Hurst Boiler's Thermo-Master and Stack-Master are factory-installed internal devices that aid in lowering stack temperatures by utilizing makeup feedwater and exhaust gases as a means to increase overall boiler efficiency. Their unique water-to-water counterflow design partitions off the boiler vessel toward the end of the flue pass. Within this isolated zone, lower-temperature makeup water is injected through strategically placed manifolds. This lower-temperature zone is able to transfer more of the remaining heat from the spent flue gases, enabling the release of its energy to the work load before exiting the system.
