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.

To ensure burner safety, these valves maintain body temperature under 200°C with PTFE seals and 316 stainless steel bodies. Also, gas flow is modulated smoothly for better combustion with the proportional control valves (4-20mA input), which improve combustion efficiency by 12% in premix burners. In a German brewery’s kiln burner, our valves fast actuation improved controlled air-fuel ratio combustion resulting in quicker NOx emission reduction of 22%. This is achieved without compromising standby performance, as the valves’ magnetic latching technology improves standby power consumption by 85%.

Frequently Asked Questions

Do you think that Stiefel's Boiler Burners can work with smaller commercial boilers?

Stifel's burners will work perfectly for you. As an example, commercial boiler burners (20–500 kW) manufactured by us are intended for small areas and have a maximum radiation level of noise ≤70 dB. Furthermore, they can be installed quickly (plug-and-play electrical connectors). A French bakery was able to install our 50kW gas burner into their current boiler room. This resulted in thermal efficiency of 92%. Baking times also improved by 15%. Furthermore, the bakery was able to comply with noise regulations. With the HMIs' touchscreens, the operations can be performed through simple command inputs. Hence, less training is required with regard to adjusting temperature controls.
