Claims
- 1. A method of inhibiting corrosion in a flame reaction including an alkali metal comprising:introducing at least one alkali-free molybdenum salt additive in the flame reaction, which additive forms a noncorrosive product with the alkali metal which is more chemically stable than sulfates of the alkali metal; and depositing the noncorrosive product onto cooler metal structures in or proximate to the flame reaction; with the proviso that the level of molybdenum is twice or more that of the alkali metal in the specific flame environment based on atomic ratios.
- 2. The method of claim 1 wherein the alkali metal is Na.
- 3. The method of claim 1 wherein the alkali metal is K.
- 4. The method of claim 1 wherein the noncorrosive product comprises a polymolybdate of the alkali metal.
- 5. The method of claim 1 wherein the additive is added to the flame reaction in a furnace, boiler, turbine or any combustion apparatus utilizing a fossil, syn-, or biofuel.
- 6. The method of claim 1 wherein the additive comprises ammonium paramolybdate, molybdenum oxides, any organo-molybdenum compound, or any other available alkali-free molybdenum salt.
- 7. The method of claim 1 wherein the flame reaction is produced by combustion of a fuel and wherein the additive is mixed in with the fuel prior to combustion.
- 8. The method of claim 1 wherein the flame reaction is produced by combustion of a fuel and wherein the additive is injected into the combustion.
- 9. The method of claim 1 wherein the flame reaction includes sulfur.
- 10. The method of claim 1 wherein the flame reaction includes chlorine.
