The effect of main parameters on the decrease of sulfur and volatiles content, as well as on the increase of ash content has been investigated. The kinetic regularities providing the process in the kinetic area have been determined for different ranks of coal. The interference of black coal cleaning and desulfurization has been studied. The coal may be cleaned followed by obtaining flotoconcentrate with ash content of 10 wt%. The adequate mathematical model of low-methamorphized coal desulfurization has been developed. The principal flow sheet has been proposed to obtain the raw material for pulverized-coal fuel.5481 Product Description popup.authors Астахова Олена Тарасівна Братичак Михайло Миколайович Гунька Володимир Мирославович Пиш'єв Сергій Вікторович Присяжний Юрій Володимирович Фридер Ірина Вікторівна popup.nrat_date 2020-04-02 Close
