Abstract

Le procédé comporte l'injection simultanée d'un combustible auxiliaire et d'un gaz comburant dans un haut fourneau. On injecte le gaz comburant sous la forme d'un jet central et on injecte le combustible auxiliaire sous la forme d'un jet périphérique entourant, au moins partiellement, le jet central de gaz comburant, Le jet périphérique peut être un jet unique ou être constitué d'une pluralité de jets disposés en couronne autour du jet central.
