Abstract
A process for energy- and emission-optimized iron production and an installation for carrying out the process. A first partial amount of a generator gas produced in a melter gasifier is used as a first reducing gas in a first reduction zone. A second partial amount is fed to at least one further reduction zone as a second reducing gas. In addition, after COscrubbing, a partial amount of top gas removed from the first reduction zone is admixed with the generator gas after the latter leaves the melter gasifier, for cooling the generator gas.
