Abstract
ABSTRACT For resource utilization of hazardous waste, plasma gasification is considered as a promising technology for sustainable utilization of hazardous waste (HW). In this work, the inlet temperature is set at 400K and the inlet velocity is set at 15 m/s.The Eulerian model is used to numerically simulate the temperature and velocity fields, as well as the distribution of product components (CO, CO2, H2O, H2) in the plasma gassistor under specific conditions. Ansys Fluent software was used to carry out three-dimensional simulation of different material entrances and plasma flares with different injection directions, and to carry out the optimization design of plasma gasification furnace structure. The best structure form was selected by comparing and analyzing the optimized working conditions. The results show that the internal combustion condition is the best when the material inlet is in the side tangential direction and the plasma flare is in the horizontal Angle of 23°.
