Preparation of granules made of fine-grained coal fractions for gasification process
The paper presents the results of tests for the production of fuel granules from fine-grained coal fractions. The raw material used for the research was selected fine coal fractions - coal sludge and coal flotation concentrate, obtained from the process of coal enrichment in hard coal mines. The aim...
