    • A solid fuel gasifier includes first wall structure (12) defining a gasification chamber (14) and means (50, 52) to collect particulate solid residue from gasification in the gasification chamber. Second wall structure (16) defines a gas combustion chamber (17) and means (19) is arranged for admitting a flow of hot gases from the gasification chamber to the gas combustion chamber as combustion takes place. Also provided is means (178, 170) to conduct hot gases from the gasification chamber and/or gas combustion chamber into thermal contact with said collected particulate solid residue, for facilitating post-combustion and/or post-reduction of the solid residue. Also disclosed are an agitator bed (52, 182) for fine particulate material, and a method of gasification of solid fuel.
    • 固体燃料气化器包括限定气化室(14)的第一壁结构(12)和用于从气化室中气化收集颗粒固体残余物的装置(50,52)。 第二壁结构(16)限定气体燃烧室(17),并且设置装置(19),用于在发生燃烧时将气体流从气化室引入气体燃烧室。 还提供了用于将来自气化室和/或气体燃烧室的热气体与所述收集的颗粒固体残余物热接触的装置(178,170),以便于固体残余物的后燃烧和/或后还原。 还公开了一种用于细颗粒材料的搅拌床(52,182)和固体燃料的气化方法。

    • A process and apparatus for gasification of organic materials (typically incorporated in domestic and industrial wastes, including auto shredder residues) to produce useful synthesis gas (with a major content CO and H.sub.2) with effectively non-toxic ash residue by means of at least one continuously operated burner, preferably stoichiometrically balanced (1:2 for natural gas/oxygen) at least at startup and shut down (optionally with some excess of oxygen, usually under steady-state conditions, such as at a ratio of 1:4 or higher, especially if the charge has well over 18% water content), directed into a primary single stage reaction zone (through an opening in common with the effluent product gas discharged therefrom such as to assure intimate contact therebetween), which zone contains a tumbling charge in a rotating barrel-shaped horizontal reactor thus heated to from about 650.degree. to about 800.degree. C. (below the incipient fusion temperature of the charge) and controlled to remain in such temperature range (by adjustment of the burner volume and fuel-to-oxygen ratio for any given charge) resulting in thermally cracking and gasifying the organic materials in the charge and reacting the complex hydrocarbons and gas evolved (1) normally with the CO.sub.2 and H.sub.2 O derived from burner combustion of a fuel and oxygen-containing gas at a high flame temperature, typically 2500.degree. to 3000.degree. C., (2) with excess oxygen, and/or (3) partially with H.sub.2 O or CO.sub.2 otherwise added to or, present in, the charge.
