Patent ID: 8257450

Claim:
A method to inhibit corrosion of a combustion unit combusting a fuel, wherein the corrosion is caused by combustion byproducts, said method comprising adding to the combustion a corrosion-inhibiting amount of a manganese source, wherein the manganese is selected from the group consisting of methyl cyclopentadienyl manganese tricarbonyl, cyclopentadienyl manganese tricarbonyl, bis-cyclopentadienyl manganese (manganocene), bis-alkyl cyclopentadienyl manganese, alkyl cyclopentadienyl manganese tricarbonyl, organic manganese tricarbonyl derivatives, alkyl cyclopentadienyl manganese derivatives, and combinations and mixtures thereof, the corrosion occurring at a temperature below 250° C. during the operation of the combustion unit, and wherein the combustion unit is selected from the group consisting of non-evaporative stationary burners, power plant generators, power plant furnaces, boilers, furnaces, plasma burner systems, and plasma arc combustion units.
