Abstract

La combustion de combustibles solides à basse température de fusion des cendres produit du mâchefer (28) qui enveloppe des parties du combustible, empêche une combustion complète, et obstrue l'alimentation en air, ce qui aboutit à une interruption du processus de combustion. Selon l'invention, la braise et les cendres en fusion sont remuées au moyen d'un peigne de nettoyage (22) et évacuées du brûleur. Le brûleur est composé de barreaux de grille (25) rotatifs agencés parallèlement les uns aux autres dans les parois intérieures (1). Le peigne de nettoyage (22) se déplace entre les barreaux de grille (25), vers le haut entre les barreaux de grille (25), en direction de l'ouverture du brûleur, vers le bas sous les barreaux de grille, et enfin dans la direction du flasque (7) du brûleur. Lorsque le mâchefer (28) adhère sur les barreaux de grille (25), il est éliminé par frottement par le peigne de nettoyage (22). Le combustible chargé dans la trémie (8) glisse vers le bas sous l'effet de la gravité, ouvre l'abattant (9) de la trémie, et est poussé sur les barreaux de grille (25) par le piston (11). Le piston (11) présente au moins une ouverture (15) pour l'air secondaire (5) qui sert également à son refroidissement. La cendre tombée sous les barreaux de grille (25) est soufflée par le ventilateur (13) à travers une découpe dans le fond de brûleur (30) ouverte par le tiroir de fond (20).
