SCALE
Scale is an extremely hard substance created when mineral salts come out of solution as their solubility drops with a rise in water temperature. Scale-forming salts adhere directly to heating surfaces forming layers of insulation on the metal substantially decreasing its heat transfer efficiency.
While 1/16th-inch thickness of scale in a fire tube boiler will increase fuel consumption by 12.5% — any accumulation is a problem. Scale results in metal fatigue/failure causing overheating, energy waste, high maintenance costs and unnecessary safety risks.
Impurities dissolved in BFW (Boiler Feed Water) can form scale by precipitation directly on the metal surface of the boiler or, when the impurities are in the form of sludge or suspended matter, they can deposit on the tube surfaces. In addition to causing overheating of boiler tubes, boiler scale can cause under deposit corrosion.
The basic approach in preventing boiler scale and in counteracting problems associated with deposit formation involves the following:
--Maintaining boiler water phosphate or chelant, alkalinity, and oxygen scavenger at acceptable values to minimize deposition and to prevent corrosion of boiler metal. Preventing corrosion in the system, which generates scale-forming products, by removal of the oxygen from the feed water and by holding the feed water pH between 8.2 and 9.5.
--Preventing excessive corrosion products from entering the feed water via the condensate by reducing carbonate and bicarbonate alkalinity in the feed water, and/or by using neutralizing or filming amines as corrosion inhibitors, as required, preventing corrosion in the condensate system.
PRODUCT CHARACTERISTICS
1. Effective to prevent the deposits and scale
2. Particularly useful for the on-line removal of existing
DOSAGE & FEEDING
The type of Boiler, quality of water and other relevant factors determines dosage. ALBATROSS will provide technical assistance and will suggest particular product, its dosage, in accordance with your plant operating conditions and quality of water.
BLOWDOWN
It is essential to blowdown the boiler at regular intervals to ensure removal of sludge from the system. This will also prevent the total dissolved solids from exceeding the prescribed limits. The frequency of blow down will depend upon the quantity of hardness entering the boiler through feed water.
HANDLING
Avoid contact with skin, eyes & clothes. In case of contact wash with plenty of water.
