ABSTRACT:
Pollutant-containing gases which are generated in a steel-making and/or coking plant are mixed with fresh air in at least one stream and passed through an incandescent bed of minerals, e.g. the sintering cake of an ore-sintering furnace. The resulting gases are then subjected to gas cleaning in at least one filtering or washing station.
