steam Yorkshireman Steam Boilers


Our Yorkshireman steam boilers are advanced three-pass wetback shell steam boilers which are ideal for heavy continuous workloads.

Well proven over many years across the world, the Yorkshireman steam boiler is preferred by engineers across many industries including Food & Drink, Pharmaceutical, Laundry, Paper and Packaging, Petrochem, Animal Feeds and Healthcare.

• 100mg NOX on gas
• 200mg NOon light oil
in line with the expected requirements of the UK implementation of the Medium Combustion Plant Directive legislation


Aware that running costs are of paramount importance to steam users, in 2007 Byworth embarked on a 2 year Research and Development Project in conjunction with Leeds University.  The brief was, by rigorous testing, to ascertain and prove the optimum configuration of shell, furnace, and tubes for maximum boiler efficiency and low emissions.

The project almost came to an early close when on testing the existing Byworth Yorkshireman range of boilers, it was found that efficiency results for this range were actually higher than previously claimed and better than similar boilers available! The generously sized shell and furnace design proved to generate best quality dry steam with low emissions and so has been retained in the Yorkshireman2.

The most exciting feature of the Yorkshireman2 boiler range is the revolutionary X-ID boiler tubes. With special helical internal ribs, this tube gives a significant 80% increased heat transfer over normal tube.  This increase in heat transfer gives the Yorkshireman2 an efficiency figure of around 95% (NCV). Moreover, when compared to the running costs of an older existing boiler plant, fuel savings could be as much as 20%.

This large boiler range incorporates many energy saving features including the unique X-ID boiler tube, making the Yorkshireman2 probably the most energy efficient steam boiler available today.
