Abstract:
1. An installation for granulating slag from a blast furnace or a smelting reduction plant, the installation comprising: a granulation device configured to granulate the slag; a slag channel configured to deliver the slag to the granulation device; an extractor hood positioned over the slag channel and configured to discharge flue gas; a downstream granulation tank positioned downstream from the granulation device in a slag movement direction and configured to hold a granule/water mixture; a condensation device flow connected to the granulation tank and including a water feed and a device configured to inject water into the condensation device; and a discharge line leading from the condensation device and configured to discharge vapors and gases containing H wherein the first point is positioned at a first distance from the extractor hood, and the slag channel is configured to pass the vapors and gases in a direction counter to the direction of the slag flow so as to heat and combust H
