The continuous evaporation inside a steam boiler causes the concentration and accumulation of salts and dissolved particles of the water it contains. When saturated, these particles fall to the bottom of the boiler and create "sludge" at its bottom.
To prevent impurities in the form of sludge and incrustations from settling and adhering to the walls or bottom of the boiler, which could cause a problem by avoiding the cooling of the tubes and combustion chamber, manual or automatic purges are carried out every 1, 2, 4 or 8 hours depending on the concentration of the feed water.
Many ATTSU boilers incorporate an automatic purge system to ensure optimum operation of the supplied steam boiler and optimize equipment life.
