Low nitrogen combustion of gas boilers

Low NOx Boilers | Low Emission Boilers & Equipment

Thermal NOx is a byproduct of the combustion process that is formed by industrial boilers and process heaters when burning natural gas (and other fuel gases with no bound nitrogen), where high flame temperatures cause nitrogen molecules from the combustion air to combine with oxygen to form nitric oxide.

Ultra-low nitrogen oxides (NOx) emissions

The combustion in gas turbines has always been very lean, and will remain very lean at Ø = 0.6 for at least the next decade or more of gas turbine developments. This is why lean well-mixed combustion is the solution to low NO x in gas turbines. Gas turbine combustion also occurs in near adiabatic conditions, as the aim is not to extract heat

Low-NOx Emission Burners for Industrial Boilers

2019-3-20 · FGR is the process by which exhaust gas is introduced into the combustion-air stream prior to a burner. Flue gas also is relatively cool (300°F to 550°F, depending on the design of the boiler and whether there is a feedwater economizer) with respect to flame temperature, and flue gas has little oxygen from the combustion process.

Emission characteristics of NOx, CO, NH3 and VOCs

For the gas-fired industrial boilers without low-NOx combustion techniques, EF NOx and EF CO of ACBs were 3.08 and 0.54 g/m 3, which were about 2.2 and 1.2 times higher than the EFs of CCBs, respectively. It indicated that combustion mode was the significant factor affecting the formation of gaseous pollutants.

⇔ Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).
