The gas dynamic-thermal-concentration fields and evaporation process of quartz particles in the TICP torch of argon–hydrogen plasma have been studied. The effects of different methods of supplying hydrogen on the hydrogen concentration and gas temperature distributions, as well as on the vortex flow patterns have been discussed. The particle injection conditions in the pure argon and argon–hydrogen plasma have been determined. The dependences of the axial gas temperature and velocity distributions on the hydrogen volume fraction, flow rate of central gas and particle feed rate have been established. The effect of hydrogen volume fraction and different methods of supplying hydrogen on the evaporation degree of quartz particle in the TICP torch has been determined. The influences of the particle injection conditions (flow rate of central gas, probe tip position and injection patterns) on the evaporation degree in the TICP torch have also been evaluated. The specific heat cost for ...
