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.The process involves the simultaneous injection of an auxiliary fuel and an oxidizing gas into a blast furnace. The oxidizing gas is injected in the form of a central jet and the auxiliary fuel is injected in the form of a peripheral jet surrounding, at least partially, the central jet of oxidizing gas. The peripheral jet can be a single jet or be consisting of a plurality of jets arranged in a ring around the central jet.
