The Challenge
- Scale persisted despite softening and chemicals
- Heavy scale coated internal boiler tubes
- Acid cleaning was being considered
- Heat transfer efficiency was reduced by scale
The Solution
One HydroFLOW® i45 unit was installed on the feed water line entering the 60 HP low pressure natural gas steam boiler in August 2013, with existing water treatment remaining active during the six month evaluation. The signal makes existing scale brittle so it breaks away and purges through blow-down while new scale doesn’t form.
