Abstract

The results of studies of the heat exchange between a plasma flow and walls in 180 kW reactors cylindrical and conical mixing chambers provided with three d.c. plasma torches are represented. The three-dimensional model of plasma jet mixing is developed. The calculations are compared with spectral data for the radial temperature distribution of the plasma flows. The review of plasma technologies with the use of tree-jet reactors is performed.
