ABSTRACT:
A process and device for removing heavy metals and compounds containing heavy metals from waste gas of a metallurgical vessel which is charged with materials posing disposal problems. The flue gas collecting in the metallurgical vessel is sucked out of the vessel as a main gas flow and cleaned in a gas cleaning system. The flow of cleaned gas is guided to an after-burning device. A portion of the clean flue gas is diverted frown the main gas flow leading to the after-burning device. The diverted flow portion is cooled and guided back to the main flow of flue gas where it is mixed with the flue gas before the main flow of flue gas enters the gas cleaning system.
