| 摘要 |
An optical spectrometer for combustion flame temperature determination includes at least two photodetectors (1,2) positioned for receiving light from a combustion flame and having different overlapping optical bandwidths for producing respective output signals; and a computer (34) for obtaining (136) a difference between a first respective output signal of a first one of the at least two photodetectors with and a second respective output signal of a second one of the at least two photodetectors, dividing (138) the difference by one of the first and second respective output signals to obtain a normalized output signal, and using the normalized output signal to determine (40) the combustion flame temperature. <IMAGE> |
