Recommended Mill Outlet Temperature Based On Coal Fuel Ratio

  • Chapter 2 Selective Catalytic Reduction - US EPA

    In practice, commercial coal-, oil-, and natural gas–fired SCR systems are often designed to meet control targets of over 90 percent. However, the reduction may be less than 90 percent when SCR follows other NO x controls such as LNB or FGR that achieve relatively low emissions on their own. The outlet concentration from SCR on a utility .
