Oxides of Nitrogen (NOx)

REI advises clients on a wide variety of NOx control technologies. We use our CFD and other modeling tools to predict emissions in utility and industrial boilers for integrated NOx control:

  • Low NOx burner
  • Staging, Overfire Air (OFA), ROFA
  • Burner Optimization and Balancing
  • Flue Gas Recirculation (FGR)
  • Gas and Coal Reburning
  • Fuel Lean Gas Reburning (FLGR)
  • Selective non-catalytic reduction (SNCR)
  • Rich-Reagent Injection (RRI)
  • Fuel Blending and Switching
  • Biomass and Syngas Co-firing

When we evaluate NOx control strategies, we do more than prediction NOx emissions. REI has the tools and expertise to look at aspects of NOx control that affect operation and performance of combustion systems, including:

  • Unburned Carbon-in-ash (LOI)
  • Waterwall Wastage and Corrosion
  • Deactivation of SCR Catalyst
  • CO Oxidation
  • Fouling and Slagging
  • Fuel Efficiency
  • Furnace Heat Transfer
