Boiler Blowdown Heat Recovery - michaelsenergy.com

Boiler blowdown heat recovery can take many forms depending on your specific boiler plant. The simplest and least expensive option is a single heat exchanger that all of the blowdown is run through to preheat the incoming make-up water. More complicated systems can include flash tanks or heated water storage tanks, depending on the facility
