With nitrogen being very common in the mix, both nitric oxide (NO) and nitrogen dioxide (NO 2) are just two of them. What affects the production of NO x emissions in commercial gas boilers? There are different types of NO x formation in combustion ( thermal, prompt, and fuel ) but for condensing gas boilers, thermal NOx is the most important one.
Heat Recovery contrast, a typical feedwater economizer might take some 100°F (55°C) of sensible heat out of the boiler exhaust, for an impact of roughly 3 percent. Condensing Heat Recovery Technology Condensing heat recovery can be applied in two ways: direct-contact and indirect-con-tact systems. Essentially, condensing heat

However, the oxygen content in air is only around 20%, with nitrogen representing 78% and other gases the remaining 2%. Whilst nitrogen plays no part in the combustion process, it should ideally pass through the boiler without reaction. However at temperatures over 1100°C, nitrogen and oxygen combine to form NO.
Condensing Boilers Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by using waste heat in flue gases to pre-heat cold water entering the boiler. Water vapor produced during combustion is condensed into liquid form, which leaves the system via a drain.
In the graph below you can see the dilution of the CO2 created by the excess air. Air is 20.9% O2, 78% Nitrogen and about 1% other gases. Because the air is only 1 5th oxygen the boiler will have to add 4 times the amount of other unrequired gases (mainly nitrogen) to the combustion, to obtain a relatively small amount of excess O2.
