THE INVESTIGATION OF THE EFFICIENCY OF THE NITROGEN OXIDES REDUCTION BY ADVANCED REBURNING METHOD APPLICATION WITH THE COAL DUST AS A REBURNING FUEL
Keywords:
coal combustion, CFD, nitrogen oxides
Abstract
The investigation of the influence of the low reactivity reburning fuel coal dust on the simultaneous processes of the nitrogen oxides reduction in accordance with the mechanisms Reburning and selective non-catalytic reduction was carried out. The study showed the possibility to reduce the nitrogen oxides emissions up to 80 % compared with single-stage coal combustion.
