Counter Flow Series

Thermal Master can be built in any Hurst Steam Boiler and boost efficiency by 3-5>#/p###

Hurst's new counter-flow device improves boiler efficiency without  increasing the heat transfer surface area and flue gas pressure drop through the boiler.

Integrated inside of the pressure vessel, Hurst's optional counter-flow device is factory-built into the company's innovative 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 conventional fire tube steam boilers, Hurst's new counter-flow device improves boiler efficiency without increasing the heat transfer surface area and flue gas pressure drop through the boiler. Hurst's advanced technology and engineering works 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, Hurst's patented internal counter-flow device captures the lost or waste heat from the hot flue and stack gasses of the boiler. In accordance with patent approval, calculations were performed by computer model of Hurst's counter-flow boiler under typical conditions. Relative to other boilers having traditional designs, tests determined that the device improves boiler efficiency by as much as 3%, depending on working conditions.

Unlike the bulky assembly of a typical external economizer that has separate housing and ductwork in addition to the boiler housing, Hurst's streamlined, internal counter-flow device requires no external housing or support. As a result, boiler room costs can also be further reduced by savings associated with installation, maintenance and labor.
