1. A method of evaluating the flame state of a burner flame, comprising:obtaining operating data from a burner flame; constructing a symbol sequence histogram from said operating data; comparing said symbol sequence histogram to a pre-existing library of symbol sequence histograms to identify a non-optimal flame state of said burner flame; and identifying a root cause of said non-optimal flame state. 2. The method of claim 1, wherein said non-optimal flame state is selected from the group consisting of an edge-lifted flame, a sporadically detached flame, a fully detached flame, a flaring flame, a pancaked flame, a flapping flame, and a slugging flame.3. The method of claim 1, further comprising analyzing said operating data using a technique selected from the group consisting of conventional statistical analysis, Fourier transform analysis, cluster analysis, temporal irreversibility analysis, and combinations thereof.4. The method of claim 1, further comprising computing a temporal irreversibility function from said operating data; and wherein said comparing further comprises comparing said temporal irreversibility function to a pre-existing library of temporal irreversibility functions.5. The method of claim 1, wherein said identifying comprises correlating said non-optimal flame state to a process operating parameter.6. The method of claim 1, wherein said identifying comprises correlating said non-optimal flame state to a piece of operating equipment.7. A method for optimizing a burner flame, comprising:obtaining operating data from a burner flame; constructing a symbol sequence histogram from said operating data; comparing said symbol sequence histogram to a pre-existing library of symbol sequence histograms to identify a non-optimal flame state of said burner flame; identifying a root cause of said non-optimal flame state; and reducing the effect of said root cause on said burner flame. 8. The method of claim 7, wherein said non-optimal flame state is selected from the group consisting of an edge-lifted flame, a sporadically detached flame, a fully detached flame, a flaring flame, a pancaked flame, a flapping flame, and a slugging flame.9. The method of claim 7, further comprising analyzing said operating data using a technique selected from the group consisting of conventional statistical analysis, Fourier transform analysis, cluster analysis, temporal irreversibility analysis, and combinations thereof.10. The method of claim 7, further comprising computing a temporal irreversibility function from said operating data; and wherein said comparing further comprises comparing said temporal irreversibility function to a pre-existing library of temporal irreversibility functions.11. The method of claim 7, wherein said identifying comprises correlating said non-optimal flame state to a process operating parameter.12. The method of claim 7, wherein said identifying comprises correlating said non-optimal flame state to a piece of operating equipment.13. The method of claim 7, wherein said reducing comprises controlling process operating parameters based upon said root cause.14. A method of monitoring the operating state of a burner flame, said method comprising the steps of:obtaining data on the operating state of the burner flame; and analyzing the data with symbol sequence techniques to determine the operating state of the burner flame in which the operating state of the burner flame is a unsteady fuel feed flame. 15. A method of monitoring the operating state of a burner flame, said method comprising the steps of:obtaining data on the operating state of the burner flame; analyzing the data with symbol sequence techniques to determine the operating state of the burner flame; and computing a temporal irreversibility function from the data in which the operating state of the burner flame is a unsteady fuel feed flame.
