Abstract

L'invention concerne un incinérateur qui comporte une grille (10) et un poteau de support (30) situé des deux côtés de la grille (10). Des entretoises (20) montées fixement dans les deux côtés de la grille (10) et déplaçables vers l'extérieur en fonction de la dilatation thermique de la grille (10), ainsi que des éléments de support horizontaux (40) fixés sur le poteau de support (30), sont également inclus. Les entretoises (20) sont placées sur les éléments de support horizontaux (40). Lors de la combustion de déchets dans l'incinérateur, la grille (10) se dilate sous l'effet de la chaleur, et les entretoises (20) fixées dans la grille (10) sont amenées à se déplacer sur les éléments de support horizontaux (40), afin que les contraintes thermiques puissent être libérées, et que la stabilité interne du poteau de support en structure d'acier puisse être efficacement assurée.
