Abstract

Autour de la paroi interne (5) de l'avant-foyer (4) est monté un serpentin de refroidissement (6) à spires jointives se succédant sur la totalité de la longueur de ce dernier, pour maintenir la température entre 600 et 900 degrés C, l'entrée d'air tertiaire (11) composée de nombreux trous répartis circulairement autour de l'ouvreau (8) et un circuit de soufflage (15) indépendant se termine par des tubes longitudinaux (16, 17) disposés à la partie basse et à l'entrée de l'avant-foyer (4) et du tube-foyer (1), ce qui permet d'obtenir une bonne combustion régulière du charbon pulvérisé.
