چکیده انگلیسی
Research results are presented for an AC electric arc that burns a mixture of steam and air in a three-phase high-voltage plasma torch and can be implemented to produce plasma for plastic waste gasification. The dependences of electric parameters on the ratio of the steam to air mass flows (H2O/air â¼1-6) at an approximately constant total mass flow of the plasma-forming gas are obtained during several experiments. During the experiments, the arc parameters were as follows: voltage drop of 1.0-1.8Â kV, current of â¼28.5Â A and power of â¼52-86Â kW. The thermal efficiency of the plasma torch was â¼94-95%. CCD cameras operating at 4000Â fps were used to determine the average discharge length of â¼798Â mm. Photography with a high shutter speed (1/8000Â s) was used to determine the average arc diameter (â¼4.47Â mm). Arc temperatures were calculated (10,000-11,500Â K) using the thermodynamic equilibrium approach. Experimental results indicate that increases in the steam content of the steam-air plasma lead to a reduction of the arc's temperature and electrical conductivity. Using an equilibrium approach, the main parameters of plasma gasification were estimated: syngas yield (3.62-3.48Â m3/kg), composition (H2 - 55.5-62.5, CO - 32.8-34.1Â vol.%) and energy consumption (11.0-12.3Â MJ/kg).
