Effect of mechanical dispersion of lignite on its thermal decomposition.

Yusupov, T. S.; Shumskaya, L. G.; Burdukov, A. P.

It is studied how the high-rate mechanical grinding affects thermal decomposition of lignite extracted from the Kansk-Achinsk Coal Basin. It has been shown that dispersion of lignite in the high energy intensive vibration-centrifugal and planetary mills causes formation of structures exhibiting lower thermal stability. That results in the shift of primary decomposition phenomena into the low-temperature region and, thus, in the higher reactivity of coals.
