Nozzle clearance how to steam turbine?
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
What are the capacity of Steam Turbines?
The capacity of each steam turbines has more than 530 GW in over 6000 installed units. The steam turbines provide high reliability and sustained high efficiency.
What is different betweeb single stage and multi stage steam turbine?
In a single stage steam turbine the steam is run through a nozzle to give it maximum velocity, thus the blades move at very high speeds, impractical for some applications, and only some of the energy is used, about 85-90%. In multi-stage or compound turbines the steam goes through a nozzle to increase its velocity, then after going through a set of blades, it is run through another nozzle to bring the steam back up to the correct velocity. After multiple stages there is no longer enough pressure left to up the velocity of the steam. This method increases the efficiency of the turbine and also decreases wear on the components caused by the high speed of a single stage.
what is purpose of nozzle in steam turbine?
It sends hot gases from the combustion chamber to the 1st stage turbine blades at the correct angle and 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.
How can expansion take place when steam pass through a nozzle?
When steam passes through a nozzle, it undergoes adiabatic expansion due to the decrease in pressure. This expansion causes the steam to increase in velocity as it exits the nozzle, converting some of its internal energy into kinetic energy. The increase in velocity results in a decrease in pressure and an increase in velocity, which can be harnessed in devices such as turbines.
Nozzle clearance how to steam turbine?
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
How does steam make an object move?
Steam can make an object move through the principle of propulsion. When steam is directed through a nozzle, it creates a force that pushes against the object, causing it to move in the opposite direction. This is commonly seen in steam-powered engines and devices like steam turbines.
What are the capacity of Steam Turbines?
The capacity of each steam turbines has more than 530 GW in over 6000 installed units. The steam turbines provide high reliability and sustained high efficiency.
What is steam nozzles types of seam nozzles?
1) convergent nozzle 2)divergent nozzle
What is the methods of compounding of steam turbines?
no
What type of combustion engine would you classify steam turbines used in power plants?
Steam turbines are external combustion engines.
Why is excessive moisture in steam undesirable in steam turbines?
moisture present in steam due to quality of steam.
What is the conditions of steam velocity while flow through steam nozzle?
Nozzles are designed to increase the steam velocity.
What is the effect of friction on the flow through a steam nozzle?
Friction in a steam nozzle can result in energy losses, reducing the efficiency of the nozzle. Frictional forces can cause pressure drops and decrease the velocity of the steam flow, impacting the overall performance of the system. Proper design and maintenance are essential to minimize frictional losses in steam nozzles.
