2. Calorific Value of Fuel And Methods For Calculation of Calorific Values By J_G_A_S Team

3. Calorific Value The Amount of Energy produced by the complete combustion of a material, Eg : KJ/Kg. The Amount of Energy available of Material from an item of food when digested, mostly from Carbohydrates and Fats By J_G_A_S Team

4. How to Calculate Calorific Value ? The Calorific Value of Fuel is the amount of heat or Energy of H eat or E nergy a F uel G enerates during C omplete C ombus tion It is the Variable of the Heat or Energy Released, which is either Measured in Glass Calorific Value(GOV) or Net Calorific Value(NCV) By J_G_A_S Team

5. Calorific Value Formula Net Calorific = Gross Calorific – Latent heat of Value(NCV) Value(GCV) Water Vapors Gross Calorific = Net Calorific + Latent heat of Value(GCV) Value(NCV) Water Vapors OR By J_G_A_S Team

6. Types of Calorific Value Lower Calorific Value (LCV) Higher Calorific Value (HCV) By J_G_A_S Team

7. What is the Difference between Lower Calorific Value(LCV) & Higher Calorific Value (HCV) Higher calorific value (HCV) is the absolute amount of heat released by unit mass or volume of given fuel after combustion A Lower calorific value (LCV) is the absolute quantity of heat released after burning a unit mass or volume of fuel when side products are allowed to escape. By J_G_A_S Team

8. The calorific value of fuel can be defined as the amount of heat produced by the complete combustion of one unit of any fuel. The unit depends upon the type of fuel; for example, coal is a solid fuel, so it is measured in weight units, whereas we use volume units for any gaseous or liquid fuel. Therefore, the calorific value for them will be measured in Kilocalorie per Kilogram and Kilocalorie per Liter, respectively. What is Calorific Value of Fuel By J_G_A_S Team

9. Fuel Value The Energy Released when 1 gram of material is combusted is called its Fuel Value Compound Fuel Value (KJ/gram) Fats 38 Carbohydrates 17 Proteins 17 By J_G_A_S Team

13. Procedure of “Bomb Calorimeter” Experiment Start the Stirrer and Note Down the Initial Temperature of Water A Known Quality of Fuel Sample is Added in the Crucible Let the Current Pass Through the Crucible and let Fuel Sample to Burn in Presence of Oxygen Heat released During Combustion of Fuel is Taken by Water and hence Temperature of Water Rises Note Final Steady State Temperature of Water By J_G_A_S Team

15. Calorific Value = (m 1 + m 2 ) X ( T c +T 1 –T 2 ) X ( C w /m f ) of Fuel Where m 1 and m 2 are the mass of water in the copper calorimeter and water equivalent of bomb calorimeter respectively m f is the Mass of Fuel Sample Whose Calorific Value is to be Determined T 1 and T 2 are the Final and Initial Temperature of the Water Sample. Tc is Temperatur e Correction for Radiation Losses C w is Specific Heat of Water By J_G_A_S Team

16. By J_G_A_S Team Fuel Calorific Value (kJ/kg)  Cow dung cake 6000-8000 Wood 17000-22000 Coal 25000-33000 Petrol 45000 Kerosene 45000 Diesel 45000 Methane 50000 CNG 50000 LPG 55000 Biogas 35000-40000 Hydrogen 150000 Calorific Value of different Material

17. Practical Application of “Bomb Calorimeter” Bomb Calorimeter is used for the measurement of the Calorific Value of Fuel Oils, Gasoline, Coal, Combustion Waste , Foodstuffs and Building Material etc. A Bomb Calorimeter is also used for Energy B alance study in ecology and Study of Nano-material, Ceramics, Zeolite. The Bomb Calorimeter is Helpful to Study the Thermodynamics of C ommon Combustible Materials By J_G_A_S Team
