Abstract
A furnace for waste material. The furnace has a central chute for receiving he waste material, and a combustion chamber which is arranged below the chute and has a closed bottom. The transition between the central chute and the combustion chamber is designed as a constriction in such a way that the waste material remains above the constriction in the central chute for drying and degasification up to the point of combustion. Essentially, only ashes pass through the constriction downwardly into the combustion chamber. The gases which are withdrawn downwardly out of the chute are also guided through the constriction into the combustion chamber. Fresh air supply lines discharge at the constriction and in the lower portion of the chute above the constriction. The flue gases formed in the combustion chamber are guided to a flue through discharge openings in the exhaust chamber of the combustion chamber. The exhaust chamber is designed in such a way that it surrounds the central chute. A device is provided in the chute for stirring the waste material. A guide arrangement is provided below the transition area between the central chute and the combustion chamber. Starting from this transition area, the guide arrangement is formed as an intermediate wall in such a way that the combustion chamber is divided into an inwardly lying step-down flow portion, and an outwardly lying chamber which at the same time forms the lower portion of the exhaust chamber. Further fresh air supply lines discharge in the region of the lower portion of the exhaust chamber.
