Recent development in lignite investigation hejaszifhuA Technical Assessment of Coal Utilization and Research Trends

Recent development in lignite investigation It is worth mentioning some interesting utilization advantages of lignite over higher rank coalBecause of its high reactivity which is due in part to high oxygen content lignite does not have to be ground as finally as higher rank coal to ensure complete combustion in pulverised coal systems Advantages for gasification and liquefaction are 220 to 280xJ and coal utilization occurs at a rate of 36TW2 4 Even if the utilization Even if the utilization rate doubles the coal resource will last several thousands of years
