Embodiment Construction

[0043] The following description refers to advanced thermal treatment (ATT) of feedstock. Specific examples of ATT include pyrolysis and gasification. In this application, unless otherwise stated, pyrolysis and gasification shall have the same meaning. Furthermore, it should be understood that the description of an ATT plant may equally refer to a gasification plant or a pyrolysis plant. Similarly, a description of an ATT method or process may equally refer to a gasification method or process, or a pyrolysis method or process.

[0044] The present invention generally relates to the use of a helical or helical gas path within a heating envelope (gas envelope) to pyrolyze or gasify a gas mixture along this gas path. For the purposes of this document, the terms "helix" and "helical" are used to denote a helix or helix, unless otherwise stated. The heating envelope can be a heated pipe, pipe or ductwork, or a heated cone.

[0045] The heating envelope (gas envelope) 17 compris...

Abstract

The invention discloses a pyrolysis or gasification apparatus and a method. The pyrolysis apparatus has a heating system adapted to heat a first gas enclosure, wherein a gas path within the heated enclosure is helical or spherical. Pyrolysis is used to destroy oils, tars and / or PAHs in a gaseous mixture.

Description

technical field [0001] The present invention generally relates to pyrolysis and gasification methods and apparatus. Pyrolysis is used to destroy hot waste and / or generate gases therefrom. The destruction of thermal waste is a necessity in the hope of avoiding environmental damage due to burial in landfills or dumping at sea. However, some forms of destruction create gaseous pollution and / or carbon dioxide, causing environmental damage and potentially increasing global warming. Therefore, additional processing is required before using the gas. Background technique [0002] Advanced Thermal Treatment (ATT) mainly involves techniques using pyrolysis or gasification. ATT was discussed in a briefing paper entitled 'Advanced Thermal Treatment of Municipal Solid Waste' produced by the UK Government's Department for Environment, Food and Rural Affairs (DEFRA) (https: / / www.gov.uk / government / publications / advanced- thermal-treatment-of-municipal-solid-waste). The brief stated that...
