TECHNOLOGY OF RADIATION AND PLASMA PROCESSING OF COAL
ABSTRAKT
Radiation and plasma technology for coal processing is proposed. Thermodynamic and experimental investigations of plasma processing of bituminous coal with or without its pre-activation by an electron beam were performed. A significant positive effect of electron pre-activation of pulverized coal fuel on the yield of synthesis gas during its processing has been found. The experiments were conducted in a plasma gasifier with the nominal power 100 kW. The measurements of material and heat balances of the process gave the following integral indicators: the mass-average temperature 2200−2300 K and the carbon gasification rate 82.4−83.2%. The yield of synthesis gas during thermochemical conditioning for combustion of untreated coal dust was 24.5%, whereas in the case of coal electron-beam activation the yield of synthesis gas reached 36.4%, which is by 48% higher.
