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.

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 are the thermal parameters?
the basic thermal parameter are pressure(P), volume(V), and temprature(T).
What the pressure of steam on the turbine blade in any thermal plant?
Its not possible the same pressure in every thermal pp turbines very Pressure each capacity of turbine according to design.kachin panchal
What eventually causes a thermal to dissipate?
The air pressure
What eventually causes a thermal dissipate?
The air pressure
How does thermal energy contribute to condensation?
lack of thermal energy or excess pressure (or both) will contribute to condensation.
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.
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 are the three agents of metamorphism?
heat, pressure, and hydro-thermal solutions
What causes a thermal high near the surface?
High pressure at the surface
Which variable is held constant when testing for the thermal expansion relationship of a gas?
pressure
