摘要：The analysis of the process of thermal transformations of carbon environment at high temperature (T = 2000 K) processing in a chamber of a plasma-jet reactor with the use of a water vaporizer as an oxidizer is done. The influence of heat exchange parameters on the heating of coal particles of different sizes is established. The method of mathematical modeling of the process of conversion of dispersed carbon raw materials in a stream of water plasma at a temperature in the reaction chamber Tg = 2000 - 5000 K was developed. The technique allows to determine the influence of thermal and kinetic parameters on the process of heat exchange between coal particle and a steam-plasma environment. A conversion time of a coal particle into a gaseous state is determined. It is the time that laid the foundation for calculating the main geometric and regime parameters of the reactor. The expediency of increasing the temperature of the gases in the reactor Tg = 3000 K is proved. This determines the minimum time for conversion of carbon under the combined influence of convective and radiation heat exchanges.
