Krivosheev S. The determination of gas and solid phase's parameters of the dusted gas streams in the coal energy installation

Dissertation work is devoted to development of the methods of determining parameters of the gas (concentration of components, temperature) and disperse (speed, size, concentration, temperature, residual carbon in the particles) phases of the dusted gas streams. Analytical dependence is found that describes scattering of the laser radiation from the particles, depending on their parameters. The device is constructed and method of its operation is developed, to measure parameters of the fly ash particles in a stream. The problem of describing diffusion of gas being adsorbed when passing capillary is solved for arbitrary change of the capillary wall temperature. Cryogenic adsorption modulator of a gas stream is created to enhance sensitiveness of the mass-spectrometric measurements of harmful components concentration in flue gases. Method of using fluctuation spectroscopy is justified, to determine energy of the reaction of gasification of coal particles and the temperature of gas-reagent. The method of measuring brightness temperature of burning particles is developed from the analysis of fluctuations of radiation intensity scattered by the dusted stream exposed to the rays from the standard source.
