Abstract

L'invention concerne un brûleur central destiné à un système de brûleur multi-combustibles à lances multiples, comprenant une lance centrale qui comporte un tube interne et un tube externe. Le tube interne et le tube externe forment entre eux un conduit annulaire. Plusieurs lances externes sont disposées autour de la lance centrale. Un dispositif mélangeur en forme d'entonnoir se trouve dans le prolongement du conduit annulaire dans la zone de l'extrémité du tube interne. Ce dispositif mélangeur en forme d'entonnoir comporte dans sa paroi des ouvertures destinées à être traversées par un courant de fluides de combustion. Les lances externes comportent chacune une tuyère percée le long de la surface périphérique latérale d'orifices disposés de manière asymétrique.
