Municipal solid waste was gasified in the reactor equipped with a DC plasma torch. Produced thermal plasma features outstanding parameters such as very high temperature (approx. 18 000 K) together with low mass flow rate (around 0.3 g/s of H2O + 0.2 g/s of Ar). The plasma torch is mounted to a water cooled reactor that has ceramic 400mm insulation and inner volume of 0.22 m3. There is the inlet of gasified material in the top part of the reactor and the outlet of produced gas in the side of the reactor. Wall temperatures ranged between 900°C and 1 500°C during experiments. Municipal solid waste (plastics 47 %, wood + paper 24 %, textiles 10%, fines 18 %) was gasified at the rate of 20, 40 and 60 kg/h. The sum of hydrogen and carbon monoxide formed roughly 90 % (vol.) of produced gas (the rest was mainly composed of argon, carbon dioxide, methane).
