Abstract
Description
Wie das Hauptpatent betrifft die Erfindung die Erstellung eines Schmelzvergasers sowie die Verwendung von Luft als Vergasungsmittel.Like the main patent, the invention relates to the creation a melting gasifier and the use of air as Gasifying agent.
Die Funktion eines Hochofens ist jedem Fachmann bekannt, so daß sie nicht mehr näher beschrieben werden muß. Es wer den in absehbarer Zeit viele Hochöfen stillgelegt werden müssen, da eine hohe Überkapazität vorhanden ist. Die Um rüstung dieser Aggregate und ihre Weiterverwendung als Schmelzvergaser zur Vergasung von brikettiertem Hausmüll, hausmüllähnlichen Abfällen, Sondermüll und/oder landwirt schaftlichen Rohstoffen wie Holz, Strohs, etc., wie unter P 36 42 102.0 beschrieben, könnte einen weltweiten Not stand bei der Entsorgung beheben, durch folgende Verfahrens schritte: Umkehrung des Gasstroms im Hochofen durch Herstel lung von Öffnungen im Ofenmantel in zwei verschiedenen Höhen: der unteren Schmelzzone (etwa in Höhe des Kohlensacks) sowie der oberen Hälfte des Schachtes und Einbau von neuen Wind formen mit Düsenstock und Blasformen (gekühlt oder ungekühlt) und einer dazugehörigen Ringleitung. Umstellung der alten Windformen zu Gasabzügen und ggf. Anschluß der Ableitung der Ringleitungen an die/den Winderhitzer und Verschließen der oberen Dichtgasleitungen des Hochofens. The function of a blast furnace is known to every specialist, so that it no longer needs to be described. It who many blast furnaces will be shut down in the foreseeable future because there is a high overcapacity. The order armor of these units and their further use as Melting gasifier for the gasification of briquetted household waste, household-like waste, hazardous waste and / or farmer commodities such as wood, straw, etc., such as under P 36 42 102.0 could be a global need corrected during disposal by the following procedure Steps: reversal of the gas flow in the blast furnace by manufacturers Openings in the furnace jacket at two different heights: the lower melting zone (approximately at the level of the coal sack) and the top half of the shaft and installation of new wind molding with a nozzle block and blow molds (cooled or uncooled) and an associated ring line. Conversion of the old Wind forms for gas fume cupboards and, if necessary, connecting the derivation of the Ring lines to the hot water heater and closing the upper sealing gas lines of the blast furnace.
Es wurde gefunden, daß auf diese einfache Weise, ein be stehender Hochofen zu einem Schmelzvergaser umgerüstet werden kann. Am wichtigsten ist dabei, daß fast die ge samte Infrastruktur des Hochofens Verwendung findet. Auch die Art des Gases, welches erzeugt werden soll, ist steuer bar, denn es wird nicht immer teueres Synthesegas (CO + H2) gebraucht, das ja nur mit reinem Sauerstoff erzeugt werden kann. Für die Verbrennung z. B. im Kraftwerk ist auch ein Schwachgas ausreichend, das mit Luft erzeugt werden und die ggf. mit Sauerstoff angereichert sein kann und im bestehenden Winderhitzer des Hochofens erhitzt wird, wobei der Winderhitzer die fühlbare Wärme des erzeugten Brenn- oder Synthesegases aus dem umgerüsteten Hochofen, welches ja stark überhitzt ist, aufgeheizt wird.It has been found that an existing blast furnace can be converted to a melter gasifier in this simple manner. The most important thing is that almost the entire infrastructure of the blast furnace is used. The type of gas that is to be generated is also taxable, because expensive synthesis gas (CO + H 2 ) is not always used, which can only be generated with pure oxygen. For the combustion z. B. in the power plant, a lean gas is also sufficient, which can be generated with air and which may be enriched with oxygen and is heated in the existing blast heater of the blast furnace, the blast heater heating the sensible heat of the combustion or synthesis gas generated from the converted blast furnace, which is very overheated, is heated up.
