The OVERFIRE System ensures the reduction of CO, NOx and unburned particles emissions. Incandescent particles in their ascending path receive 21% oxygen and incinerate, while larger particles are precipitated towards the combustion zone by the effect of the air curtain. This system is optimized for each boiler using three-dimensional development software.
