Description

Überhitzer für Wasserdampf, Gase u. dgl. Die Überhitzung von Wasserdampf, Gasen u. dgl. kann in Rohren aus Eisen meistens nur bis etwa 4.5'o=' ausgeführt werden. Für die Überhitzung auf höhere Temperaturen ist man auf die Anwendung von sogenannten Cowper-Apparaten angewiesen, mit denen man aber in umständlicher Weise nur periodisch arbeiten kann. Um kontinuierlich arbeiten zu können, war man bisher auf die Verwendung feuerfester Retorten angewiesen, die von außen erhitzt und durch welche die zu überhitzenden Dämpfe oder Gase geschickt wurden. Die aus Schamotte bestehenden Retortenwände übertragen aber infolge der schlechten Wärmeleitung der Schamotte die Wärme nur zum Teil auf die Dämpfe oder Gase.Superheater for water vapor, gases and the like. The superheating of water vapor, Gases and the like can usually only run up to about 4.5'o = 'in pipes made of iron will. For overheating to higher temperatures one is on the application of so-called Cowper apparatus, but with which one can work in a cumbersome way can only work periodically. In order to be able to work continuously, one was previously relies on the use of refractory retorts, which are heated from the outside and through which vapors or gases to be superheated were sent. The chamotte ones existing retort walls but transferred due to the poor heat conduction of the Fireclay only partially absorbs the heat from the vapors or gases.

Es wurde nun gefunden, daß sich als Material für solche überhitzer Eisenoxyde vorzüglich eignen. Diese sind nicht nur feuerfest und dabei weit bessere Wärmeleiter als Schamotte und andere hochfeuerfeste Materialien, sie können auch im elektrischen Ofen geschmolzen und zu verhältnismäßig dünnwandigen Röhren usw. von großer Festigkeit vergossen werden. In solchen Überhitzern lassen sich mit Vorteil die verschiedensten nicht reduzierend wirkenden Gase und Dämpfe, wie Wasserdampf, Kohlensäure, schweflige Säure, Stickoxyde, Chlor, Brom, Luft, Sauerstoff, Quecksilberdampf usw., auf hohe Temperaturen bringen. Es ist lediglich Sorge zu tragen, daß die Heizgase nicht reduzierend wirken, was zweckmäßig durch einen geringen Sauerstoffüberscbuß erreicht wird. Beispiel. Durch einen Ü berhitzer, der aus innen und außen gerippten, durch Gießen des Schmelzflusses erzeugten Röhren aus Eisenoxyduloxyd besteht und der durch Verbrennen von Braunkohlenstaub geheizt wird, wird Wasserdampf geleitet und dadurch auf i zoo bis 130o° C überhitzt. Der so überhitzte Wasserdampf wird z. B. in einen geeigneten Generator geleitet, in dem man so kontinuierlich Wassergas ohne Zwischenschaltung von Aufheizperioden erzeugen kann.It has now been found that the material for such superheaters Iron oxides are eminently suitable. These are not only fireproof and at the same time far better Heat conductors as fireclay and other highly refractory materials, they can too melted in the electric furnace and turned into relatively thin-walled tubes, etc. be cast of great strength. Such superheaters can be used with advantage a wide variety of non-reducing gases and vapors, such as water vapor, Carbonic acid, sulphurous acid, nitrogen oxides, chlorine, bromine, air, oxygen, mercury vapor etc., bring to high temperatures. It is only necessary to ensure that the heating gases do not have a reducing effect, which is expedient by a slight excess of oxygen is achieved. Example. Thanks to an overheater, which consists of ribbed inside and outside, tubes produced by pouring the melt flow are made of ferric oxide and which is heated by burning lignite dust, water vapor is conducted and thus overheated to i zoo to 130o ° C. The so superheated water vapor is z. B. fed into a suitable generator in which water gas is continuously used can generate without the interposition of heating periods.
