Why is condensate polishing unit operated at high pressure in a high pressure thermal power plant?
Perhaps the designers did not think of the advantages of a low pressure CPU. The only add on is the booster pump required downstream of the CPU.
Advantages of LP CPU are aplenty, starting from feasibility of gel resins, affordable pre filtration and improved OBR.
Take a peep into the European and Japanese markerts.

What energy does the steam engine use?
steam engine uses thermal energy to convert water into steam and then uses pressure of steam to move the engine .thus thermal energy into pressure and further pressure into mechanical energy.
How do you set Thermal safety valve?
*A valve thatrelieves pressure due to thermal expansion of liquid* You will see PSV's pressure safety valves on vessels with gas in them. You will see TSV's (Thermal Safety Valves) on pipelines/vessels full of fluid. The fluid in a blocked in pipeline in the sun will expand and quickly increase the pressure in the pipeline. The Thermal safety valve relieves this pressure due to thermal expansion. Essentially TSV's and PSV's Are the same physical device just used for different reasons, and so named differently. To complicate the issue you can also get combined temperature and pressure relief valves. These have two mechanisms 1. Normal spring to hold valve closed until set pressure is reached and valve opens. 2. Wax/oil filled probe, that as it gets to set temperature expands and opens valve. I have not yet seen these valves in the process industry, but there is one on my water heater at home. http://www.rmc.com.au/files/spec_sheets/HT501_1.pdf
Why the temperature and the pressure of gas are decreasing after flowing out from turbine?
The gas (working fluid) having flown through the turbine does some work on the turbine, converting its thermal energy into mechanical work produced by the turbine and coming out as an expanding gas with lower temperature and pressure.
What is function of dearetor in thermal power plant?
A dearetor is used to remove "non-condensable" gases from the condensate return lines (water being returned to the boiler).These gases consist mainly of carbon dioxide and oxygen. These gases are undesirable because of the problems they cause when in contact with steel, such as oxygen pitting and carbonic acid corrosion (carbon dioxide forms carbonic acid when in contact with water and has a detrimental effect on steel).Another reason why non-condensable gases need to be removed is that they degrade heat transfers in the system by acting as thermal insulators.
How do you effect the gas turbine exhaust pressure loss on performance?
Gas turbine exhaust pressure loss negatively impacts performance by reducing the effective pressure ratio across the turbine. This loss can lead to decreased power output and efficiency, as the turbine has to work harder to achieve the same thrust or energy output. Additionally, higher exhaust pressure can result in increased back pressure, potentially affecting the overall system's thermal efficiency and contributing to higher fuel consumption. Managing exhaust pressure losses through design optimizations and control systems is crucial for enhancing turbine performance.
What is bleeding of steam in thermal power plant?
Bleeding of steam means Extracting steam from Turbines for heating the feed-water. Normally, there are High Pressure Heaters & Low Pressure heaters in Condensate cycle. Steam bleed out from the turbine gets into these heaters and heats up the feed-water (generally termed as Sensible Heat Addition). The steam that was bled can be re-used as condensate in Deaerators. Steam Extractions although reduce net work output but helps in overall gain in efficiency in terms of Reduced Fuel Consumption.
What the pressure of steam on the turbine blade in any thermal plant?

How does degeneracy pressure differ from thermal pressure in terms of their effects on the stability and behavior of a stellar object?
Degeneracy pressure and thermal pressure are two forces that support stellar objects against gravitational collapse. Degeneracy pressure arises from the quantum mechanical properties of particles, while thermal pressure comes from the temperature of the object. Degeneracy pressure is independent of temperature and increases as the object's mass increases, leading to stability in massive stars. Thermal pressure, on the other hand, depends on temperature and tends to decrease as the object cools, potentially leading to instability. In summary, degeneracy pressure is more important for the stability of massive stars, while thermal pressure is more significant for lower-mass stars.
What eventually causes a thermal dissipate?
The air pressure
Does air pressure eventually cause a thermal to dissipate?
Air pressure itself does not cause a thermal to dissipate. However, changes in air pressure can affect the movement of air molecules and impact the distribution of heat in a thermal system. This can lead to changes in temperature gradients and affect the dissipation of heat.
What is thermal expansion feed water regulator operated by?
They work when steam and water occupy a tube that is on a slight incline. As water level drops the steam space inside the tube expands. The expanding tube is connected to a linkage which will open the water valve as more steam occupies the tube than water.
How thermal expansion affect pressure regulator?
Thermal expansion can affect the performance of a pressure regulator by changing the volume of the fluid inside the regulator as the temperature increases or decreases. This change in volume can impact the pressure setting and accuracy of the regulator, leading to potential fluctuations in the output pressure. It is important to consider thermal expansion effects when designing or selecting a pressure regulator for a specific application.
Largest power plant in India?
The Mundra Thermal Power Station, in the Kutch district of Gujarat, is currently the largest operating thermal power plant in India. It is owned and operated by Adani Power.
Is a battery operated flashlight an example of thermal or electrical energy?
Clearly the bulb itself operates on electrical energy, but this is produced by the battery from chemical energy. I don't see any connection with thermal.
What energy does the steam engine use?

What causes a thermal high near the surface?
High pressure at the surface
What is hotwell in thermal power plant?
A hotwell in a thermal power plant is a reservoir or tank that collects condensate from the turbine exhaust steam and other feedwater sources. It helps in recovering and recycling the steam condensate to maintain efficient water circulation in the power plant's boiler system. The hotwell also serves as a storage tank to supply feedwater to the boiler as needed.
