Boiler Cleaning Chemicals

What is a boiler blow-out?

Boiler blowout is the cleaning of boiler flues from scale and impurities using a blast of steam.

Why is it important to perform boiler blow-out regularly?

When setting up a new boiler, it is very important to perform a boil-out procedure. 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.

What is Boiler Boil-Out Q-ABC?

Boiler Boil-Out Q-A-BC is a concentrated mixture of alkaline cleaners, detergents, chelating agents, and inhibitors formulated specifically for cleaning boiler preoperational and other water systems. It preconditions metal surfaces and minimizes flash rusting. Its active ingredient is sulfamic acid.

What is sulfamic acid?

Sulfamic acid is a white, non-hygroscopic crystal which is soluble in water, ether, acetone, and methanol. It is a strong acid in both aqueous solution and anhydrous liquid ammonia. Sulfamic acid has a chemical formula of H2NSO3H. It is also called amidosulfonic acid and amidosulfuric acid.

What are the properties of sulfamic acid?

• Molar mass: 97.09 g/mol

• Boiling point: 247°C

• Melting point: 205°C

• Density: 2.15 g/cm3

• Water solubility: 213 g/L (20°C)

• Partition coefficient: -0.95 pK0W

• Vapor pressure: 0.006 (20°C)

• Vapor density: 3.3 (air=1)

• Heat of fusion: 11.9 kJ/mol

• Heat of combustion: -1530 kJ/mol

How do you feed Boiler Boil-Out Q-ABC to the system?

When setting up a new boiler, it is very important to perform a boil-out procedure. Its internal surface usually contains deposits of residual oil, grease, and protective coating which are remains from post-production. 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.

Boiler Boil-Out Q-A-BC is a concentrated mixture of alkaline cleaners, detergents, chelating agents, and inhibitors formulated specifically for boiler preoperational cleaning and other water systems. Metal surfaces are preconditioned and flash rusting is minimized.

Features:
*  Assures boiler reliability and cleanliness at commissioning
*  Effectively removes light oils and greases
*  Assists in loosening mill scales typically found in new equipment

Product Feed and Control:
Normally, Q-A-BC is pumped into the boiler through one of the vents while the unit is being filled with water. Manufacturer’s procedure for boil-out should then be followed.
Federates: 1 to 4 gallons per 100 gallons

Handling and Storage:

Keep product in a tightly closed container. Store it in a cool, dry place and away from direct sunlight. Recommended storage temperature is 10° - 40° C (50° - 105° F). Do not reuse container and dispose it in compliance to federal laws.
