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

19 July 2017

Fulton’s all-new heat transfer solution, the VSRT Series, is claimed by the company to be the most radical change to vertical steam boiler design since they pioneered the vertical tubeless boiler in 1949!  

By adopting a systems engineering approach to design and using its own ‘PURE’ technology, Fulton’s VSRT Series challenges the traditional heat transfer and mechanical design principles of vertical steam boilers. The VSRT also boasts industry-leading performance with an 84.5% Gross (93.5% Net) thermal efficiency from a fully-water-backed design with no refractory.

Commenting for Fulton, managing director Carl Knight says: “With 30+ worldwide patents pending, the boiler’s spiral-rib tubeless design is a world first and creates a compact boiler with the industry’s smallest footprint. In fact, compared to equivalent 30hp Fulton J Series models, the VSRT is an impressive 40% smaller.”

Using in-house modelling with CFD and finite element analysis, the VSRT’s ‘PURE Optimised’ architecture makes it durable and reliable, with up to 6:1 turndown through its fully-modulating burner.

The VSRT is CE marked and complies with anticipated EU regulations, with its combustion technology being reconfigured and the mesh burner and furnace designed as a single component, resulting in NOx emissions of less than 40mg/kWh.
