      Boiler Operations That Affect Efficiency (Part 2)

      Increased turbulence increases the air-fuel mixing. It also increases the combustion intensity, provides faster heat release, reduces unburned carbon (UBC) in the ash, permits operation with less excess air, and increases boiler efficiency. However, increased slagging, increased NOx emissions and higher fan power consumption can also result.

      The whats, hows and whys of NOx emissions in commercial

      In operational terms, there is already a lot that a user of commercial boilers can do to reduce NO x and carbon emissions. As outlined above, if a boiler is modulated down (lower fire), this improves efficiency and also decreases NO x emissions. Effective use of built-in boiler controls and measures such as weather compensation can reduce emissions.

      Plant Engineering | GAS TECHNOLOGY: Boiler NOx Emissions

      In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called “Ultra-Low NOx” (ULN) requirements, typically less than 10-12 ppm. It is widely believed that the ULN requirements will be broadened to more areas.

      The boiler produces steam and hot water for industrial process applications. Many boilers use an economizer to preheat the process water before it is fed to the boiler using waste heat from the exhaust gas. This combustion operation produces CO 2 emissions and is the focus of the emission reduction techniques presented in the remainder of
