GAS TECHNOLOGY: Boiler NOx Emissions

For many operators of industrial boilers, an important first step was to change from coal or oil boiler fuels to natural gas, which is cleaner burning in many respects. However, NOx continues to be a target. With natural gas, fuel based nitrogen is not the concern, but the use of air for combustion does provide the primary source for NOx.

Boiler

Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber.

Is a high efficiency, condensing gas boiler the best choice

In these applications, condensing boilers do not use indoor air for combustion and require a means to vent the boiler directly to the outside (not chimney venting). In homes where it may be impractical to vent a boiler directly to outside air without using a chimney, a conventional cast iron gas boiler may be a more viable option.
