Abstract: Characteristics of a flame within a turbine or burner are determined based upon ultraviolet, visible, and infrared measurements of the flame. The measurements include a measurement of the amplitute of frequency bands that are indicative of an efficient combustion process, such as those that increase when the flame temperature increases. The measurements also include of the amplitude of frequency bands that are indicative of an inefficient combustion process, such as those that do not vary, increase a relatively small amount, or decrease when the flame temperature increases. The temperature of the flame may therefore be determined accurately, to facilitate efficient operation of the turbine or burner while minimizing polluting emissions. A fiber structure, suitable for remote location of sensors and processing equipment passes energy for several spectra by providing a hollow core that passes infrared energy, in combination with a core of visible-transmissive material that passes visible or ultraviolet energy. Contaminants in the turbine or burner are detected, and a degree of contamination measured, by detection of energy levels for particular wavelengths associated with a respective contaminant.

Abstract translation: 基于火焰的紫外线，可见光和红外测量值来确定涡轮机或燃烧器内的火焰的特征。 这些测量包括指示有效燃烧过程的频带放大器的测量，例如当火焰温度升高时增加的那些。 测量还包括指示低效燃烧过程的频带的振幅，例如不变的那些，增加相对较小的量，或者当火焰温度升高时降低。 因此，可以准确地确定火焰的温度，以便于使污染排放最小化的涡轮或燃烧器的有效运行。 适用于传感器和加工设备的远程定位的光纤结构通过提供透过红外能量的中空芯片与通过可见光或紫外线能量的可见光透射材料的核心相结合，传递几种光谱的能量。 通过检测与相应污染物相关联的特定波长的能量水平来检测涡轮机或燃烧器中的污染物并测量污染程度。

Abstract: A method of detecting an amount of a contaminant in an enclosure, the method comprising: detecting (S7) a first amplitude of energy within a first wavelength band of a first width centered about an emission wavelength of the contaminant, the method characterized by: detecting (S8) a second amplitude of energy within a second wavelength band of a second width larger than the first width, the second wavelength band also centered about the emission wavelength of the contaminant; determining (218) a ratio of the first amplitude of energy to the second amplitude of energy; and comparing (220) the ratio to a known threshold to determine the amount of contaminant in the enclosure.
