Thermal Coal – IspatGuru

Thermal Coal – IspatGuru

The proximate analysis of thermal coal determines the percentage of fixed C, VM, moisture and ash in it. The various parameters of proximate coal analysis in case of thermal coal have considerable significance. Fixed C acts as a main heat generator during burning and it gives a rough estimate of heating value of coal.
