Abstract

Advanced approach based on a new generation of equipment including DC plasma torch with an interelectrode insertion and distributed ('diffusion') arc attachment on an anode surface providing an axially symmetric plasma jet outflow, and radial−annular slit injection of pulverized coal into a plasma flow are presented. The approach proposed is very attractive when creating the laboratory and model small-scale experiments as well as for industrial application of plasma assisted fuel oil free ignition and stabilization of combustion of the pulverized coal The results of model experiments with using the approach developed are under discussion.
