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 |
Product Code: RXSOL-25-5006-025
The use of Disodium phosphate treatment in BOILER converts calcium hardness into soft, non-adherent sludge that is easily removed by blowdown.
Sampling And Testing
A sample of boiler water should be drawn for analysis daily. The sample should always be taken from the same point after blow down, cooled and tested immediately. Follow the Rxsol Hardness Test Kit instructions and fill the Boiler Water Log Form according to result results. It is important that regular testing is carried out to ensure levels of treatment are correct.

Phosphate/pH relationship recommended to control boiler corrosion. Different forms of phosphate consume or add caustic as the phosphate shifts to the proper form. For example, addition of monosodium phosphate consumes caustic as it reacts with caustic to form disodium phosphate in the boiler water according to the following reaction:
| NaH2PO4 | + | NaOH | ® | Na2HPO4 | + | H2O |
| monosodium phosphate | sodium hydroxide | disodium phosphate | water |
Conversely, addition of trisodium phosphate adds caustic, increasing boiler water pH:
| Na3PO4 | + | H2O | ® | Na2HPO4 | + | NaOH |
| trisodium phosphate | water | disodium phosphate |
sodium hydroxide |
