Can steam power plant work with a compressor instead of condenser and heat pump?

ANSWER:

We want to reduce power consumption by removing condenser and pump and throw the output of turbine direct to boiler and then provide less energy to convert vapors into super heated state. This looks quite possible however it is not the case this is because the output of turbine in mixture of vapors and liquid and we are not able to move mixture from one place to another. This is because cavitation would  occur inside pump or compressor and will lead to damaging of our instrument. So first mixture is converted into liquid then pumped to boiler.

BEARING SELECTION

STEP 1 Load Calculation:

First of all calculate loads on shaft. Major loads are Radial and Axial. Radial load is due to weight where as axial load is due to centrifugal forces during turning a car or due to frictional shear if there is skid steering.
Centrifugal axial load = mv²/r

STEP 2 EQUIVALENT RADIAL LOAD:

We know our shaft size so now we select various bearing from the catalog of inner dia equal to our shaft dia and select one bearing at a time and perform below demonstrated calculations. Now we have to calculate equivalent radial loading by using

F_e=X_iVF_r + Y_iF_a as

Where as corresponding values of X_i and Y_i are calculated from following tables

where as 

_Fa= Axial Force

_Co= Bearing static load catalog rating

V= 1 for inner ring rotating and 1.2 for outer ring rotating

so calculate equivalent radial load on bearing

STEP 3 BEARING LIFE CALCULATION:

After that now we know the RPM of our rotating shaft also we know our application so we know what bearing life we require so to calculate bearing life consult the following graph to calculate bearing life first calculate following factors

C/P = Ratio of Bearing Dynamic load catalog rating to Equivalent Radial load

Along with bearing life we have reliability also shown in the graph. Right most life is of 10% reliability and left is of 99.99% reliability also depicted in the graph.

STEP 4 CONCLUSION:

If the selected bearing providing required bearing life then its fine if not then again perform the similar calculation on the next bearing.

If we are not achieving required life then we can use two bearings instead of one

Can steam power plant work with a compressor instead of condenser and heat pump?

Steam power plant cannot work by replacing condenser and heat pump with a compressor this is because at the outlet of turbine there would be a mixture of steam and water and there is no device which can move a mixture of steam and water from one place to another at same time so either first we have to convert the mixture in vapor state or liquid state. So here in this case mixture is completely converted into water and then pumped to boiler. 

FLUID DENSITY DEPENDANCE MORE ON TEMPRATURE THAN PRESSURE

Density of fluid depends more on temperature than pressure. Mathematical reason is co-efficient of volume of thermal expansion

above equation shows that changing temperature would cause greater volume change and consequently density would be more affected by temperature.

Physical reason is that by changing pressure volume change takes place in one dimension whereas changing temperature would cause volume change in all 3 directions.

IONIZATION ENERGY

IONIZATION ENERGY:-

   The minimum energy required to remove an electron from its gaseous atom to form an ion is called ionization energy and the process is called ionization. For example

ATOMIC SIZES

ATOMIC SIZES:-

    Size of an atom is very important in determining its properties whether physical or chemical properties. Atoms are assumed to be spherical so radii is used to determine there sizes. There are various radii to determine size of an atom depending upon type of compound.

CHEMICAL BOND

CHEMICAL BOND:-

Force which hold together two or more than two or more than two atoms or ions to form a large variety of compounds is known as chemical bond. These forces are responsible for the bonding and shape of molecules as shown in fig 

CHARGING AND DISCHARGING OF A CAPACITOR

CHARGING AND DISCHARGING OF A CAPACITOR:-

Capacitor never charges or discharges alone but at least one resistance is attached with it.

Its charging and discharging behaviours both are not linear (straight line) but it is exponential (curved).

How long a capacitor will take in order to charge or discharge depends on product RC of circuit known as time constant that is the product of resistance (R) and capacitance (C) is constant which is time constant.

ENERGY STORED IN CAPACITOR

ENERGY STORED IN CAPACITOR:-

     We know that capacitor is charge storing device. Its charge storing ability that is capacitance increases in the presence of dielectric medium as explained in the previous topic. Capacitor store its energy inside electric field which can be calculated as follow:                                          

We know that Potential Difference=  Work

                                                     Charge

Or V = Energy

           Charge   

Or Energy = V.Q ----------(i)

ELECTRIC POLARIZATION OF DIELECTRIC

ELECTRIC POLARIZATION OF DIELECTRIC:-

Under the action of an external applied electric field each dipole of dielectric readjust its position in such a way that its positive pole appears close to negative charged plate and negative pole appears closer to
positively charged plate such phenomenon is called electric polarization.
Electric polarization of dielectric increases the capacitance. Reason is given below:

REASON:-

The molecules of the dielectric material are readily polarised by the electric field between the capacitor plates. Polarised molecules have a distorted charge distribution that gives opposite 'ends' of the molecules an opposite charge .. these charge distributions are aligned by the capacitor field and create their own induced electric field.
This induced field is opposite in direction to the original field. As a consequence the net field strength between the plates is reduced as a result V also decrease by the relation (V=ED) hence the capacitance has been increased by the relation (C = Q/V)

CAPACITORS & CAPACITANCE OF PARALLEL PLATE CAPACITOR

CAPACITOR:-

               Capacitor is a charge storing device which consists of two parallel metal plates of same nature, surface area, magnitude of charge on each plate and surface charge density separated by small distance as
shown in fig
Magnitude of charge(Q) stored on each plate is directly proportional to potential difference(V) applied by the battery ie
