SINOPSIS

The influence of chemical reactions on the interactions between a plasma jet and small particles (ds < 500 μm) has been investigated.
The rate of particle temperature increase has been found based on the energy balance between the plasma and particles. Usually the following losses of energy are considered: a) radiation, b) melting, c) heating of vapor cloud, d) vaporization. However the chemical reactions can result in large correction in the balance of energy between the particles and plasma. Exothermic reactions are a new source of energy while endothermic ones result in an energy loss.
The chemical reactions for particles at high temperature (when intensive evaporation takes place) occur in the boundary layer surrounding particles ; for particles with temperature close or below melting temperature - at the surface of particles.
Addition of exothermic reaction energy to the particle energy balance is also strongly dependent on the gas flow rate controlling the amount of reactive gas in the boundary layer.
This work presents the analysis of the influence of energy of chemical reactions on the energy balance in plasma-particle system.
