Efficiency & Compliance
Squeeze more energy out of every fuel molecule while meeting the strictest global emission standards.
O₂ Trim Control
An O₂ trim system uses a flue-gas oxygen sensor (usually a zirconia probe) to continuously measure excess oxygen in the exhaust. The control system then fine-tunes the combustion air flow to hit the target excess air level (commonly 3% O₂ for natural gas).
Heat Recovery Integration
While not a feature of the burner itself, we integrate heat recovery devices like economizers and air preheaters. Preheating the combustion air effectively boosts the burner’s efficiency since warmer air promotes better fuel evaporation.
Regenerative burners alternate firing and heat recovery cycles to reuse exhaust heat, potentially cutting fuel use dramatically (sometimes by ~50% in furnace applications).
Premix & Surface Combustion
In premix designs, fuel and combustion air are thoroughly mixed before reaching the burner throat. Some ultra-low-NOx burners use a metal fiber or ceramic surface where the flame combusts in many small micro-flames.
This ensures very complete combustion at lower temperatures, boosting efficiency and lowering NOx/CO simultaneously.
Low NOx & Emissions
Industrial burner manufacturers use strategies like Flame Staging and Flue Gas Recirculation (FGR) to minimize pollutants.
Strategies
- Flame Staging: Splits fuel/air into primary and secondary zones to keep the flame cooler.
- FGR: Recirculates exhaust gas to dilute the flame and lower temperature.
- Compliance: Our burners meet stringent standards like EN 676 (Class 3) and local AQMD rules (< 30ppm or < 9ppm NOx).
