What is an ultra-low nitrogen burner?

The two sessions in early March, clearly put forward "continue to improve environmental quality, improve the ecological protection compensation mechanism, in-depth pollution prevention and control actions. In the report requires the "14th Five-Year" period nitrogen oxides and volatile organic compounds emissions fell by more than 10% respectively. In order to target the suppression of large amounts of nitrogen oxide emissions, the need for environmental technology reform of the boiler, which plays an important role in ultra-low nitrogen burners.

Nitrogen oxides (NOx) are compounds composed of two elements, nitrogen and oxygen, the most important of which are NO and NO2. small amounts of NOx also exist in nature, but most of them come from transportation and energy production. The heat-using equipment with burners can be divided into three main categories of NOx according to the causes of formation during the combustion process.

1.thermal NOx: NOx is generated by the oxidation of nitrogen in the air at high temperatures during combustion.

2.Fast NOx: NOx is formed by the reaction of nitrogen in the air and hydrocarbon ion groups in the fuel during combustion

3.Fuel-based NOx: NOx is generated from the thermal decomposition of nitrogen oxides in fuel by oxidation during the combustion process.

Retrofitting combustion equipment belongs to the combustion process pollution prevention technology, is through the replacement of ultra-low nitrogen burner or the implementation of flue gas recirculation transformation and other measures to achieve low nitrogen emission requirements. As far as the current boiler retrofit market is concerned, the more common technology is flue gas recirculation (FGR); this technology may bring negative effects such as inadequate combustion of fuel and coking of the furnace chamber while reducing NOx emissions.

The EBICO ultra-low nitrogen burner focuses on the frontier of combustion technology, abandoning the traditional external flue gas circulation, and comprehensively adopting low nitrogen technologies such as vacuum internal mixing, super-mixing, multi-layered staggering, positive and negative oxygen combustion, to achieve ultra-low nitrogen emissions of less than 30 mg/m3 NOx, meeting the most stringent domestic and international air pollutant emission standards.
