Abstract

The mathematical model of the furnace charge particles melting in a high-temperature melter with submersible burning of mix natural gas and air is developed. For finding rate of additional layer formation on a surface of initial particle — wall accretion and melting rate of the resultant particle formed owing to this process is used the approach guaranteeing maintenance in each timepoint balance between the amount of heat which came into a particle as a result of contact with a melt, and the amount of heat accumulated by a particle of the current radius. The software is elaborated for the calculation of the furnace charge melting process for particles of different sizes and diverging in their thermophysical properties and the heat exchange conditions with the melt. Analysis of the numerical experiment results is presented. Bibl. 6, Fig. 7, Table 1.
