Abstract
A pyrolysis surface such as a rotating retort is provided by copper sheet supported by a nickel alloy framework. Pyrolysis is used to destroy calorific waste and/or to produce gas therefrom.
Claims19
A pyrolysis apparatus comprising an outer retort structure constructed at least partially of a sheet of a high thermal conductivity metal directly affixed, at a first side of the sheet of the high thermal conductivity metal, to a framework of a high temperature strength metal, the framework of high temperature strength metal having openings there through;
- and wherein the first side of the sheet of the high thermal conductivity metal is exposed through the openings, wherein the sheet of the high thermal conductivity metal is explosively welded to the framework of the high temperature strength metal.
A gasifier comprising an outer retort pyrolysis structure at least partially constructed of a sheet of high thermal conductivity metal directly affixed, at a first side of the sheet of the high thermal conductivity metal, to a framework of high temperature strength material and enclosed within a thermally insulated housing, and a heating system capable of heating the structure to a temperature sufficient for pyrolysis of a calorific material, wherein the first side of the sheet of the high thermal conductivity metal is exposed to the heating system through openings of the framework of high temperature strength material, wherein the sheet of the high thermal conductivity metal is explosively welded to the framework of the high temperature strength metal.
A method of making an outer retort pyrolysis structure intended for gasifying feedstocks at high temperatures, comprising:
- providing a first sheet of a high thermal conductivity metal;
- providing a second sheet of a high temperature strength metal;
- explosively welding said first and second sheets together;
- and
- forming openings through the second sheet thereby exposing at least a portion of the first sheet of the high thermal conductivity metal through the openings formed in the second sheet.
