SYSTEM FOR ELECTROLYTICAL TREATMENT FOR PROTECTION AGAINST CORROSION AND DEPOSITS OF SCALE IN WATER BOILERS

摘要

The invention relates to a system for electrolytical treatment for the protection against corrosion and deposits of scale in water boilers, by using protection anodes and an external direct current source. The protection anodes (15) are uniformly distributed lengthwise of the water headers or in the covers thereof and are grouped connected to two or more direct current sources adjustable so that each anodes group is subjected to a protection electric potential correlated with the water temperature in the protected zone.
