Product Description

High-Efficiency Low NOx Gas Burner for Steam Boilers

Product Description

The high-efficiency energy-saving and ultra clean technology burner with ultra-low nitrogen oxide emissions is based on the technical principle of optimizing the combustion technology and combustion system of industrial furnaces and heating furnaces. Through the combination of staged combustion, multiple combustion, oxide supply, flame plasticity of braze bricks, flue gas reflux, ultra adiabatic combustion and other technologies, the flame center temperature or local high temperature is reduced to achieve ultra-low NOx emissions.

3. Ultra low NOx burner characteristics

1) Disperse the fuel in space for supply, effectively reducing the temperature at the center of the flame.;
2) Stable flame, mixed with secondary gas for further combustion, promoting complete combustion;
3) The flue gas will undergo heat exchange, transferring heat to the gas and combustion air.--an increase in inlet temperature will enhance combustion;
4) The effect of the shape of the brazier brick on fluid flow can intervene in the shape of the spreading flame;
5) By switching the fuel supply on the ring according to specific rules, a swirling flame can be achieved, which can avoid furnace flame erosion.

4. Smoke assurance indicators

Oxygen content in flue gas (O2): 3% (mol dry basis)
NOx concentration: 50mg/Nm ³;
CO concentration: 40mg/Nm ³;
Particulate matter: ≤ 20mg/Nm ³;
Unburned hydrocarbons: ≤ 20mg/Nm ³
