Boiler Treatment Simplified With WaterCare
December 5, 2014
The chemical treatment of smaller boiler units can be confusing and expensive if not understood. Here is a simple guideline to follow for applications using a boiler for steam generation for process or heating use.
Many smaller to mid-sized facilities require steam for process and/or building heating requirements. The most common units are ‘fire-tube’ design with a horsepower rating of 25 HP to 100 HP. Steam delivery is usually at a pressure of 5 psi to 20 psi.
The treatment of these boilers is recommended to prevent corrosion and scale of piping and equipment used in the process. Depending upon the sizing and process, a softener, a feedwater tank, a boiler, and a condensate return tank may be involved. A smaller system may just have a boiler with no return lines.
COVENTYA WaterCare can ‘Keep It Simple.’
For smaller applications, we provide ‘All-In-One’ drum chemical treatments. The make-up water source will dictate what treatment type should be used as follows:
- For systems with good ‘softened’ make-up water quality:
OMEGA TH-7125: phosphate / dispersant sulfite / amine
Dosage: 0.5 gallons per 1,000 gallons of feedwater make-up
- For systems with periodic hardness and/or elevated alkalinity:
OMEGA TH-7127: organic phosphate / dispersant / sulfite / amine
Dosage: 0.2 gallons per 1,000 gallons of feedwater make-up
- For systems with hard water make-up quality or ‘scaled’ systems:
OMEGA TH-7129: chelant / dispersant / sulfite / amine
Dosage: 0.3 to 0.6 gallons per 1,000 gallons of feedwater make-up
