1. Origin- : Weende experimental station Germany 1865 Henneberg & Stohmann 1865 Ad. 1 Proximate Analysis-:

2. Home- :for use Heat & Cooking. Transportation -: Steam Engines. Heavy Industries-: Metal Works. Electricity-: Power Plant. Coal Application 2

3. Analysis of Coal Sample is required to access the quality of Coal -: There are two type’s of coal Analysis-: Proximate analysis of Coal Ultimate analysis of Coal Need for Analysis of Coal-: 3

4. Evaluation of the Yield of various products obtained upon heating under controlled condition. In deterring the Performance of any Thermo Chemical conversion Process. Volatile Matter Fixed Carbon Content Amount of Ash Proximate Analysis-: 4 Meaning Important Used to Determine the

5. Excess of Moisture is undesirable in coal. It Lowers the effective calorific value of the coal. Presence of Moisture Quenches the fire in the furnace. Presence of Moisture increases the transport cost & cause difficulty in heating. Importance of Proximate Analysis- : 5

6. TM-: Total Moisture FC-: Fixed Carbon SM-: Surface Moisture RM-: Room Moisture IM-: Internal Moisture VM-: Volatile Matter BA-: Bottom Ash FA-: Fly Ash Proximate Analysis of Coal 6

7. Initial Weight- Final Weight X100 SM = Volume of Sample Initial Weight- Final Weight X100 RM = Volume of Sample Proximate Analysis of Coal-: 7

8. 100-SM TM = X RM + SM 100 Initial Weight- Final Weight X100 I M = Volume of Sample

9. Initial Weight- Final Weight X100 VM = - IM Volume of Sample Final Weight- Starting Weight X100 ASH = Volume of Sample

10. Initial Weight- Final Weight X100 BA = Volume of Sample Initial Weight- Final Weight X100 FA= Volume of Sample

11. FC = 100- (IM+ASH+VM) Thankyou for your time & Consecration
