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.
Claims23
A pyrolysis apparatus comprising:
- a retort structure, the retort structure comprising a sheet of a high thermal conductivity metal affixed to a framework of a high temperature strength metal, wherein the high thermal conductivity metal comprises copper.
A method of making a pyrolysis structure intended for gasifying feedstocks at high temperatures, comprising:
- providing a first sheet of a high thermal conductivity metal, wherein the high thermal conductivity metal comprises copper;
- providing a second sheet of a high temperature strength metal;
- and
- explosively welding said first and second sheets together.
1 more element
The method of claim 22, further comprising milling away portions of said second sheet to leave said first sheet exposed.
The method of claim 23, in which said first and second sheets are cylindrical.
