 sierte Asbestdichtungen. 



   Die durch die Erfindung erreichten Vorteile sind vor allem darin zu sehen, dass unmittelbar vor Eintritt der umzuformenden Stoffe in den eigentlichen Reaktionsraum,   d. h.   in die Ofenkammer, eine Überhitzung durchgeführt wird" wodurch eine überraschend gute Ausbeute gelingt, weil die Russbildung vermieden wird und folglich nicht durch Russbildung der Vergasungswirkungsgrad beeinträchtigt wird.

   Dabei werden bei dem   erfindungsgemässen Verfahren   infolge der erst unmittelbar vor der Kammer durchgeführten Überhitzung die Kohlenwasserstoffe gleichsam stossartig auf hohe Temperaturen dicht unterhalb der Zerfallstemperaturen erhitzt und dann in den Reaktionsraum eingeführt, wobei wahrscheinlich die umzufor-   menden Stoffe   in den aus   der Strahlungswärme der Kammern   beheizten und unmittelbar vor den Kammern angeordneten Erhitzerrohrschlangen nicht mehr die Zeit finden, zu kracken oder zu Russ zu koagulieren. 



  Erfindungsgemäss werden so in kurzen Zeitspannen die vorgewärmten Kohlenwasserstoffe in die Kammern zur Umformung eingeführt.

 sized asbestos seals.



   The advantages achieved by the invention are primarily to be seen in the fact that immediately before the substances to be formed enter the actual reaction space, i. H. in the furnace chamber, overheating is carried out "whereby a surprisingly good yield is achieved because the formation of soot is avoided and consequently the gasification efficiency is not impaired by soot formation.

   In the process according to the invention, as a result of the overheating carried out immediately in front of the chamber, the hydrocarbons are, as it were, suddenly heated to high temperatures just below the decomposition temperatures and then introduced into the reaction chamber, with the substances to be reshaped probably being in the chambers heated by the radiant heat of the chambers Heater coils arranged directly in front of the chambers no longer find the time to crack or to coagulate soot.



  According to the invention, the preheated hydrocarbons are introduced into the chambers for forming in short periods of time.

Claims

PATENT CLAIM: Process for the gasification of liquid gas and / or oil in gasworks or coke ovens, these substances evaporating and heated to a temperature as close as possible below the decomposition temperature before being introduced into the chamber, then introduced into the furnace chambers and gasified there in the sense of a water gas reaction are, characterized in that the heating of the substances to be gasified, possibly mixed with water vapor, in a heating pipe coil known per se, formed from the supply line for the substances to be gasified directly in front of the chamber in which the gasification takes place and heated by the radiant heat of the chamber, whose mouth is inserted into the chamber is made.
