Paper Abstract

This article reflects the application of optical spectroscopy methods in automatic control systems of combustion process in thermal power plants and different transport systems engines. Forming of controlled states and error signals is carried out by means of the multichannel optical spectrometer where the spectral decomposition is based on a resonance phenomenon in the narrow-band optical interference filters on the measurement data of the electromagnetic radiation spectrum as one of the results of the combustion process. This device carries out the contactless spectrum analysis in the predetermined optical ranges using a set of narrow-band interference optical filters tuned to certain wavelengths and fiber-optical system using for analyzed optical radiation transmitting. This radiation carries the spectroscopic information about the controlled combustion process. Using fiber-optical system excludes the negative impact of various extreme factors on the spectrometer operation as part of the error signal forming system. The special principle of the developed multichannel optical spectrometer construction allows applying not only one optical fiber but a fiber bundle. That increases the sensitivity of the device without reducing of its resolution. The novelty of the developed device is confirmed by the patent of the Russian Federation. This paper presents the results of the development of the multichannel optical spectrometer set-up and the results of its experimental research. The experimental research is carried out to determine the spectral line of copper (Cu) when burning copper powder.
