INTRODUCTION TO THE FUEL

 FUEL 

While talkin about fuel we often think about petrol, diesel, CNG, LPG, etc these are some of the common fuels which is to be used in our daily life.

 Today we'll talk about fuels so let's begins with very common question what is are fuel ?

so fuels are naturally occuring or manufactured comustible organic substance which is used as the source of heat. any source of heat energy is called as heat.

fuel is a substance which reacts or combines with the oxygen and produces large amount of heat energy which is used as the source of power. production of power is used by the various manufacturing industries to run their mechaneries wether it is also used for the domestic purposes also.

That's why it is defined as any fessionable subestance which reacts to provide energy is known as FUEL. in anothe words fuel is a combustible substance which contains large amount of carbon which provides a huge amount of heat at the time of combustion.

It is a oxidation process with the atoms like as carbon, hydrogen, etc which occures with the liberaation of energy.

try to understand by the reaction given below

1. C + O2 --------> CO2 + energy

2. 2H2 + O2 ------> H2O + energy 

 Above presented reaction are some examples of combustion

in the first equation as you have seen that when a carbon atom is reacted with the oxygen then through this reaction some amount of heat energy has released and this heat is further used as a power source for the various perposes.

In this process some residue is also release which contains large amount of carbon. as in case of above equation CO2 and H2O is the residual part which is preduced at the end of the reaction.

ORIGIN OF THE FUEL :- 

  

Basically it is found in the earth crust, in the deep beds in sea, etc.Besides this it is formed by the depletion of animals as well as many huge trees during the naturel disaster. also it is no renewable source and pollutes the environment at very extreame level.

As predicted over thousend of years above when the disaster occurs at that time many animals and huge trees are deplited and reach to the earth crust and in the earth crust due to the presence of extreame heat and pressure the get's converted in to fuels. but the presence of fossil fuel on the earth is in the limited amount and which is depliting day by day it includes petrol, diesel, coal, etc.

Besides these biodiesel is also a kind of organic fuel but it is renewable fuel which is extracted by vegetable oil and also the combustion of biodiesel is environment friendly.

CHARACTERSTIC OF A GOOD FUEL :- 

Hear we'll discuss some terms and on the basis of these terms we'll study the characterstic of fuel

so, the very first point is,

1. CALORIFIC VALUE :- It is the value which states that the amount of heat is released in one kg of fuel which is to be burened. for a ideal fuel it should be higs if the calerofic value of a fuel is high that means it produce much energy in less amount of fuel

2. MOISTURE CONTENT :- Presence of moisture in fuel decreases the heating value of fuel that's why for a ideal fuel it is required that there is less moisture is presence in the fuel.

3. IGNETION TEMPERATURE :- An ideal fuel requires morderate ignetion temperature so that it can burn smoothly.

4. LOW COST :- A good fuel is required to be economically fesiable and also it should be present in huge amount

5. PORTABLE :- It is required for a good fuel that it is easily portable so that one can easily supply across the region 

6. LESS RESIDUE :- A good fuel should have verry less amount of residue so that after burning of fuel verry less amount of residue is left. also this affects the amount of heat produce in the combustion of fuel.

7.COMBUSTION PRODUCT SHOULD NOT BE HARMFULL :- while burning any fuel it is require that the product of combustion of fuel should not harm the health of the human beings.

8. MORDERATE SPEED OF COMBUSTION :- From a good fuel it is expected that the fuel has morderate rate of combustion means while burning the fuel the heat production is not much less nor it should be too high.

9. SIZE :- In case of solid the size of a good fuel is required to be uniform so that combustion of the fuel is regular but there is no specific shape or size is present for gass and liquid so that it is assumed the supply of these fuel should be regular for the regular combustion.

10. SPONTANIOUS COMBUSTION :- In some cases spontanious combustion of fuels may cause some serious hazards specially in the case of liquid and gassious fuel. 

11. COMBUSTION SHOULD BE CONTROLLABLE :- A good fuel have the property that the combustion of these fuel is easily controllabe so that the combustion process should be started easily and also can be stoped easily.

12. EFFICIENT BURNING :- For a ideal fuel it is required that it'll burn efficiently and also it burns without smoke.

13. STORAGE COST :- For a ideal fuel it is required that the storage cost of fuel is minimum in bulk.

Thankyou have a amazing day.
