Air Preheater, Superheater & Reheater simple learning. By Yuvi- Study Point

Hey everyone, today we are going to understand Air preheater, Superheater, and reheater in a simple or easy way.
So, without wasting any time lets get started.

Why air preheater is required?
  • The entire heat of the flue gases cannot be recovered by the help of an economizer. So, air preheater is also required to recover some of the heat through the flue gases.
  • The boilers efficiency is also increased by 1% with the help of air preheater.
{NOTE: If you guys don't know about the economizer then go through this link which is shown below. Because in this lecture video I have properly explained the economizer in a simple way.}

The information about air preheaters?
  • Now, back to the point. The use of air preheater is more economical with pulverized fuel boilers or pulverized coal-fired boilers commonly we called these boilers as industrial or utility boiler.
  • The boilers are used because they generate thermal energy by burning of the pulverized coal.
What is pulverized coal?
  • Pulverized coal is the dust coal or powdered coal and it is as fine as the powder which is used on the face.
  • And this coal is further blown into the firebox. So, this is the working or function which is done in the pulverized fuel boiler. And this boiler is used with the air preheater.
  • This boiler is used because the use of air preheater becomes more economical with this boiler.
Superheaters & Reheaters
  • Superheater converts the wet superheated steam into dry superheated steam.
  • The superheaters and reheaters functioning are to superheat steam to the desired temperature.
  • As the steam which is coming from the boiler has some moisture. So, they remove the last traces of the saturated steam moisture by increasing its temperature sufficiently above the saturation temperature.
  • Last traces means 1% to 2% moisture.

Impulse turbine simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to understand about Impulse turbine. So, without wasting any time lets get started. In an impulse turbine, we are generating power by making the use of high-speed water jet impact. once, we have high-speed water jet, we can use its impact to rotate a turbine. In impulse turbine potential energy of the water is converted into kinetic energy by passing it through a nozzle. Impulse turbine is totally remain dipped in water. We can say that the impulse turbine uses Newton's second law of motion as it totally depends on two main factors i.e, the mass of water which was flowing into the turbine and change in the velocity of the flow coming into the turbine to that of going out of turbine after impact.                                 As with a considerable decrement in the velocity, the mass of water entering into the turbine is same as that of mass coming out of t...

NBFM & WBFM (Narrow band frequency modulation & Wide band frequency modulation) simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to learn about NBFM & WBFM (Narrowband frequency modulation & Wideband frequency modulation) in simple or easy way. So, without wasting any time lets get started. The information about NBFM & WBFM When the spectrum's efficiency is important or it is required then we use NBFM (Narrowband frequency modulation) is used.  But when better signal quality is required or when it is important then we use WBFM (Wideband frequency modulation). The term NBFM is used for those applications where the modulation index is less than or equal to 1. And the term WBFM is used for those applications where the modulation index is greater than or equal to 1. Now, let's see more difference between Narrow band frequency modulation(NBFM) and Wideband frequency modulation(WBFM). The term narrow-band and wide-band refer to the actual radio channel bandwidth. The purpose or advantage of using NBFM (Narrowband frequency modulation) The purpo...

Ohm's law simple learning BY Yuvi - Study Point

Hey guys, have you ever heard about Ohm's law, ok so I will teach you in an easy way. So let's get started. It is the basic rule of electricity and it explains the relationship between voltage, electric current & resistance. Ohm's law states that the electric current which is flowing through a circuit or conductor is directly proportional to the voltage and inversely proportional to the resistance. In other words, if resistance is not changed then the electric current flowing through a conductor will increase with the increase in voltage. And if the voltage is not changed then the electric current which is flowing through a conductor decreases with the increase in resistance.    Ohm's law formulas, V = I * R R = V / I I = V / R Ohm's law states that Resistance (R) of the conductor is constant. [*Note = But research shows that the resistance is directly proportional to the length of the conductor and inversely proportional to the cross-sec...
