Low NOx Burners by Stiefel - Ultra Low Emission Combustion Solutions

Stiefel knows how to tame NOx. Their low-NOx burners use FGR, staged combustion, and smart premixing tricks. The result is flue gas that often weighs in at 30 mg/Nm3 of NOx or less. European CE certification covers everything from commercial boilers to heavy industrial furnaces and ceramic kilns. Even with that wide range, operators still see thermal efficiency numbers flirting with 98%.

Stiefel's Industrial Burners advantages

NOx emissions control reduction technology

The latest Stiefel burners come packed with smart tech that really cuts NOx fumes. With features like staged combustion and flue-gas recirculation, we hit numbers around 20 mg/Nm³, well under Californias strict CARB limits and the E.U.s EN 303-5. A winery in Northern California swapped in these FGR-equipped units and sliced its NOx output from 80 mg/Nm³ down to 18 mg/Nm³, matching the tight regional cap. That kind of drop isnt just good news; it keeps the facility on the right side of the law. Also, the burners can flip between gas, oil, and even biomass without breaking a sweat. Toss in a 20% hydrogen or biogas blend, and the unit keeps running smooth, giving operators one less headache when climate rules shift.

Low-NOx burners from Stiefel (Guangdong) Energy Environmental Protection Engineering Co., Ltd. aim to slash nitrogen-oxide emissions and still burn fuel pretty well. That balance helps plant operators stay on the right side of tough pollution rules. The engineering team folded in tricks like staged combustion and flue-gas recirculation; both methods cool the flame just enough to keep NOx from sky-high levels. A hardened alloy skeleton stands up to the daily grind of heat and pressure, so operators can count on years of trouble-free service. These burners slip into boilers, furnaces, or any heavy-duty heater you can name, making them a natural fit for factories that want green credibility without sacrificing steam or heat output.

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.

Advanced Energy Recovery

Advanced Energy Recovery

Condensing and regenerative heat-exchanger tech now snag as much as 85 percent of waste heat and recycle it back into the system. Overall efficiency can nudge right up to 98 percent. One Canadian plant upgraded its exchangers and pocketed the savings in just 10 months-a payback period most engineers still talk about over coffee.
Global Certification and Compliance

Global Certification and Compliance

CE, UL, ATEX, and CSA certification approves the widerange compliant standards our burners meet. For example, hydrogen capable versions of our burners further the EU’s Green Deal and US decarbonization objectives, guaranteeing forward looking solutions
Data Driven Predictive Maintenance

Data Driven Predictive Maintenance

Many modern burners now come with built-in IoT sensors that keep a constant eye on how well the unit is running. When something drifts out of line, a tech crew can step in before real trouble starts. One Dutch dairy plant made good use of that real-time info and soon learned exactly when its nozzles were wearing thin. The result was a remarkable 35 percent drop in unplanned repair bills, leaving extra cash in the budget for other projects.
