Definitions
- the waste material may be domestic, industrial or natural waste material, or combinations of such material.
- the waste material may be domestic and/or industrial waste material.
- the majority of the known types of apparatus operate such that they generate gas which is then fed to burners in order to heat a pyrolysis chamber forming part of the apparatus. This generation of gas and the subsequent feeding the gas to the burners is inefficient and environmentally unfriendly. More specifically, the pyrolysis chamber is heated from the outside in the manner of heating a boiler, with most of the heat generated passing up through a chimney. The heat generated which passes up the chimney may be 70% of the overall heat generated. Thus large amounts of gas are wasted, with equally large amounts of heat being discharged to the atmosphere.
- apparatus for the pyrolysis of waste material which apparatus comprises a pyrolysis chamber which is heated by electrical heating means located within the pyrolysis chamber and in a floor part of the pyrolysis chamber.
- the apparatus of the present invention is advantageous in that less power is required to heat the pyrolysis chamber than in the above mentioned known apparatus. This is because, in the apparatus of the present invention, all heat that is generated by the electrical heating means is able to be generated and used exactly where it is required in the pyrolysis chamber. An exhaust chimney is not needed and thus the apparatus is more environmentally friendly than the above mentioned known apparatus because the apparatus of the present invention does not need to discharge large amounts of heat into the atmosphere.
- the use of the electrical heating means enables the apparatus of the present invention to be left in a standby mode when it is not in use. This overcomes a well known problem of condensation which occurs in the known apparatus and often causes failure of chamber walls in the known apparatus.
- the apparatus of the present invention is one in which the pyrolysis chamber is an outer shell which is made of a metal and which has a heat insulating lining.
- the metal is preferably steel but other metals may be used if desired. Any suitable and appropriate heat insulating lining may be employed. Different parts of the pyrolysis chamber can have the same or different types of heat insulating material.
- the apparatus of the present invention is one in which the floor part of the pyrolysis chamber is formed by a floor of the outer shell and the heat insulating lining on the floor of the outer shell, and in which the electrical heating means is suspended within the heat insulating lining on the floor part of the pyrolysis chamber and such as not to contact the outer shell of the pyrolysis chamber, thereby to ensure that the outer shell of the pyrolysis chamber does not become electrically conducting.
- the heating means may advantageously be suspended on mounting blocks.
- the heat insulating lining on the floor of the pyrolysis chamber may be formed of fire bricks. Other types of material may be used if desired.
- the electrical heating means comprises electrical heating elements wound on ceramic tubes.
- the ceramic tubes are able to provide support and insulation for the electrical heating elements.
- the ceramic tubes are also able to provide a means of supporting the electrical heating means, for example on the mounting blocks.
- the electrical heating means may be a plurality of separate heaters. Each separate heater may form a large high power source of heat, for example with an output of 10Kw.
- the apparatus may be one in which an electrical supply for the electrical heating means is through fittings constructed to protect the electrical supply from contact with the outside of the pyrolysis chamber, and also constructed to maintain an airtight seal with the pyrolysis chamber.
- the pyrolysis chamber is preferably constructed as a large long horizontally-extending chamber. Other shapes for the pyrolysis chamber may however be employed. Where the pyrolysis chamber is the large long horizontally-extending chamber, then it will usually have a door at each end. The doors are advantageously constructed to be heavy.
- the apparatus of the present invention may include a hearth which is positioned over the electrical heating means, which is composed of a plurality of ceramic plates, and over which the waste material passes during use of the apparatus.
- the apparatus may include an external temperature controller and a thermal coupler, whereby the internal temperature of the pyrolysis chamber is able to be controlled over a wide temperature range.
- the apparatus may include means for moving the waste material over the floor part of the pyrolysis chamber.
- the means for moving the waste material may be a rake system.
- the rake system may include a crank mounted internally with arms which move.

- the pyrolysis chamber 2 is heated by electrical heating means 4 located within the pyrolysis chamber 2 and in a floor part 6 of the pyrolysis chamber 2,
- the pyrolysis chamber 2 comprises an outer shell 8 which is made from steel and which has a heat insulating lining 10. Positioned between the outer shell 8, the heat insulating lining 10, is a secondary heat insulating lining 12.
- the floor part 6 of the pyrolysis chamber 2 is formed by a floor 14 of the outer shell 8, the heat insulating lining 10, and the secondary heat insulating lining 12 on the floor 14.
- the electrical heating means 4 is suspended within the heat insulating lining 10 on the floor part 6 of the pyrolysis chamber 2 as shown in Figure 1.
- the suspension of the electrical heating means 4 is such that the electrical heating means 4 does not contact the outer shell 8, thereby to ensure that the outer shell 8 does not become electrically conducting during use of the pyrolysis apparatus.
- the electrical heating means is suspended on mounting blocks.
- the heat insulating lining 10 is formed of firebricks. Other suitable and appropriate materials may be used if desired.
- Electrical heating means comprises electrical heating elements wound on ceramic tubes.

- the fittings are also constructed to maintain an airtight seal with the outer shell 8 of the pyrolysis chamber 2.
- the pyrolysis chamber 2 is preferably constructed as a large long horizontally-extending chamber. This chamber has a heavy door at each end. The doors enable waste material to be introduced into the pyrolysis chamber 2, and removed from the pyrolysis chamber 2.
- the pyrolysis chamber 2 includes a hearth 16 which is positioned over the electrical heating means 4.
- the hearth 16 is composed of a plurality of ceramic plates 18. A stream of the waste material passes over the hearth 16 during use of the apparatus of the invention.
- the apparatus of the invention includes an external temperature controller (not shown) and a thermal coupler (not shown).
- the temperature controller and the thermal coupler enable the internal temperature of the pyrolysis chamber 2 to be able to be controlled over a wide temperature range.
- the apparatus also includes means for moving the waste over the floor part 6 of the pyrolysis chamber 2.
- the means for moving the waste is preferably a rake system (not shown).
