Description
Verfahren zur direkten Herstellung von Zementen im Abstichgenerator. Die Betriebsweise der Abstichgeneratoren ist bekannt. Als Brennstoffe können sowohl hochwertige als auch minderwertige Materialien verwendet werden. Das erzeugte Gas hat einen Heizwert von etwa iooo WE/i cbm, die flüssig entfallende Schlacke entspricht ungefähr einer sauren Gießereischlacke. Zufolge seines geringen Heizwertes kommt das Gas für metallurgische Zwecke nicht in Frage.Process for the direct production of cements in the tapping generator. The mode of operation of the tapping generators is known. As fuels can be both high quality as well as inferior materials are used. The generated gas has a calorific value of around iooo WE / i cbm, which corresponds to liquid slag roughly an acid foundry slag. As a result of its low calorific value the gas for metallurgical purposes is out of the question.
Die im Abstichgenerator erzeugten Produkte, nämlich Gas und Schlacke, lassen sich nun dadurch ganz bedeutend veredeln, daß man den Generator anstatt mit gewöhnlicher Luft mit an Sauerstoff angereicherter Luft oder mit hochprozentigem Sauerstoff betreibt. Durch die hierdurch erzielbare höhere Temperatur ist es nämlich möglich, dir Schlacke eine solche Zusammensetzung zu geben, daß sie ohne weiteres als hochwertiger Zement entfällt. Je nach der Schlackenzusammensetzung lassen sich im allgemeinen zwei Zementarten herstellen, nämlich ein stark kalkhaltiger Portlandzement und ein sogenannter Tonerde-Schmelzzement.The products produced in the tapping generator, namely gas and slag, can now be refined quite significantly by using the generator instead of with Ordinary air with oxygen-enriched air or with high-percentage air Oxygen operates. Because of the higher temperature that can be achieved in this way, it is possible to give you slag such a composition that it easily as high-quality cement is not required. Depending on the slag composition, generally produce two types of cement, namely a highly calcareous portland cement and a so-called alumina fused cement.
Im Gegensatz zum seitherigen Betrieb der Abstichgeneratoren lassen sich auch sonst nicht verwendbare Brennstoffe vergasen, selbst backende Kohle macht keine Schwierigkeiten, da sie sich -infolge der für die Zementherstellung erforderlichen Zusätze wie eine Magerkohle verhält. Waschberge lassen sich mit ganz besonderem Vorteil auf Tonerde-Schmelz-Zement verarbeiten, wenn man -durch Zusatz von Eisen oder von Eisenerzen der Kieselsäure Gelegenheit gibt, als Ferrosilicium gebunden zu werden.In contrast to the previous operation of the tapping generators also gasify otherwise unusable fuels, make self-baking coal no difficulties as they are due to the requirements for cement production Additives behave like a lean coal. Wash mountains can be made with very special Advantage to work with alumina-fused cement, if -by adding iron or from iron ores the silica gives the opportunity to be bound as ferrosilicon to become.
Neben diesen hochwertigen Zementprodukten entstehen gleichzeitig hochwertige Brenngase, die sich vor allem durch einen viel geringeren Stickstoffgehalt auszeichnen. Beim Arbeiten mit einer Luft von 45 Prozent Sauerstoffgehalt bildet sich ein Gas von etwa 2200 WE /i cbm, das für die verschiedensten Zwecke sehr wertvoll ist. Verarbeitung bituminöser Brennstoffe auf diesem Wege hat außerdem noch den Vorteil, daß die aus dem Generator entweichenden Gase die gesamten Schwelprodukte in relativ konzentrierter Form mit sich führen, was deren nachfolgende Abscheidung sehr erleichtert und gewinnbringend macht. Durch die geringeren Gasmengen stellt sich auch die Temperatur an der Gicht niedriger ein als bei der seitherigen Betriebsweise, was der Erzielung wertvoller Generatorschwelprodukte sehr zustatten kommt.In addition to these high-quality cement products, high-quality products are also produced Fuel gases, which are mainly characterized by a much lower nitrogen content. When working with air with an oxygen content of 45 percent, a gas is formed of about 2200 WE / i cbm, which is very valuable for a wide variety of purposes. processing bituminous fuel in this way also has the advantage that the the gases escaping from the generator contain the entire carbonization products in relatively more concentrated form Carry shape with you, which makes their subsequent deposition much easier and profitable power. Due to the lower amount of gas, the temperature of the gout also adjusts itself lower than in the previous mode of operation, which is more valuable to achieve Generator smoldering products comes in very handy.
Durch Dampfzusatz läßt sich die Schweltemperatur und die Höhe der Schwelzone in einfacher Weise beeinflussen.By adding steam, the smoldering temperature and the level of Affect the smoldering zone in a simple way.
