Some optical phenomena observed in the flames from the burning of flammable vegetation materials and ethyl alcohol are analyzed. Recommendations on the optimal spectral bands for temperature measurements of hot objects obscured by flames are given. Frequency spectra of temperature pulsations in flames are obtained, thus revealing a spatial structure in the flow of combustion products, as well as the degree of turbulence in a high temperature fluid medium.
