Claims
- 1. A method of inhibiting corrosion in a flame reaction including an alkali metal comprising:
introducing an 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.
- 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 additive includes Mo.
- 5. The method of claim 1 wherein the noncorrosive product comprises a polymolybdate of the alkali metal.
- 6. 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.
- 7. 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.
- 8. The method of claim 1 wherein the additive includes Mo and wherein the amount of atomic Mo in the additive is at least 2 times as much as the amount of atomic metal alkali in the flame reaction.
- 9. 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.
- 10. 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.
- 11. The method of claim 1 wherein the flame reaction includes sulfur.
- 12. The method of claim 1 wherein the flame reaction includes chlorine.
- 13. A composition of matter used to inhibit metallic corrosion resulting from a flame reaction which includes an alkali metal comprising an additive for introduction in the flame reaction, which additive forms a noncorrosive product with the alkali metal which noncorrosive product is more chemically stable than sulfates of the alkali metal in which flame reaction the noncorrosive product is deposited onto cooler metal structures in or proximate to the flame reaction.
- 14. The composition of matter of claim 13 wherein the alkali metal is Na.
- 15. The composition of matter of claim 13 wherein the alkali metal is K.
- 16. The composition of matter of claim 13 wherein the additive includes Mo.
- 17. The composition of matter of claim 13 wherein the corrosive product comprises a polymolybdate of the alkali metal.
- 18. The composition of matter of claim 13 wherein the additive comprises ammonium paramolybdate, molybdenum oxides, any organo-molybdenum compound, or any other available alkali-free molybdenum salt.
- 19. The composition of matter of claim 13 wherein the additive includes Mo and wherein the amount of atomic Mo in the additive is at least 2 times as much as the amount of atomic metal alkali in the flame reaction.
- 20. The composition of matter of claim 13 wherein the flame reaction is produced by combustion of a fuel and wherein the additive is mixed in with the fuel prior to combustion.
- 21. The composition of matter of claim 13 wherein the flame reaction is produced by combustion of a fuel and wherein the additive is injected into the combustion.
- 22. The composition of matter of claim 13 wherein the flame reaction includes sulfur.
- 23. The composition of matter of claim 13 wherein the flame reaction includes chlorine.
