Definitions
- Thermal oxidiser 1 in accordance with an embodiment of the present invention which is intended to convert all species in the feed liquid (W) and feed gas (G) to their most oxidised state.
- Thermal oxidiser 1 comprises an elongated retort 3 provided with a combustion gas input lance 5, a feed liquid input lance 7, a salt tray 9, one or more flow straighteners 11 and an exhaust gas outlet 13.
- Retort 3 comprises an elongated cylindrical high temperature, corrosion-resistant wall 15 with a first end plate 17 sealably fastened to a first end 19 and a second end plate 21 sealably fastened to the second, opposite end 23 of the wall.
- retort 3 is arranged with its longitudinal axis substantially horizontal and the interior of retort 3 is nominally divided into six zones in the following order, starting from the first end 19:
- Unstraightened flow through the retort would normally be substantially laminar in the Residence Zone.
- the flow straighteners provide sufficient pressure drop and mixing to break up the parabolic laminar flow profile.
- a laminar flow profile would halve the residence time for the centreline as the centreline velocity is twice that of the average. Therefore, the effectiveness of the residence zone is improved by using flow straighteners.
- the feed liquid input lance is preferably designed to deliver the feed liquid into the salt tray while minimising the vaporisation of volatile compounds in the feed liquid while in the lance.
- the lance is preferably liquid cooled.
- the feed liquid input lance is mounted in the vertical orientation to help prevent sagging over time in the high temperature environment.
- An insulated cover on the feed liquid input lance is preferably provided. The insulation cover has two purposes:
