Abstract

Le problème à résoudre par la présente invention est d'incinérer un article à incinérer à une température élevée avec une structure simple de façon à générer un gaz d'échappement clair avec moins de cendres d'incinération et de substances nocives générées. La solution selon l'invention porte sur un incinérateur qui est configuré de telle sorte qu'une chambre de combustion secondaire 2 est disposée au-dessous d'une chambre de combustion primaire 1 dans laquelle une grille 7 est disposée, un gaz de combustion s'écoule de la chambre de combustion primaire 1 dans la chambre de combustion secondaire 2 située au-dessous, la chambre de combustion primaire 1 coupe l'air, l'article à incinérer est amené sur la grille 7, la grille 7 est pourvue d'une pluralité de plaques à plusieurs étages 9 stratifiées en plusieurs étages par l'intermédiaire d'un espace de soufflage d'air 11, les plaques à plusieurs étages 9 sont des plaques inclinées à plusieurs étages 10 qui s'inclinent vers le bas vers l'extérieur sur les deux côtés d'un bord supérieur 16, une plaque inclinée d'étage inférieur 10B fait saillie d'un étage supérieur vers l'extérieur, et une soufflante 8 qui souffle de l'air de force dans la grille 7, et souffle de l'air à travers l'espace de soufflage d'air 11 vers l'extérieur, ce qui permet d'incinérer l'article à incinérer.
