World-first’ vertical spiral-rib tubeless steam boiler launched

An ‘all-new’ gas-fired, vertical spiral-rib tubeless steam boiler from Fulton, the VSRT, is the first range to emerge from its new ‘PURE Technology’ approach, resulting in ‘a world-first design that is durable, long-lasting, and boasts the highest efficiencies and ultra-low NOx emissions as standard’.

Fulton says the VSRT ‘radically challenges the heat transfer and mechanical design principles of traditional steam boilers’. It is claimed to represent ‘the most radical change to vertical steam boiler design’ since Fulton ‘pioneered’ the vertical tubeless boiler in 1949.

The company said: “With over 15 patents pending in three continents, the VSRT’s spiral-rib heat exchanger is a world first. It attains industry-leading heat transfer rates thanks to its unique spiral design, which achieves low stack temperatures by passing the flue gases through a spiralwound heat exchanger fully immersed in water. The heat exchanger design not only ensures improved boiler efficiency, but, with virtually zero thermal stress, a thick walled construction, and vertical tubeless design architecture, also makes the VSRT one of the most durable steam boilers available.”
