July 10, 2014: Hurst Boiler Announces Patent for Internal Boiler Efficiency Device
Represents a New Concept in the Design of Fire Tube Steam Boilers
COOLIDGE, Ga. — Hurst Boiler has announced patent approval for its new counter-flow device designed to improve boiler efficiency. Integrated inside of the pressure vessel, Hurst’s optional counter-flow device is factory-built into the company’s Thermal Master Counter-Flow Boiler Series and can be added to any of Hurst’s packaged Scotch Marine and Euro Series boilers, depending on desired efficiency requirements.
Representing a new concept in the design of fire tube steam boilers, Hurst said its new counter-flow device improves boiler efficiency without increasing the heat transfer surface area and flue gas pressure drop through the boiler. The technology works as an economizer and aids in absorbing more heat from exhaust gases by utilizing feedwater potential in a unique water-to-flue gas counter-flow design.
