Change to boiler design

01 February 2017

Fulton’s new heat transfer solution, the SRT Series, is said by the company to be the most radical change to vertical steam boiler design since it pioneered the vertical tubeless boiler in 1949.


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

Carl Knight, MD, 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 SRT is an impressive 40% smaller.”

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

The SRT 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.
