Advantages of Stiefel's Boiler Parts

Customizable Solutions for Diverse Boiler Applications

Stiefel specializes in tailor made parts to fully service an operation’s diverse needs. For waste-to-energy plants, we offer flue gas processing valves for boilers, which increases the part life from 6 months to three years thanks to its Hastelloy sealing. Compact solenoid valves (1.5” NPT ports) for commercial kitchens can be retrofitted, thus cutting installation time by 30%. Seeing the need for global compatibility, we provide 24V DC/230V AC dual voltage control modules, like the one used by a Caribbean resort in their solar powered boiler system that had to seamlessly work with local grid controls.

To ensure burner efficiency, these valves support full proportional control with a 4–20mA input and smooth turndown ratios up to 10:1. In a Dutch greenhouse’s dual fuel burner, tighter staged combustion control enabled by our valves fast actuation improved NOx emissions by 25%. This design increases combustion efficiency by 15%, while the magnetic latching feature that supports position holding without power cuts standby energy use by 90%.

Frequently Asked Questions

In what ways does Stifel protect and enhance the lifespans of boiler parts with respect to high temperatures?

On our part, we apply Inconel, tungsten carbide, and ceramic coatings to these structures. At a powerplant in the U.K, we've had success with spiral fin heat exchangers. They not only possess ceramic coatings but also resist sulfuric acid corrosion found in high sulfur gas boilers. We've maintained 92 percentage thermal efficiency over a decade. Precession platinum rhodium tip ignition electrodes sustain over ten thousand cycles at a staggering 1,400 degrees centigrade. These outperform stainless steel electrode alternatives deemed ‘standard’ by thrice for industrial furnaces.

Easier Maintenance Saves Time and Money with Stiefel

Stiefel also helps us cut expenses with their readily available inventory. Construction managers have a lot on their plate; I focus on multiple commercial buildings and the value Stiefel’s components brings. Their solenoid valves and control panels are equally as good as OEM parts, but at half the price. For commercial contracts, bulk discounts have saved us over $10,000 annually. Restocking is easy with the online ordering system.
