FIELD: methods of burning coal in burner by means of blast air. SUBSTANCE: prior to admitting coal dust to pulverized-coal burner, it is separated from mixture of coal dust and carrier gas mixed wit preheated air and is transferred to mixture of coal dust and carrier gas at elevated temperature and lesser fraction of content of coal dust in order to enhance burning of coal by means of blast air. Then coal dust is again separated, mixed with preheated air and transferred to mixture of coal dust and carrier gas at elevated temperature and increased fraction of content of coal dust. EFFECT: enhanced efficiency. 6 cl, 4 dwg
