Abstract

Selon un procédé de régulation de combustion d'un incinérateur de déchets à distributeur automatique, de l'air de combustion primaire (A) est soufflé dans une chambre de combustion à partir d'une zone sous-jacente à un distributeur automatique, un gaz à température élevée (B) étant soufflé dans une zone souhaitée entre une zone de début de combustion et une zone de combustion principale. Un gaz d'échappement de circulation (C) comprenant, comme constituant, au moins un gaz d'échappement évacué à partir de l'incinérateur est soufflé vers une partie surjacente à une position d'admission pour le gaz à température élevée (B) ou vers le côté aval d'un sens d'écoulement de gaz. Un gaz d'agitation (D) d'air, le gaz d'échappement ou un gaz mixte d'air et du gaz d'échappement de circulation est soufflé vers une zone de combustion secondaire.
