HeatSponge Economizer Tutorial

This feed water enters an economizer to be heating using flue gas exiting the boiler. A rule of thumb is water temperature will be raised 1 degree for every 4 degrees that the flue gas loses temperature. The water from the deaerator is raised using the heat remaining in the discharged flue gas by use of the economizer.
