Gas barrier

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 the entry point and the body. The furnace has a closure through which material can be introduced to the furnace (1) when open and in which the interior of the furnace is isolated from the external environment when closed. A director at or adjacent the entry point (11) directs gases inwardly of the furnace so as to provide a barrier of gas adjacent the opening to inhibit the entrance of oxygen containing atmospheric gas when the closure is in its open position.

1. An apparatus for processing organically coated waste, organic materials, biomass, industrial waste, municipal solid waste and sludge, comprising:
a rotatable and tiltable furnace having a body portion comprising an interior and a exterior, a single material entry point having a closure movable between an open position in which material can be introduced to the furnace and a closed position in which the interior of the furnace is isolated from the external environment; and a tapered portion between said entry point and said body portion of the furnace; means for rotating the furnace about its longitudinal axis; means for tilting the furnace; and at least one director at or adjacent said entry point configured to direct gases in a direction inwardly of said furnace such that a barrier of gas is provided adjacent said opening to inhibit the entrance of oxygen containing atmospheric gas, when said closure is in its open position.
