Abstract
A shredding and feeding system for an incinerator, wherein a shredding chamber is isolated from atmosphere by means of an airlock through which material to be incinerated passes into the shredding chamber. The oxygen content of the shredding chamber is maintained below a predetermined level to minimize risk of explosions and premature incineration of material.
Claims22
An apparatus for burning a combustible material, comprising:
- a kiln;
- an airlock chamber;
- and
- shredding and conveying apparatus for shredding and conveying combustible material and having an enclosure means operatively coupled between said kiln and said airlock chamber, said apparatus further comprising a means for relieving internal pressure in fluid communication with said enclosure means, said pressure relief means preventing escape of gases from the enclosure means at predetermined operating pressures;
- and
- means for controlling the oxygen content of said enclosure means whereby combustible material is shredded and conveyed into said kiln in an atmosphere whose oxygen content is maintained below a preselected level.
3 more elements
An apparatus for incinerating material, comprising:
- a kiln;
- an enclosed apparatus for shredding and conveying material into said kiln having an outlet operatively coupled to said kiln, said apparatus comprising a means for relieving internal pressure, when said pressure exceeds a pre-determined operating pressure;
- and
- an airlock chamber having an inlet and an outlet operatively coupled to an inlet of said apparatus for shredding and conveying, through which material to be shredded is introduced into said apparatus for shredding and conveying said airlock chamber serving to isolate said apparatus for shredding and conveying from atmosphere.
