It is a well - balanced blend for boiler water treatment products, resulting in a scale and corrosion control by one shot operation. A unique one-step Boiler treatment liquid to control the formation of rust and scale in low pressure and auxillary boilers with working pressure up to 20 bars.
Basic Boiler System Schematic
Below is a summary of problems associated with the common impurities in water and solutions to each problem.
List Of Problems Caused By Impurities In Water
Impurity (Chemical Formula)
Problems
Common Chemical Treatment Methods
Alkalinity (HCO3-, CO32- and CaCO3)
Carryover of feedwater into steam, produce CO2 in steam leading to formation of carbonic acid (acid attack)
Neutralizing amines, filming amines, combination of both, and lime-soda.
Hardness (calcium and magnesium salts, CaCO3)
Primary source of scale in heat exchange equipment
Lime softening, phosphate, chelates and polymers
Iron (Fe3+ and Fe2+)
Causes boiler and water line deposits
Phosphate, chelates and polymers
Oxygen (O2)
Corrosion of water lines, boiler, return lines, heat exchanger equipments, etc. (oxygen attack)
Oxygen scavengers, filming amines and deaeration
pH
Corrosion occurs when pH drops below 8.5
pH can be lowered by addition of acids and increased by addition of alkalies
Hydrogen Sulfide (H2S)
Corrosion
Chlorination
Silica (SiO2)
Scale in boilers and cooling water systems
Lime softening
