The paper presents the results of numerical simulations in Computational Fluid Dynamics Code Code_SaturneŽ of existing protection air system in front wall fired boiler KS type OP6S0 in Rybnik Power Plant (ERSA). Simulations without existing protection air system (WPAS), with existing protection air system (EPAS), with simple modification of existing protection air system (MEPAS) by changing the direction of protection air nozzles, and with more expensive modification by adding new air nozzles (NEPAS) were done. The influence of the swirl in OFA ports on the flue gas composition near the walls was determined. The paper presents also the dependence between the primary, secondary and tertiary air swirls directions in the bumers and the flame symmetry in the fumace.
