It is aimed at using in the diagnostics of the efficiency of industrial devices based on the principle of pseudofluidization of granular material by an ascending gas flow, for example, that one of roasting furnaces, drying machines, heat generators. The method consists in introducing a solid into the pseudofluidized layer, creating a predetermined temperature difference between the solid and the pseudofluidized layer. For a given duration of time, the instant temperature of a given part of the solid surface is recorded. A spectral analysis of the pulsations of the measured temperature of the solid surface part is performed. For spectral analysis, a fast Fourier transform is used, and the spectral analysis results are used to obtain the distribution of the spectral power density of temperature pulsations over the spectrum. From the obtained distribution of the power spectral density, the frequency of the low-frequency harmonic of these pulsations is found, and the desired thermal conductivity is found by calculation. The proposed method, in contrast to analog methods, is easily implemented in the operating conditions of large industrial devices, has a wider range of applications with simultaneously high achievable measurement accuracy.
