⚡ Continuous Surface Blowdown % = Feedwater TDS / [Boiler TDS - Feedwater TDS]

Boiler Surface Blowdown & Heat Recovery Calculator

Model automatic continuous surface blowdown and flash steam heat recovery for industrial boilers under ASME Guidelines for Water Quality: calculate required blowdown percentage based on Total Dissolved Solids (TDS conductivity limits), size flash tanks and blowdown heat exchangers to recover 90% of waste thermal heat, and fuel savings yields.
