Hurst Boiler receives patent for internal boiler efficiency device

Hurst Boiler announced the patent approval for its new counter-flow device designed to improve boiler efficiency, which will be presented at IWF 2014.

Integrated inside of the pressure vessel, Hurst’s optional counterflow device is factory-built into the company’s Thermal Master Counter-Flow Boiler Series and can be added to anyof Hurst’s packaged Scotch Marine and Euro Series boilers, depending on desired efficiency requirements.

Representing a new concept in the design of conventional fire tube steam boilers, Hurst’s counter-flow device improves boiler efficiency without increasing the heat transfer surface area and flue gas pressure drop through the boiler, according to the company.

Performing the same function as a traditional external economizer typically used with conventional steam generation systems, the device captures the lost or waste heat from the hot flue and stack gasses of the boiler.
