Abstract | Regularities of thermal zones development were established on the basis of experimental investigations of temperature fields in the cross section of mine aggregates. Calculated values of ratios of heat capacities of gas and charge flows have shown the presence of areas with average melting conditions, increased activity of gases and low intensity of smelting processes. Usage of acoustic field energy with focusing of sources of the given power sounds in the fuel burning region corresponds to the changing of activity of thermal and physical-chemical processes in the selected areas. Acoustic intensification of process led to a qualitative change of melting indices with increasing of furnace capacity and heat efficiency, and decreasing of dust entrainment and labor effort for purification of working space from the crusts. |
