Abstract
The article presents the results of summary indicators of granulometric composition with data on the ash content of dry fuel in each class of size. During the work, it was found that the coal sludge of Kuzbass is mainly composed of high-ash fine-dispersed material. The presence of large particles has been established, in the composition of which there are non-combustible phases represented by some inorganic substance. Potentially promising ranges of size have been identified for obtaining additional fuel.
Keywords
Coal sludge, granulometric composition, ash content index, Kuzbass, utilization of coal waste filling fuel.
