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.Around the internal wall (5) of the pre-hearth (4) is mounted a cooling coil (6) with contiguous turns successive over the entire length of the latter, to maintain the temperature between 600 and 900 degrees C, the tertiary air inlet (11) composed of numerous holes distributed circularly around the outlet (8) and an independent blowing circuit (15) ends in longitudinal tubes (16, 17) arranged at the part low and at the inlet of the fore-hearth (4) and the hearth tube (1), which allows good regular combustion of the pulverized coal to be obtained.
