Concrete plant boiler scale at two Calgary facilities
Concrete plant boiler scale and biofouling were affecting two concrete batching facilities in Calgary, at North and Railway Street. Chemical dosing was needed regularly, equipment protection was limited, and the dosing sat uneasily with the company’s sustainability policy. From spring 2017 two HydroFLOW® I-120 units were installed on the boiler systems at the two sites, one approach for both. Scale and biofouling were controlled, chemical dosing fell at both sites, and the boilers have been protected for more than six years since. Winter operation puts the boilers under their heaviest load, and the units have needed no attention beyond routine checks.
The Challenges
- Concrete plant boiler scale and biofouling were affecting boilers at two sites
- Chemical dosing was regularly required on the boiler systems
- Equipment protection on the boiler systems was limited
- Chemical dosing conflicted with the company’s sustainability goals
- Both sites needed the same result from the same approach
The Solution
- Units installed: two HydroFLOW® I-120 units across two sites
- Installation point: boiler systems at the North and Railway Street facilities, Calgary
- Installed: spring 2017
- Previous treatment: regular chemical dosing
Both facilities were fitted in the same season, with the two I-120 units installed on the boiler systems across the two sites. The signal disrupts the conditions that bond scale and biofilm to surfaces. With concrete plant boiler scale and biofouling controlled, chemical dosing was reduced at both sites, and they have run on the same maintenance schedule since.
