Combustion characteristics of Shiwei-Ovoo coal deposits in Mongolia for energy consumption

Pricing pressure on energy consumers of the Far Eastern Federal District is significantly higher than the national average one and it is determined to a great extent by transport cost of solid fuel import. That's why consideration of engineering issues of substitution of the region's energy supply sources with the nearest coal fields is important. For making a decision of using coal as energy fuel required comprehensive information about it: complex of its properties, such as thermal characteristics. For this purpose the authors have investigated Shiwei-Ovoo coal consignments using standardized Russian methods. The comparison of the results with quality indicators of coals widely used in the Russian thermal power confirms Shiwei-Ovoo coal as generally favorable for energy use. Thermal properties of Shiwei-Ovoo coal were estimated. It is classified as lignite with high yield of volatiles, medium sulfur and low ash content.
