Pollution Control in Boilers | Just Venting

Oct 30, 2019 · The selection of fuel to burn in the boiler is the first opportunity to reduce flue gas contaminants. For example, natural gas burns cleaner than fuel oil, medical waste, or biomass and produces the least amount of pollutants in its flue gas. Natural gas is considered a low-nitrogen fuel and yields very little NOx as a by-product of combustion.

The whats, hows and whys of NOx emissions in commercial boilers

In a commercial boiler, fuel such as natural gas is ignited which is used to heat water to be distributed in the heating system. In theory, this involves the burning of only methane (CH 4 – main component of natural gas) and oxygen (O 2 – injected air) which produce carbon dioxide (CO 2) and water (H 2 O).
