Abstract:
1. A method for measuring spatial temperature distribution of a flame, comprising: (a) providing a flame having a height dimension and a width dimension; (b) positioning a discrete length of an optical fiber within the flame so that the optical fiber produces thermally emitted light which is transmitted along the optical fiber; (c) creating relative movement of the optical fiber and the flame in such a way that the optical fiber is exposed to a number of different areas along the height and the width of the flame; (d) measuring the power of the thermally emitted light produced by the optical fiber at each of said number of different areas along the height and width dimensions of the flame, said power measurements being proportional to the spatial temperature distribution of the flame at said discrete length of the optical fiber whereby the spatial temperature distribution of the flame may be determined.
