Hot plasma and material mixed structure, it is identical that method is that substance nozzle is mounted on gas-solid down-flow fluidized bed using ECT mixer vias inner walls
Or on different sections, layer 2-3 being divided to be distributed, every layer of 2-50mm, setting angle can be adjusted in entire space, be sprayed in material
Screening stream component is installed, it is therefore an objective to improve radial velocity of the material particles along reaction channel, be penetrated into plasma above mouth
Flow center high-temperature region, expand material jet stream and plasma jet contact area, but and not up to ideal effect, plasma
Body jet stream ablation and washing away makes the loss of screening stream component increase, and since the temperature gradient of plasma jet is larger, with temperature
Degree successively decreases, and vertical height increases the number of plies of substance nozzle, keeps material reaction incomplete, it is easier to form coking material, block anti-
Channel is answered, long-play is unfavorable for.
