The change in the flame temperature depending on the modes of combustion of solid biofuel has been investigated. A decrease in the flame temperature, as well as an increase in the heat flux density on origination of vibrating combustion has been revealed. The article presents the results of investigation of the emission of radioactive 137Cs with flue gases at different modes of combustion of solid biofuels contaminated by radionuclides in a wide temperature range. In the case of vibrating combustion, a decrease in the emission of radioactive 137Cs with flue gases is noted. A theoretical model of the development of sonic perturbations of the combustion wave and of the influence of the latter on heat transfer characteristics has been developed. The results of the studies allow one to develop recommendations on combustion of a solid biofuel with better ecological characteristics of emissions into the atmosphere and with improved heat-transfer parameters, which improves the efficiency of furnace facilities operating on solid biofuel in heat generators. An empirical-theoretical dependence has been obtained for calculating heat transfer in the Rijke tube during vibrating combustion. A model of calculation of the perturbation amplitude for instabilities in "vessel–tube"-type facilities is proposed.
