FULTON’ S PURE TECHNOLOGY APPROACH ACHIEVES WORLD-FIRST VERTICAL STEAM BOILER DESIGN WITH HIGHEST EFFICIENCIES AND ULTRA-LOW NOX EMISSIONS
The gas-fired VSRT steam boiler emerges from Fulton’ s new‘ PURE Technology’ approach, an initiative that’ s delivered a world-first design that is durable, longlasting and boasts the highest efficiencies and ultra-low NOx emissions.
By adopting a systems-engineering approach and implementing PURE Technology – the result of a clean-slate design approach that combines new people with new skills bringing a new approach to the design and optimisation of heat transfer solutions – Fulton’ s VSRT radically challenges the heat transfer and mechanical design principles of traditional steam boilers. It’ s also claimed to be the most radical change to vertical steam boiler design since Fulton pioneered the vertical tubeless boiler in 1949. Commenting, Fulton’ s Leigh Bryan says:“ To meet stringent industry and environmental standards, PURE Technology looks to enhance heat transfer, provide classleading efficiencies, improve steam quality and reduce NOx emissions. Rather than improve existing products to achieve this, we are engineering new solutions that are fit-for-purpose and application.”
With 15 + patents pending in three continents, the VSRT attains industry-leading heat transfer rates thanks to a unique spiral-rib heat exchanger to achieve low stack temperatures by passing flue gases through a fully-water-immersed, spiralwound heat exchanger. This design extends the heat transfer path and dual-direction heat flow, with the spiral annulus designed and optimised to create high heat transfer rates. This improves efficiency and creates a longer-lasting boiler that Fulton believes will beat the competition in every category of durability thanks to virtually zero thermal stress, a thick-walled construction and its vertical tubeless design architecture.
A fully-water-backed pressure vessel is wrapped in high-density insulation to achieve minimal thermal losses and low outer surface temperatures; and the tubeless design has created a compact boiler with minimal footprint.
No refractory also means significantly lower weight to ease installation.
The VSRT’ s combustion technology achieves ultra-low NOx emissions of < 20ppm and features a fully-matched modulating burner and furnace purposely-designed as a single component.
This achieves > 10:1 turndown capabilities and industry-leading performance of > 82.5 % gross thermal efficiency and 99.75 % steam quality at 8 bar.
When correctly sized for applications, the exceptionally high turndown will result in savings above-and-beyond those gained from stated efficiencies.
With a tubeless design, no internal refractory, industrial control platform and easy access to the pressure vessel, the VSRT is easy to maintain and operate.
Maintenance is further improved thanks to a revolutionary air filter where, for contaminated combustion air environments that can reduce boiler uptime, a cyclonic air filter separates debris and damaging particles and eliminates the need for replacement filters.
The VSRT is currently available with outputs from 160-960 kg / h, complies with MCPD regulations and the City of London Air Quality Strategy; is constructed to BS EN 12953; and CE marked to PED. It comes with a five-year guarantee on the pressure vessel and burner.
