摘要：In this paper the numerical model of combustion chamber of BP 1150 boilers of Opole Power Palnt with additional set of nozzles of protection air system was created. The calculation was done by commercial CFD code Fluent. Three case of air distribution to OFA and SOFA nozzles was modelled. The quota of air was increased to OFA and SOFA nozzles by taking secondary air from burners to decrease NOx emission. The distrubution of primary and secondary air was done so as to the quota of air from protection air system was at stable level equal 10% of secondary air. Numerical simulation of furnace of BP 1150 boilers confirmed that stagered air decreasing NOx emission and showed NOx concentration on varoius level of combustion chumber.
