Purchasing a new boiler entails a lot of preparation to ensure proper functioning and longevity. Its internal surface usually contains deposits of residual oil, grease, and protective coating which are post-production remains. These deposits should be removed, since contamination lowers the heat transfer rate and can possibly overheat pressure vessel metal. A boil-out chemical will effectively clean these off.
Boil-out chemical is a concentrated mixture of alkaline cleaners and detergents, chelating agents, and inhibitors designed specifically for the cleaning preoperation of industrial boilers and certain water systems. The product is formulated to precondition the exposed metal surfaces, thereby minimizing flash rusting before treatment program starts.
Features and Benefits:
- Assures boiler reliability and cleanliness upon commission
- Effectively removes oil, dirt, and grease
- Assists in loosening mill scales typically found in new equipment
Feed and Control:
Product is usually pumped into the boiler through one of the vents while the unit is being filled with water. Manufacturer’s procedure should then be followed.
Feedrates: 1 to 4 gallons per 100 gallons.
Handling and Storage:
Boil-out chemical is highly caustic, and can produce a violent flash if introduced too rapidly into the water. Protective equipment like goggles, gloves, and laboratory gowns should be worn before handling it.
Store product in a tightly-closed container, away from sunlight. Recommended storage temperature range is 10°C-40°C (50°F-105°F). After chemical is consumed, do not reuse container. Dispose empty container properly, in compliance with federal, state/provincial, and local laws and regulations.
