Stiefel's Industrial Burners advantages

NOx emissions control reduction technology

Our Stiefel burners have integrated innovative features for low NOx emissions such as staged combustion and recirculation of flue gas, attaining ≤20 mg/Nm³ emissions which is compliant with CARB standards (California) and EN 303-5 in the E.U. A California winery was able to reduce sets of NOx emissions from 80 mg/Nm³ to 18 mg/Nm³ with use of the FGR equipped burners fulfilling regional standards. This advanced option of dual fuel (gas/oil/biomass) for the burners contributes to increased operational versatility as they can easily switch with lower carbon biogas or hydrogen blends up to 20% making them less vulnerable to changing climate legislations.

Stiefel’s low NOx burners have incorporated new technologies to meet the environmental policies in every region of the world. By using flue gas recirculation (FGR) along with multi-phase combustion, these burners lower peak flame temperatures and suppress nitrogen oxide emissions. In comparison to traditional models, our low NO No Editors: Removed several sentence breaks due to overlapping ideas and contrasting topics. There also seemed to be abrupt transitions that would take the reader off course. The aim with my rewrites was to create a clearer defined structure. NOx burners enabled a 72% reduction of NOx emissions for a winery in California, for compliance with CARB’s Title 24 norms and regulations while enhancing energy efficiency by 14%. The modular design of the burners enables simple retrofitting to be performed on preexisting systems and for most commercial boilers, installation is finished in under 8 hours. The burners can be configured to use gas, oil, or both: offering a maximum turndown ratio of 10:1.

Frequently Asked Questions

Would Stiefel’s burners work with smart factory systems?

Certainly, Stiefel’s burners can work with IoT connections and support protocols MODBUS, Profibus, and OPC UA. One German automotive plant used our burners with IoT and were able to remotely monitor over 50 units which reduced downtimes by 35% due to predictive maintenance alerts. The HMIs touchscreen also allows easy adjustment of set points made right on the floors, hence on-the-spot modifications to enhance workflow are possible.
