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 .
