Abstract

The invention relates to the implementation of processes for the direct reduction of different mineral raw materials and is intended to solve the common problems surrounding the practical implementation of large-scale industrial processes for the gasification of coals, including low-grade lignites, and also oil shales and peat, without the production of carbon dioxide emissions. It is also intended to produce fundamentally new industrial boilers for the large-scale production of heat and electrical energy without greenhouse gas emissions. The invention is based on using the effect of forming plasma by means of pulsed electrical discharges that pass through electrically conducting flows of a suspension produced from a basic, preprocessed mineral raw material mixed with finely ground coke or another carbonaceous substance, and also by means of additional electrical discharges initiated by laser beams with the corresponding use of an external pulsed source of high voltage.
