Abstract

Le brûleur comporte un corps (1) fermé par une plaque d'extrémité (2), ainsi que des moyens servant à amener d'une part un combustible solide et d'autre part un gaz oxydant et débouchant dans cette plaque d'ex­ trémité. Les moyens pour amener le combustible solide consistent en un conduit central (3) disposé suivant l'axe longitudinal du corps de brûleur (1), et les moyens pour amener le gaz oxydant sont constitués par une pluralité de conduits périphériques (4) disposés autour du conduit central (3). De préférence, le conduit central (3) se termine par un canal (5) présentant intérieurement un profil longitudinal divergent et au moins un des conduits périphériques (4) comporte une partie terminale (7) présentant intérieurement un profil longitudinal en tuyères de Laval.
