How Do Low NOx Burners & Boilers Work?

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 reduces the amount of available oxygen in the hottest part of the flame, which improves the efficiency of the burner. In conventional low NOx burners, combustion, reduction, and burnout are achieved in three different stages.

  • STAGE 1:  Combustion occurs in an oxygen deficient, fuel rich environment. This is typically where the NOx is formed.
  • STAGE 2: A reducing atmosphere follows where the hydrocarbons are created. These hydrocarbons interact with the already formed NOx.
  • STAGE 3: In the final stage, additional NOx may be formed from the completion of the internal air staging. However, this additional NOx can be further minimized by conducting the combustion in a lean air environment.

Low-NOx Technology

Boiler and burner technology uses heat to produce hot water and/or steam. In the combustion process, nitrous oxide (NOx) and nitrogen dioxide are produced as byproducts. These pollutants can initiate harmful reactions, which result in the production of acid rain and ozone. In general NOx comes from three main sources:

  • Thermal NOx is the result of high-temperature combustion. Thermal NOx is the largest contributor to overall NOx emissions
  • Prompt NOx is when nitrogen bounds to the fuel
  • Fuel-bound NOx, which is typically not a concern with natural gas
