The main sources of this fuel in the Russian Federation considered cuts and Kuzbass mines. They differ volatile substances from 8 to *8% of the vitrinite reflection index 1.3 - 2.*9. Coals this brand do not have the ability to sintering. coal and coke ash composition close. The ash prevail acid oxides. But because of the relatively low amount of carbon in the fuel mixture that does not affect the composition of the slag and does not require additional loading limestone. The ash melted at a temperature of to ° ****0S ****0S °. The heat of combustion of dry ash free weight is about *6,**0 kJ / kg, and mainly depends on the chemical composition of the coal, in turn, determines the degree of metamorphism. Typically, heat released by combustion of hydrocarbons contained in the lean angle, as well as hydrogen, so no ash weight may be higher than that of coke. When comparing the properties of bituminous coals, and coke is clear that the strength of the lump coal coke strength below and above. Coals have lower porosity, but the reactivity similar to coke. Skinny coal contains in its composition over the volatile components, less phosphorus and sulfur, and about the same amount of ash. Coal, whose sale is conducted today wide rate is characterized by a greater degree of thermal conductivity and lower the ignition temperature.
