In this paper a numerical model was created for the combustion chamber of BP 1150 boilers of Opole Power Plant with an additional set of protection air system nozzles. The calculation was using Ansys Fluent CFD. Three cases of air distribution to OFA and SOFA nozzles were modeled. The ratio of air was increased to OFA and SOFA nozzles by taking secondary air from burners to decrease NOx emission. The distribution of primary and secondary air was done so that the ratio of air from the protection air system was at a stable 10% of secondary air. A numerical simulation of the furnace of BP 1150 boilers confirmed that staggered air decreases NOx emission and showed the NOx concentrations at various levels of the combustion chamber.
