Abstract (en)

[origin: US2004159184A1] Methods and compositions for inhibiting corrosion of metal surfaces in a furnace system are disclosed. In one aspect of the invention, pulverized coal is burned as fuel in the presence of a copper ion catalyst/combustion aid. Corrosion is inhibited in these systems by the use of a blend of primary aminoalcohol such as 2-aminoethanol, tertiary aminoalcohol such as triethanol amine, and boric acid or water soluble salt form of the acid.
