  • Gas Technology Advisor

    One method to reduce NOx levels from boilers firing distillate oils is through the use of low nitrogen fuel oil. Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound nitrogen). When low NOx oil is fired in firetube boilers utilizing flue gas recirculation, NOx reductions of 60%-70% (over NOx emissions from standard No. 2 oils) have been …Learn More

  • How a Low-NOx Burner or Boiler Can Reduce Emissions

    Today's ultra low NOx boilers use advanced technology and methods to reduce NOx emissions. Low NOx burners are designed to control air and fuel mixing at each burner, which creates more branched and larger flames. By reducing the peak flame temperature, significantly less NOx is formed in the process. The improved flame structure simultaneously Learn More
