turbine Mean?
Self-sustaining speed in a gas turbine refers to the operational condition where the turbine can generate enough thrust and power to maintain its own rotational speed without external assistance. At this point, the energy produced from the combustion process matches the energy losses due to friction and other factors, enabling the turbine to operate efficiently. Achieving self-sustaining speed is critical for the turbine to transition from startup to stable operation.
What is idle speed of turbine?
warm up speed of turbine,andthe minimum speed of turbine before loading is called idle speed.
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 Runaway Speed of hydraulic Turbine and how it is calculated?
The runaway speed of a water turbine is its speed at full flow, and no shaft load. The turbine will be designed to survive the mechanical forces of this speed. The manufacturer will supply the runaway speed rating.
In a wind turbine - does increasing the blade length or decreasing the blade length increases the speed of the turbine?
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
What is speed ratio of turbines?
The speed ratio of turbines refers to the ratio of the rotational speed of the turbine rotor to the rotational speed of the turbine shaft. This ratio is important for defining the mechanical performance and efficiency of the turbine.
Why is the runaway speed of a hydraulic turbine always kept twice its normal speed?
The runaway speed of a hydraulic turbine is the speed at which the turbine coupled to the generator runs at the maximum possible speed due to loss of load and this happens until the shut off valves completely closes the discharge from the penstock. the runaway speed of the turbine is determined by the turbine designer and is influenced by the maximum discharge of water from the penstock, the combined inertia of the turbine runner and the generator and the flywheel. this factor can vary from 1.5 up to 3 times the nominal speed of the turbine and is determined by the turbine designer considering all the load parameters.
What is the self-sustaining speed of gas turbine?
self sustaining speed is output of a turbine= input into compressor
Where is the turbine speed sensor on a 2001kia rio?
Where is the turbine speed sensor on a 2001kia rio with automatic transmission
Where is the turbine shaft speed sensor on a 1996 Ford Ranger?
This engine has no turbine or turbo. Although the 1996 Ford Ranger does not have a turbine or turbo, it does have a turbine shaft speed (TSS) sensor. It is located inside the automatic transmission.
