Elimination of incrustations in heaters and its linking with their composition. Case study: the 1988 season at Camilo Cienfuegos combine



ATAC, Revista de la Asociacion de Tecnicos Azucareros de Cuba 50(1): 43-47



During the offseason, strong scale was found in mixed juice heaters; it had survived the normal cleaning scheme through the season, remaining in the tubes as an insulating layer decreasing heat transfer and thermal efficiency. It was shown to consist of 45-50% Ca phosphate, 25-30% CaCO3, 14% organic matter, <10% silicates, and traces of Fe salts and MgCO3. It was confirmed that neither NaOH nor NaHF2 (hot or in cold acid) had much effect.
