The quantity of volatiles evolved from a coal at a fast rate of heating has been shown to be a function of the temperature and atomic hydrogen-carbon ratio of the coal, thus- Vt = Pt (H/C – 0.72+0.0054 Pt) Where Vt is the quantity of volatiles, as percentage of unit coal, released by the coal having atomic hydrogen-carbon ratio H/C, at a temperature tºC and Pt is a function of temperature, having the same value for all coals subjected to the chosen temperature tºC. The variation of the value of P t can be found out from a P-t curve, represented by the equation. Pt=80.8 [1 – e-4.205×10-6x (t + 470) (t – 160] The relations explain the continuity of the devolatalisation process of a coal throughout any range of temperature, and show that the amount of volatiles which is evolved from the coal is mostly dependent on its H/C value.
