  Verfahren zur Verhütung von Zerstörungen der Wände von Verkokungskammern.

 <Desc/Clms Page number 2> 

 



   Die mit der Feuchtigkeit der Kohle an die Steine gelangende Menge der Alkalien ist nur gering, da nur die unmittelbar mit der Wand in   Berührung     kommende Kohlenschicht solche   an die Steine abgibt. Die Hauptmenge der Alkalien bleibt zunächst in Form von Hydroxyde im Einsatz liegen, bis eben bei   höherer   Temperatur die Sublimation und die Bindung durch den Kieselsäurezuschlag eintritt. 



   Es ist bereits vorgeschlagen, kieselsäurehaltigen Gichtstaub der zu verkokenden Kohle zuzusetzen. Da in dem Gichtstaub Kalk vorhanden ist, soll während der Verkokung eine Schlacke gebildet werden, die die Reduktion der ebenfalls in dem Gichtstaub enthaltenen Oxyde des Eisens erleichtert. Eine weitergehende Wirkung der Kieselsäure ist aber in diesem Vorschlag nicht angegeben ; insbesondere fehlt eine Angabe darüber, dass der Gichtstaub soviel Kieselsäure ent-

   The amount of alkalis that gets onto the stones with the moisture of the coal is only small, since only the layer of coal that comes into direct contact with the wall releases them to the stones. The majority of the alkalis initially remain in use in the form of hydroxides until sublimation and bonding by the silica additive occurs at a higher temperature.



   It has already been proposed to add silicic acid-containing gout dust to the coal to be coked. Since lime is present in the gout dust, a slag is supposed to be formed during the coking which facilitates the reduction of the iron oxides also contained in the gout dust. A more extensive effect of the silica is not specified in this proposal; In particular, there is no indication that the gout dust contained so much silica
