💧 Blowdown Heat Exchangers (Preheating Cold Make-Up Water, TDS Scale Control)

Boiler Blowdown Heat Recovery Calculator

Size continuous surface blowdown heat recovery packages (flash separator + plate heat exchanger) for industrial steam boilers: calculate recoverable heat from high-TDS boiler water blowdown (cooling 350°F blowdown to preheat incoming cold 55°F make-up water), calculate annual fuel dollar savings, and boiler room energy efficiency margins.
