Byworth has improved on its 20-year-old Yorkshireman boiler, introducing the re-vamped Yorkshireman 2.
As part of a four year R&D program, run in conjunction with the Mechanical Engineering Department of Leeds University, Byworth is now offering the Yorkshireman2 with a typical increased efficiency of 2.5%.
The Yorkshireman 2 has an efficiency of around 92.3%. After lengthy testing of different types of tube and tube configurations, Byworth claims to have proved that by incorporating X-ID Tubes in place of the common plain boiler tubes, the heat transfer rate is improved by up to 85%.
This is achieved not only by an increase in surface area, but also by an enhanced turbulence around the inner tube wall.
X-ID tubes have been tested at Byworth over two years in both simulated and actual steam boiler application, and have been proved to increase the efficiency of the boiler by up to 2.5 percent.
The company estimates that as compared to a typical gas bill for a 10 tonne boiler operating at 80 percent efficiency on a medium load of say £30,000 per month, a standard Yorkshireman at 90% efficiency would reduce the monthly fuel bills to around £26,000.
