Abstract

Chaudière de combustion à impulsions comprenant un tube de combustion essentiellement vertical (1), une chambre de compensation (2) au niveau de son extrémité inférieure, une grille (7) dans la partie inférieure du tube de combustion, des dispositifs (12, 13, 14) d'alimentation de la grille (7) en combustible, des dispositifs (21, 25) d'alimentation en air de combustion, et une ou plusieurs surfaces d'échange thermique (23) servant à récupérer la chaleur produite par la chaudière. La chaudière comprend une chambre supérieure de compensation (1) au niveau de son extrémité supérieur, et un séparateur (15) monté en aval de cette chambre et destiné à séparer les particules non brûlées. Un raccord (16) de sortie de particules solides est relié par l'intermédiaire d'un conduit de retour (19) à la zone située au-dessus de la grille (7) du tube de combustion (1) afin de brûler les résidus non brûlés et de réduire ainsi les pertes.
