Benefits of Stifel’s Burner Parts

Stiefel's components are specially designed to have great quality ensuring durability for an industrial purpose. The carbide tipped nozzles heightened resistance to abrasion in biomass burners by five times compared to standard stainless steel. This also decreased maintenance frequency by eighty percent in a Swedish pellet plant. Inconel combustion chambers in stiefel industrial burner kits outperform generic parts by three years enduring 1,600 degree celcius in a steel mills reheating furnace. Every part from solenoid valves to ignition electrodes are tested with 10,000 cycle load tests and helium leak checks to ensure compliance to ISO 9001 and operational reliability of 99.9%.

Custom Built Solutions fit for Other Boiler Systems

Our company supports customized burner designs for commercial, industrial, and waste-turned energy boilers with heating capacities between 20kW and 20 MW. The 100kW gas burner with full modulation (10: 1 turndown ratio) installed in a UK hospital’s steam system optimally controlled the temperature within ±2°C accuracy with a 22% reduction in energy wastage. Our control panels are fully IoT compatible, enabling connection with SCADA systems for real-time data and fuel consumption monitoring as well as emission control. We cover all bases when it comes to old and new boilers, ensuring dismantled systems or fresh builds are operable with oil, gas, biomass, waste, and even unusable fuels.

Actuators come self-equipped with self lubricating bearings and corrosion resistant coatings, remaining useful in extreme heavy duty conditions. Electric models with servo control offer accuracy in airflow control for premix burners, while explosion proof certified pneumatic actuators suit hazardous zones. In South Saudi Arabian refineries, these actuators outperformed standard models by two times in service life, enduring a whopping 180 degrees celsius and high vibrations. Quick replacement of drive gears is made easy with modular design, allowing for replacement without removing the valve.

Frequently Asked Questions

What kind of support does Stiefel offer for maintenance of boiler burners?

Our offers include complete maintenance services, which comprise OEM replacement parts (solenoid valves and ignition transformers, for instance) with 98% cross-compatibility to major brands. Speed is a priority for our global network, providing same-day shipments for critical components. Remote diagnostics is also available via IoT connectivity, handled by our technical teams. Our tungsten carbide nozzles resulted in an 80% reduction in clogging incidents for a U.S. paper mill, and annual maintenance contracts offer advanced evaluation to prevent performance drop-off.

Breakthrough Development on Low-NOx Standards Preset

Breakthrough Development on Low-NOx Standards Preset

We are proud to highlight that the use of advanced FGR and premixing technologies on our gas burners has achieved an industry best NOx emissions figure of 20 mg/Nm³. These are proven commercially and set to the greatest stringent environmental regulations, receiving guaranteed NOx compliant emission status for years to come. A Californian Food Processing Plant was able to save $40,000 in penalties over three years simply by switching to our low-NOx burners.
Advanced Burn Control

Advanced Burn Control

Fuel emission and maintenance functionalities can be monitored and controlled in real time via PLC control panels, which comes as standard with Stiefel’s gas burners. This data is invaluable: A German Automotive Factory used it to claim a 19% reduction in energy waste, alongside predictive maintenance of failing nozzles allowing them to reduce downtime by 35%.
