Water quality monitoring

Water treatment of a boiler is fundamental for ensuring a lasting life without operational problems, important repairs and accidents. From hard water to soft it is the one that has a high mineral level, particularly magnesium salts and calcium.

  • pH represents the acidic or alkaline features of water, therefore its control is essential for preventing corrosion problems (low pH) and deposits (high pH)
  • Hardness. Water hardness mainly quantifies the amount of ions of calcium and magnesium in the water, which favor the appearance of deposits hard to remove from heat transferring surfaces in a boiler
  • Oxygen. Oxygen present in water favors corrosion in the metallic elements of a boiler. Pressure and temperature increase the speed in which corrosion is produced

Water analysis

Combustion efficiency and emission monitoring

Enviromental laws in each country established the limits of air polution generated by a boiler or furnace that must be monitorating to accomplish regulations.
