Spectroscopic System for Combustion Processes Diagnostic of Gaseous Hydrocarbons

Using the optical spectroscopy methods, where a spectrometer is used as a diagnostic device, is proposed to solve the problem of the combustion processes diagnostic of gaseous hydrocarbons. The results of an experimental study of the spectroscopic parameters characterizing the of combustion process of gaseous hydrocarbons by the methods of emission and laser-induced breakdown spectroscopy are presented. The most intense spectral lines and ranges are determined, and their dependence on the gas/air ratio is given. A concept of constructing a spectroscopic system based on emission and laser-induced breakdown spectroscopy is proposed. This system makes it possible to the combustion processes diagnostic of gaseous hydrocarbons based on the measurement of a set of predetermined spectroscopic parameters.
