A gasification auger with a hopper reservoir (1) that feeds a variety of undried, friable materials to an auger (2) powered by a motor (3). Along the auger (2) there is a section where the helix is interrupted by a series of blades (5). Surrounding the output end of the auger tube (4) is a cylindrical combustion chamber (10,11), which generates heat to gasify the raw material whilst it is completely contained within the auger tube (4). The combustion chamber (10,11) has air direction tubes, between the inner combustion chamber (11) and the outer combustion chamber (10). Air and fuel is introduced to the combustion chamber (10,11) and the resulting heated gas is then extracted and can be used to run a variety of engines or equipment before being directed to a heating chamber (7) which may form part of an integral heat exchanger. The auger tube (4) is provided with apertures for the removal of gases (9), which can be fed to a burner (12) in the combustion chamber. Another aperture (6) allows for the extraction of steam from damp material.

The inner compartment (13) of a low-temperature carbonisation drum (8) for waste (A) which can be rotated about its longitudinal axis (10) contains a plurality of heating pipes (12) one end of which is secured to a first end plate (28) and the other to a second end plate (30). Between the two end plates (28, 30) there is at least one supporting point (X, Y) for the heating pipes (12) in order to prevent sag. Here, each supporting point (X, Y) is divided into p » 2 spaced partial supports, each with a console arrangement (I, II, III). Each console arrangement (e.g. I) comprises several supporting brackets (e.g. Ia to Id) in the same plane. The supporting brackets (Ia to Id, IIa to IId, IIIa to IIId) are staggered one behind another and in rotation. Thus the solid components (f) of the waste (A) can be conveyed past the supporting points (X, Y) largely without any hindrance.
摘要:
A gravity-fed housing for use in a gasification system is disclosed. The gravity-fed housing has a receiving end panel that forms a receive opening in a first plane. The receive opening is configured to receive a first plurality of heat carriers via gravity. The gravity-fed housing includes a siding connected to the receiving end panel. The siding forms a chamber and a discharge opening in a second plane that is parallel to the first plane. The discharge opening is offset with respect to the receive opening such that a line perpendicular to the receiving end panel that extends through a center point of the receive opening does not intersect a center point of the second opening. The siding includes a first panel that comprises a guiding surface that intersects the line and is angled toward the discharge opening.
摘要:
A heating chamber for solids which can rotate about its longitudinal axis (10), especially a low-temperature carbonisation drum (8) for waste (A), is fitted with a plurality of largely mutually parallel heating pipes (12) installed inside it. In order to ensure that only finely divided matter can collect between the heating pipes (12b) and the inner wall (33) of the heating chamber, according to the invention the heating pipes (12) viewed in cross section are arranged in a virtually closed row along the wall (33) of the inner chamber (13). In this row, which may be circular, there are blind tubes (12D) which are preferably easy to remove and, in particular, have the same diameter as the heating pipes (12b).

The invention relates to a cracking furnace (1) containing a tubular vertical chamber (2) which comprises an inlet (4) for introducing a gas to be treated and an outlet (5) for removing said gas from the chamber, means for heating said gas which comprise a heating tube (9) extending vertically inside the chamber and coaxial with the chamber, the heating tube being shaped in such a way as to have a closed lower end and being arranged in such a way that the lower end thereof is arranged in the chamber and such that the upper end thereof is connected to a burner (13) of the heating means arranged outside the chamber. The invention also relates to an assembly comprising such a cracking furnace and a device for thermal treatment of biomass and/or waste, an outlet of which is connected to the inlet of said cracking furnace.
