Spectrochemical analysis is established as a powerful tool for elucidation of combustion phenomenon. The pur-pose of this article is to explain what spectrochemical method is, and demonstrate how to analyze combustion phenomena. Spontaneous emission spectroscopy for time-resolved temperature profiling and isotope-shift planar laser-induced fluorescence spectroscopy for visualization of steam addition effect are reviewed as examples of study. In addition, recent developments in laser-induced plasma spectroscopy named chemical seeding LIPS are surveyed. Keywords: two-dimensional, spectroscopic analysis, planar laser-induced fluorescence, laser-induced plasma spectroscopy, industrial furnaces
