The paper discusses problems, which arise during monitoring of combustion process in the industrial power boilers. The light-guide device for flame monitoring in industrial conditions is described. Wavelet transformation was used for signal analysis. The sensitivity of Daubechies and Coiflet wavelets to changes of a flame pulsation signal has been tested.

Key words: flame, light-guide, wavelet transformation, sensitivity
