Hurst Boiler Receives Patent for Internal Boiler Efficiency Device
Hurst Boiler has received patent approval for its new counter-flow device designed to improve boiler efficiency.
Integrated inside of the pressure vessel, Hursts optional counter-flow device is factory-built into the companys Thermal Master Counter-Flow Boiler Series and can be added to any of Hursts packaged Scotch Marine and Euro Series boilers, depending on desired efficiency requirements.
Hursts new counter-flow device improves boiler efficiency without increasing the heat transfer surface area and flue gas pressure drop through the boiler. The devices technology and engineering work as an economizer and aids to absorb more heat from exhaust gases by utilizing feedwater potential in a unique water-to-flue gas counter-flow design.
Performing the same function as a traditional external economizer typically used with conventional steam generation systems, Hursts patented internal counter-flow device captures the lost or waste heat from the hot flue and stack gasses of the boiler. Relative to other boilers having traditional designs, tests determined that the device improves boiler efficiency by as much as 3%, depending on working conditions.
