Abstract. The high-temperature heating of carbon-bearing fuels with particle size of 50-200 microns was investigated in order to establish rational and kinetic thermal parameters, their influence on the heat-and-mass transfer and efficiency of thermal reactions in the reaction chamber at a changed specific heat flow qc = 104 ÷ 107 W/m2 and gas temperature Тк = (2÷6)·103K. The thermal parameter influence on the solid fuel gasification process was determined on the example of coal particles and water vapor heating at convective and radiant heat transfer. The calculation results were compared, and it was concluded that influence of radiative heat transfer prevailed in the total heat flow in plasma reactor when Тк > 5·103 K. Volume of the reaction chamber and its operation are calculated with taking into account thermal and kinetic parameters of the fuel high-temperature heating. It is shown that a process of the fuel thermal transformations is effective at temperature Тк ≤ 3000 K in the plasma-chemical reactor of the combined type.

Keywords: carbon-bearing environment, chamber, heating, temperature, kinetic parameters, thermal conversion, volume, efficiency of the process.
