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%.

Bespoke Solutions for the Comprehensive Range of Burner Services

Stiefel excels in the waste-to-energy sector, having developed proprietary Hastelloy-sealed valves for a German incinerator that resist acidic flue gas corrosion, increasing part life from 6 months to 3 years. We designed smaller solenoid valves with 1.5 NPT ports for commercial kitchens, saving 30% installation time with quick-connect terminals during retrofits for a French bakery chain. Many of our clients require compatibility with both 24V DC and 230V AC power, evidenced by dual fuel burners at a Caribbean resort that switch effortlessly from gas to diesel.

These burners lead the pack using pre-mixing chambers to guarantee consistent gas-air blending which eliminates hot spots and bad NOx creation. Equiping the boilers of a restaurant chain in California with our premix burners allowed them to satisfy CARB's stringent NOx regulations (<30mg/Nm³) achieving a 15% increase in energy efficiency. The burners tight (=0.8m^3) mechanical room footprint also allows for minimal blower energy consumption due to the low pressure drop (<0.5 bar).

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 have achieved industry-leading NOx emissions of 20 mg/Nm³ through the deployment of advanced FGR and premixing technologies on our gas burners. This achievement surpasses the most stringent environmental regulations and delivers guarantee on NOx compliance in emissions for years to come. A Californian Food Processing Plant saved $40,000 in fines over three years 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%.
