ABSTRACT
Depending on advanced technological developments in energy production the low quality coals needed the most economical technologies and even in order to make it possible to produce coal-derived products. Compliance with environmental norms of coal grinding or washing of various type of coals, feasible combustion systems and energy production facilities are needed in today’s modern technology, also enable the production of liquid and gaseous coal fuels. However, raw materials and chemical nature of them requires a variety of adaptation methods. For this purpose, universities and industry needing to work together to provide the basic information required in pilot scale. This study examined the high sulfur and ash types of Kütahya Gediz lignite, Sirnak asphaltite and coal shale. The representative samples were taken from local areas of the lignite. Fundamentally, the conditions regarding better desulfurization way, easy grinding lignite and washing, high calorific value lignite yield, 24% high Hardgrove Grinding Index were determined at the chemical grinding of high fuel producing yield. For this purpose, chemical ground further washing for Kütayha Gediz lignite, Sirnak asphaltite and coal shale were discussed.
