1. Low vacuum at high loads
2. High HRH temp
3.High steam flow
4. high gland steam temperature
There has to be a built in expansion chamber or release valve. Otherwise the expansion would cause an explosion.
inconsistent load will cause steam turbine hunting.
Expansion and contraction can cause things to crack, as in the weathering of rock. They can cause a bi-metal strip to bend and straighten, which phenomenon is used in some thermostats. Expansion can cause the roadway of a bridge to buckle, so gaps have to be left. Obviously they cause the thread in a liquid-in-glass thermometer to get longer and shorter.
High displacement in a steam turbine typically results from the design and operational parameters of the turbine, including the size and number of stages, as well as the steam flow rate. Increased steam flow leads to a larger volume of steam passing through the turbine, which can elevate displacement. Additionally, factors such as changes in steam pressure and temperature can affect the turbine's efficiency and capacity, potentially causing higher displacement. Proper design and operational adjustments are crucial to manage displacement effectively.
If,clamp is not proper fitted in control oil line that time it may happen cause in control oil line pressure also more than main oil pump disch.

The increase in volume that results from an increase in temperature is called thermal expansion. This occurs because temperature changes cause the particles in a substance to move faster and spread out, leading to an increase in volume.
yes it will be big damages for both that's y fixing differential protection relay between both
The temperature contrasts would cause differential expansion of the bottle which, being brittle, would cause the glass to crack.
An increase in total expenditures affect the nation's economy would cause an expansion.
The force that causes the expansion of hydrogen is thermal energy. As the temperature of the hydrogen gas increases, the molecules move faster and spread out, leading to an increase in volume.
Increases If the gap can easily be conceived as a small break in a metal ring, then the expansion of the metal ring may decrease the gap size.
turbines spin when there is a cause of wind..!!
inconsistent load will cause steam turbine hunting.
Yes, heat gain causes objects to expand due to the increase in thermal energy. As temperature rises, the particles within the object move faster and further apart, leading to an expansion in volume. This is known as thermal expansion.
Heat causes expansion because it increases the speed at which particles vibrate within a substance, creating more space between them. This increased movement and spacing of particles lead to an overall expansion of the substance.
There are several causes that can cause a generator turbine system to lose power. The most common cause is a lack of fuel.
