∙ 15y ago
A convergent-divergent nozzle is generally used in steam turbines. This is because it drives generators in producing electricity with the use of turbine rotors with curved axes.

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 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 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 methods of compounding of steam turbines?
no
What is steam nozzles types of seam nozzles?
1) convergent nozzle 2)divergent nozzle
What type of combustion engine would you classify steam turbines used in power plants?
Steam turbines are external combustion engines.
Fossil fuel plants and nuclear plants both heat water in order to turn?
Steam turbines, which then themselves turn generators.Nearly every method for generating electricity at commercial scales uses turbines at some point (though they may be wind, steam, or water turbines).
Why is excessive moisture in steam undesirable in steam turbines?
moisture present in steam due to quality of steam.
