ADDITIVE FOR PREVENTING DEPOSITS AND CORROSION OF HEATING FURNACES OR STEAM GENERATORS, AND METHOD FOR ITS OBTAINING

摘要

An additive is described as preventing deposits and corrosion of heating furnaces or steam generators, which is characterized by the fact that it is a water solution, containing 25 DIVIDED 40 g/l K<+> ions, 60 DIVIDED 80 g/l NO3<-> ions, a maximum amount of 50 mg/l chromium, ethylic alcohol or mono ethylene glycol in a maximum proportion of 35 % wt., 5 DIVIDED 11 g/l NH4<+> ions, and having a pH value 8 and a congealing temperature in the range of -5 DIVIDED -20 DEG C. The method for obtaining this additive comprises dissolution of components, filtration of solutions, homogenization and additivation of the mixture, followed by adjusting its pH to a value equal or greater than 8. The present additive is useful for preventing corrosion phenomena and deposits resulted in furnaces and steam generators, which use any gaseous, liquid or solid fuels.
