Study Notes

Proximate Analysis of Coal

Four products separated in proximate analysis: Moisture, Ash, Volatile Matter, Fixed Carbon.
FC (Fixed Carbon) represents the solid combustible residue left after volatile matter is released, indicating the carbon content of the coal.
Main function of proximate analysis: To evaluate coal's combustion characteristics and efficiency in energy production.

Volatile Matter and Nonvolatile Fraction

Nonvolatile fraction of coal consists of Fixed Carbon and Ash, representing the components that remain after combustion.
Routine determination of volatile matter does not separate and report the specific amounts of Fixed Carbon and Ash, focusing instead on the total volatile content.
