Abstract

L'invention porte sur un incinérateur, dans lequel le rendement de combustion est élevé, et la quantité de suie et de cendre produite par une combustion incomplète est extrêmement réduite. Un corps de fourneau (2) ayant une section (3) pour charger une matière incinérée comporte un tube de combustion de gaz d'échappement (5) ayant une partie située au moins dans le corps de fourneau (2), et un tuyau d'évacuation (6) ayant un dispositif d'alimentation en mélange gazeux (7) dans le trajet est couplé au tube de combustion de gaz d'échappement (5). Le dispositif d'alimentation en mélange gazeux (7) produit un mélange gazeux par mélange de gaz d'échappement et d'air frais, et délivre le mélange gazeux au corps de fourneau (2).
