Blowdown Heat Recovery | CleanBoiler.org

Blowdown Heat Recovery Introduction. All steam boilers must blowndown to reduce the amount of TDS in the boiler water. See Blowdown However, along with the solids, boiler chemicals and thermal energy is lost; blowdown heat recovery systems cannot recover the chemicals, but they do recover up to 90% of the heat energy that would otherwise be lost down the drain.
