Combustion processes are characterized by some parameters, including spectroscopic ones. Therefore, it is proposed to use the methods of applied optical spectroscopy to solve the task of diagnosing a combustion process of gaseous hydrocarbon fuel. In this case, the control device is a spectral–selective device that scans optical radiation as a signal carrying spectroscopic information about the combustion process. It can replace most of the control – measuring equipment located at the place of measuring. This device executes spectral measurements in specified areas of the optical range using a set of narrowband interference optical filters tuned to the specific wavelengths. The modernity of the device is confirmed by the Russian Federation patent. In this research, an installation was developed, which includes a burner and a gas supply system. An analysis of the spectroscopic informative properties in the emission spectrum of the flame arising from the combustion of hydrocarbon fuel was carried out. The experiment was accomplished by using the Ocean Optics USB2000 + spectrometer. The results of this experiment provided comprehensive information on the wavelength values of the optical filters are needed. These filters are part of the spectral–selective diagnostic device. Then a prototype of the spectral selective device for a combustion diagnostic was developed and assembled. In this paper, the results of experimental research of this device and a comparative analysis with the Ocean Optics USB2000 + spectrometer within the case of solving the problem of gaseous hydrocarbon fuel combustion diagnostics are also provided.
