  • Selective Non-Catalytic Reduction

    Selective Non-Catalytic Reduction (SNCR) offers a lower-cost method of reducing nitrogen oxides than Selective Catalytic Reduction. For smaller or older power plants, SNCR is the NOx control installation of choice. It can also sometimes be an interim technology before an SCR can be installed. Although the removal efficiency is between 25 and 35%, ...

  • Overfire Air Systems

    Overfire Air (OFA) works by diverting a portion of the total combustion air away from the primary combustion zone. Overfire air lowers the air-to-fuel ratio at the burners, lowering the oxygen in the primary flame zone, which reduces NOx conversion of fuel-nitrogen in volatiles and reduces thermal NOx formed in the primary flame zone.
