Abstract: Disposal of carbon-containing wastes in a plasma furnace is studied. The influence of the plasma generator power on gasifier efficiency is found for different waste humidities; dependences of specific energy consumption on the waste humidity and air flow rate are obtained. Experimental results are in good agreement with calculations. Sawdust gasification is performed in an electric-arc furnace with an additional heater. The composition of the resultant synthesis gas is analyzed, and the heater performance is determined. It is demonstrated that burning some part of the resultant gas in the heater allows energy consumption to be reduced by 20–25%, as compared with purely plasma gasification.

Keywords: arc discharge, plasma gasifier, electric furnace, carbon-containing wastes, synthesis gas, heater.
