Show and label the components of the Hayward-Tyler-Terry steam turbine?
The Hayward-Tyler-Terry steam turbine consists of several key components: the rotor, which houses the blades that convert steam energy into mechanical energy; the stator, which contains stationary blades that guide the steam flow; the nozzle, where steam expands and accelerates before entering the rotor; and the bearings, which support the rotor and allow it to spin. Additionally, the casing encloses the turbine, maintaining pressure and directing steam flow. Together, these components work to efficiently convert thermal energy from steam into rotational energy.
How does a desupeheater cool superheated steam?
A desuperheater cools superheated steam by introducing a cooling medium, typically water, into the steam flow. As the water sprays or mixes with the steam, it absorbs heat, causing the steam's temperature to decrease. This process often involves heat exchange and can efficiently bring the steam down to a desired saturation temperature without condensing it entirely. The result is cooler, lower-energy steam suitable for various applications.
Why Fuel consumption varying when the generator load varies?
with decrease in fuel consumption the amount of steam produced is also reduced.Hence when lower quantity of steam passes through the turbine the torque generated is less and since generator and turbine are coupled on a single shaft the generator torque also decrease which reduces load.
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.
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.
Nozzle clearance how to steam turbine?
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
What is steam nozzles types of seam nozzles?
1) convergent nozzle 2)divergent nozzle
What is the conditions of steam velocity while flow through steam nozzle?
Nozzles are designed to increase the steam velocity.
How pressure of steam decreases while flowing in a nozzle?
yes
In divergent nozzle pressure will increase or decrease?
In a divergent nozzle, pressure will decrease as the flow area increases. This is due to the conservation of mass principle, where an increase in area causes a decrease in velocity and thus a decrease in pressure according to Bernoulli's equation.
Why is convergent-divergent nozzle generally used in steam turbines?
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.
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

How will heat transfer affect the fluid velocity at the nozzle exit?
Heat transfer can affect the fluid density at the nozzle exit, which in turn can impact the fluid velocity. An increase in heat transfer can lower the fluid density, resulting in an increase in velocity at the nozzle exit due to conservation of mass. Conversely, a decrease in heat transfer can raise the fluid density, leading to a decrease in velocity.
