Abstract: A method and apparatus are described for utilizing fuels, residues and waste by gasification in a free-flowing stream under normal or increased pressure at temperatures higher than 900° C., preferably between 1100 and 1600° C., with a gasifying medium containing free oxygen, in which the fuels, residues and waste are completely vaporized by the direct or indirect supply of heat and then fed in vapor form to a gasification reactor.

Abstract: The invention relates to a reactor vessel and method for the gasification of carbon-containing fuel, residual and waste materials using an oxygen-containing oxidizing agent and in a reaction chamber which is designed as an entrained-bed reactor, at pressures between ambient pressure and 80 bar, preferably between ambient pressure and 30 bar, the contour of the reaction chamber being delimited by a cooling system, and the pressure in the cooling system always being held at a higher level than the pressure in the reaction chamber, and the cooling system withstanding the maximum possible pressure difference with respect to the reaction chamber, which has been depressurized to atmospheric pressure, which reactor vessel is distinguished by the fact that cooling channels are formed by webs which are in contact both with a refractory protective layer and with the pressure shell.

Abstract: A reactor for the gasification of carbon-containing fuels, residues and waste by an oxygen-containing oxidizing agent in a reaction space designed as a fly stream reactor, at pressures of between ambient pressure and 80 bar, preferably between ambient pressure and 30 bar, the reaction space contour being delimited by a refractory lining within a pressure casing, wherein the temperature of the pressure casing can be regulated, the pressure casing having cooling ducts affixed to an outer surface thereof.

Abstract: A method for gasification of halogen containing remainders and waste materials is provided including obtaining a reactant including halogen containing remainders and/or halogen containing waste, and where necessary an additional combustible. The reactant has a heat value of greater than 6 MJ/kg and is reacted with a gasification agent containing free oxygen into a crude gas using a flame reaction at a pressure in excess of ambient pressure to a final temperature of at least 1100° C. The crude gas contains carbon monoxide, hydrogen-containing gas and/or halogen/hydrogen containing gas. The crude gas can then be cooled and further processed.

Abstract: An apparatus for sealing a rotary tube drum of a furnace to another furnace component. Two concentric resilient metal ring segments are provided on a disk to comprise the sealing elements of the present invention. A plurality of springs arranged as a ring apply pressure to the disk and ring segments to ensure a consistent and self-adjusting seal between the joined components. Links located circumferentially about the disk limit lateral movement, yet allow axial movement, of the seal. It is thereby possible, according to the present invention, to provide a resilient seal between a rotary tube and another component of a furnace that yields a self-adjusting gas-impermeable seal between the mating components.

Abstract: A device for utilizing combustion, residual and waste materials containing carbon and ash by gasification with an oxygen-containing oxidizing agent at temperatures above the melting point of the inorganic parts in a reaction chamber and at a pressure between ambient pressure and 60 bar. The reaction chamber contour is formed in part by a refractory-grade lining and in part by a cooling system comprising cooling coils connected in a gas-tight manner. The coils are coated with a thin layer of a ceramic mass that conducts heat well on a side facing the reaction chamber. The cooling coils are operated, while being cooled by pressurized water, below or above the boiling point of the cooling water.
