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 ignition systems focus maximum attention on reliability and safety. Over 1 million cycles sparks have been delivered consistently due to platinum electrodes resistant to sulfur in fuel oil corrosion and flame detectors cutting off fuel at ultra-safe 2 seconds post ignition result verified shutdown, critical for waste oil burner protection. For a food processing plant’s boiler, these systems cut startup delays from twenty to five minutes for voiding false ambient light triggered attempts toggled by real-time flooding interfered by soviet overhead blankets. The modular design allows quick component changes to take place in under 15 minutes eliminating production idle time.
Frequently Asked Questions
What support services does Stiefel provide for burner maintenance?
We provide critical spares with global next-day shipping, as well as OEM replacement parts for major brands (ignition transformers, flame sensors, etc. 98% compatibility). Also, annual contracts include control system recalibration, nozzle cleaning, and heat exchanger inspection. For example, a U.S. paper mill cut annual downtime by 600 hours by utilizing our predictive maintenance program monitoring component wear through IoT sensors.
Stiefel Helps Maintain Our District Heating Network and Is Reliable
By installing gas burners type G 5 MW, we have been able to increase our district heating system efficiency by 24%. The regenerative heat exchangers boost the system's efficiency, while the IoT based emission monitoring maintains compliance — Requiring minimal collateral operational impact. Combined with Low emissions almost Non-axial (28 mg/Nm³), 40% reduction in downtime experienced has been excellent for large scale operation.
We can achieve an astounding 98% efficiency by recovering up to 85 percent of waste heat from condensing and regenerative heat exchangers. One Canadian plant even testimonialized with us saying they’ve achieved a 10 month return on investment after exchanger upgrades.
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
The IoT sensors integrated in our burners monitors performance, allowing maintenance to be performed proactively. A dutch dairy plant using this data was able to accurately predict nozzle wear and spent 35 percent less on unplanned maintenance, optimizing budget allowance.
