OSTI ID:20082361
Tavanl-Omerler lignite deposit with a reserve of 264 million tons forms an important section of Turkish lignites. This lignitic coal was subjected to washing, semi-coking and magnetic separation so that the total sulphur and ash contents were reduced from 4.08 % to 1.27 and 15.64 % to 8.5 % respectively. The calorific value of the solid fuel was raised from 5030 Kcal/kg to 6727 Kcal/kg and the volatiles can also be used after sulphur removal. This process appears to be feasible as a clean coal production from the point of energy efficiency. A short economic analysis is also presented.
