摘要:
The refuse-conveying device (2) described has a feed chute (4) connected to one end of a pipe (8). Running along the longitudinal axis of the pipe (8) is a screw conveyor (14) driven by a motor (20). The pipe (8) opens out into a pyrolysis reactor (10), in particular a carbonization drum operated as part of a low-temperature carbonization process. In order to enable refuse to be fed into the reactor while the reactor remains well sealed, the invention proposes that at least one supply line (32) which leads into the reactor (10) from outside is fitted in the space (30) between the wall (8a) of the pipe (8) and the reactor (10).

摘要:
Von eisenhaltigen Stoffen befreites Material wird in eine Grobfraktion und eine Feinfraktion getrennt und die Feinfraktion in die Primärkammer (2) eines Oberflächenschmelzofens (1) eingeleitet. Im Oberflächenschmelzofen (1) wird eine Luftzahl von λ = 0,7 bis λ = 1,3 eingestellt. Das geschmolzene Material verläßt die Primärkammer (2) zusammen mit dem Rauchgas. Das geschmolzene Material wird durch die Sekundärkammer (5) geleitet und als Schlacke ausgetragen.
摘要:
Ofenaggregat aus einem Ofen (1), einem Abhitzekessel (2) und einem zwischen Ofen (1) und Abhitzekessel (2) angeordnetem Schließring (3). Der Ofen (1) weist eine Abgasaustrittsöffnung (5) mit über den Umfang der Abgasaustrittsöffnung (5) umlaufendem Ofenflansch (6) auf. Der Abhitzekessel (2) weist eine Abgaseintrittsöffnung (7) mit über den Umfang der Abgaseintrittsöffnung (7) umlaufender Öffnungswand (8) auf. Der Schließring (3) ist an der Öffnungswand (8) verschiebbar und mit einem Dichtabschnitt (10) gegen den Ofenflansch (6) mit der Maßgabe andrückbar, dass ein zwischen Ofenflansch (6) und Öffnungswand (8) vorhandener Spalt (4) abgedichtet wird. An den Dichtabschnitt (10) schließt ein Innenabschnitt (11) des Schließringes (3) an und dieser Innenabschnitt (11) ragt in die Abgaseintrittsöffnung (7) hinein.
摘要:
Described is a method of reducing all emissions produced when waste is incinerated, the method calling for part of the fumes produced in the incinerator to be recycled, pure oxygen to be mixed with the fumes and the mixture to be burnt in the absence of air. A loop is thus set up in which the fumes are continuously enriched with oxygen, the loop being fitted with the first stage of a fume-purification installation in order to avoid the emissions becoming more concentrated. The ratio of fumes to oxygen in the synthetic air formed for combustion is between 4:1 and 1:1, preferably between 2:1 and 1.5:1.

摘要:
An apparatus for processing material such as organically coated waste and organic materials including biomass, industrial waste, municipal solid waste and sludge, is provided. The apparatus comprises a rotatable and tiltable furnace (1 ) having a body portion (15), a single material entry point (11) and a tapered portion (13) between said entry point and said body portion of the furnace. The furnace further includes means (25) for rotating the furnace (1) about its longitudinal axis and means (32, 102) for tilting the furnace. The furnace has a closure movable between an open position in which material can be introduced to the furnace (1) and a closed position in which the interior of the furnace is isolated from the external environment. A means at or adjacent said entry point (11) for directs gases in a direction inwardly of said furnace so as to provide a barrier of gas adjacent said opening to inhibit the entrance of oxygen containing atmospheric gas when said closure is in its open position.
