Kontaktmassen.Contact masses.
Patentiert im Deutschen Reiche vom 9. Juli 1911 ab.Patented in the German Empire on July 9, 1911.
Es ist bekannt, das Eisenkontaktverfahren in kontinuierlich auf indirektem Wege beheizten Retorten auszuführen.It is known that the iron contact process is heated continuously in an indirect way To run retorts.
Ebenso ist die Wasserstoffbereitung in Generatorschächten, welche durch direkte periodische Beheizung betrieben werden, bekannt. Likewise, the hydrogen preparation in generator shafts, which by direct periodic Heating operated, known.
Gemäß vorliegender Erfindung erfolgt die Wasserstoffbereitung derart, daß der Kontaktmasse durch periodische Beheizung einerseits und Wärmespeicher andererseits kontinuierlich Wärme zugeführt wird. Zu diesem Zwecke sind die Zersetzer so angeordnet, daß sie mit als Überhitzer ausgebildeten Heizräumen in unmittelbarem Wärmeaustausch stehen. Hierdurch ist es ermöglicht, dem Zersetzer durch periodische Beheizung des Ofens kontinuierlich Wärme zuzuführen, denn in der Schamottewand des Ofens und dem in dem Heizraum angeordneten feuerfesten Gitterwerk wird eine so bedeutende Wärmemenge aufgespeichert, daß während des Aussetzens der Beheizung durch Wärmestrahlung und Wärmeleitung ein unerwünschter Temperaturabfall im Zersetzer vermieden wird, was von großer Wichtigkeit ist und ausgleichend bei den einzelnen Perioden des Prozesses wirkt.According to the present invention, the hydrogen preparation takes place in such a way that the contact mass through periodic heating on the one hand and heat storage on the other hand continuously Heat is supplied. For this purpose, the decomposers are arranged so that they with Boiler rooms designed as superheaters are in direct heat exchange. Through this it is possible to continuously heat the decomposer by periodically heating the furnace To add heat, because in the fireclay wall of the furnace and the refractory latticework arranged in the boiler room is a so significant amount of heat accumulated that during the interruption of the heating an undesirable temperature drop in the decomposer due to thermal radiation and heat conduction is avoided, which is of great importance and balancing the individual periods of the process works.
Zur Ausführung des Verfahrens kann man beispielsweise einen Ofen benutzen, bei welchem ein als Reaktionsraum dienender Zylinder zentral durch einen mit Gitterwerk ausgerüsteten Schacht gelegt ist. Dieser Ofen wird beispielsweise derart betrieben, daß Reduktionsphasen und Oxydationsphasen miteinander abwechseln, während Heizphasen je nach Bedarf eingelegt werden.To carry out the method, for example, an oven can be used in which a cylinder serving as a reaction space centrally through a cylinder equipped with latticework Shaft is laid. This furnace is operated, for example, in such a way that reduction phases and oxidation phases alternate with one another, while heating phases are inserted as required.
Im Gegensatz zu den bekannten periodisch (direkt) beheizten Schachtöfen wird im vorliegenden Falle die direkte Beheizung und damit die schnelle Verschmutzung, die beim Schachtofen fast unvermeidlichen örtlichen Uberhitzungen und die ungleichmäßige Erhitzung der Kontaktmasse vermieden. Während man einen mit Eisenfüllung versehenen Generatorschacht nur nach beendigter Oxydation in einer besonders eingelegten Phase beheizen kann, während eine Beheizung während oder zwischen den anderen Phasen unmöglich ist, kann hier die Beheizung unabhängig vom Zustand der Eisenfüllung erfolgen. Wenn der Zersetzer mit dem Überhitzer in direkter Verbindung steht, so kann der letztere noch vorteilhaft zur Verbrennung der Abgase der Reduktion benutzt werden, so daß in diesem Falle also die Reduktiosphase mit der Heizphase zusammenfallen würde. Ebenso kann derselbe zur Überhitzung des Gases bzw. Dampfes benutzt werden.In contrast to the known periodically (directly) heated shaft furnaces, in the present Fall in the direct heating and with it the rapid pollution, which is almost unavoidable with the shaft furnace local Overheating and the uneven heating of the contact mass avoided. While a generator shaft filled with iron can only be installed after the oxidation has ended can heat in a specially inserted phase while heating during or between the other phases is impossible, the heating can be independent here on the condition of the iron filling. If the decomposer with the superheater is in direct connection, the latter can still be advantageous for the combustion of the Waste gases from the reduction are used, so that in this case the reduction phase would coincide with the heating phase. It can also overheat the Gas or steam can be used.
Gegenüber dem Retortenverfahren mit kontinuierlicher Beheizung bietet vorliegendesCompared to the retort process with continuous heating, the present
Verfahren den Vorteil, daß an Heizmaterial gespart wird und daß Uberhitzungen vermieden werden.The method has the advantage that heating material is saved and that overheating is avoided will.
