METALLURGICAL APPLICATION OF HYDROGEN-CONTAINING GASES PRODUCED BY THE PLASMA COAL-GASIFICATION PROCESS AT AN ENVIRONMENTALLY CLEAN THERMALPOWER-STATION

The work described in this paper deals with the experimental data of i nvestigations on syngas production by using the plasma coal gasificati on process: H-2-50%, CO-48%, (H2O + CO2) < 2% and application of the g as produced for iron reduction. General schemes of power technological processes, including power and heat production processes simultaneous with syngas production at an environmentally clean thermal power stat ion by using a combined coal treatment process in a plasma thermic rea ctor are investigated. The above-mentioned process allows us to reduce by 10 times air pollution with nitrogen and sulphur oxides when produ cing power. The possibility of considerable capital investment saving in the production and its infrastructure is shown on the base of syste m analysis. Methods of syngas application in blast furnace or direct r eduction and methods of all-round ash and slurry utilization are revie wed.
