Fulton launches the most radical change to boiler design in nearly 70 years

By adopting a systems engineering approach to design and using its own ‘PURE Technology’, Fulton’s VSRT Series challenges the heat transfer and mechanical design principles of traditional vertical steam boilers.

With over 15 worldwide patents pending, the new vertical boiler’s spiral-rib tubeless design is a world first that has enabled Fulton to create a compact boiler with the industry’s smallest footprint. In fact, compared to the equivalent 30hp model from the company’s renowned J Series, the VSRT Series is an impressive 40% smaller.

Using a combination of in-house modelling with computational fluid dynamics and finite element analysis, the ‘PURE Optimised’ design of the VSRT Series makes the new boiler durable and reliable in operation; and with up to 10:1 turndown capabilities and featuring a fully-modulating burner, the SRT also boasts industry-leading performance with an >82.5% gross thermal efficiency and 99.75% steam quality from a fully-water-backed design with no refractory. The VSRT’s combustion technology is configured with the mesh burner and furnace designed as a single component, resulting in typical NOx emissions of <20ppm.

The VSRT is currently available with outputs from 160-960 kg/h, complies with the City of London Air Quality Strategy and anticipated MCPD regulations, is constructed to BS EN 12953 and CE marked to PED. Its pressure vessel and burner are backed by a five-year guarantee as standard.
