Method for producing reduction gases consisting essentially of carbon monoxide and hydrogen

Abstract

A single heat method of producing reduction gases which consist essentially of carbon monoxide and hydrogen for ore-reducing processes, comprises, directing a coal and water suspension into a reactor to generate combustion gases under pressure having a temperature in the range of from 1300.degree. C. to 1500.degree. C. and mixing the combustion gases immediately after they are formed with reduction furnace waste gases which have a temperature in the range of from 100.degree. C. to 500.degree. C. The mixed gases are then directed through a water seal separator to separate and quench slag particles and the slag particles are removed with water from the gas stream. The pressure gases are mixed with the waste gases in a proportion of from 1:0.5 to 1:2.0. The resultant gases after purification and hydrogen sulfide scrubbing are directed back into the ore-reducing process and the quenched slag particles are fused to larger size agglomerates and are carried out of the gas stream and taken up in water.
