Description
Die Erfindung betrifft einen Reaktor zur Vergasung von festen und flüssigen Brennstoffen im Flugstrom bei Temperaturen zwischen 1.200 und 1.900°C und Drucken zwischen Umgebungsdruck und 10 MPa (100 bar) mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a reactor for the gasification of solid and liquid Fuels in the stream at temperatures between 1,200 and 1,900 ° C and pressures between ambient pressure and 10 MPa (100 bar) with the Features of the preamble of claim 1.

In
der Technik der Gaserzeugung aus festen Brennstoffen ist die autotherme
Flugstromvergasung langjährig bekannt. Das Verhältnis
von Brennstoff zu sauerstoffhaltigem Vergasungsmittel wird dabei
so gewählt, dass man Temperaturen erreicht, die über dem
Schmelzpunkt der Asche liegen und Werte zwischen 1200 und 1900°C
erreichen können. Dann wird die Asche zu flüssiger
Schlacke aufgeschmolzen, die gemeinsam mit dem Vergasungsgas oder getrennt
den Vergasungsraum verlässt und anschließend direkt
oder indirekt gekühlt wird. Eine solche Vorrichtung geht
aus
Eine
ausführliche Beschreibung eines solchen mit einem Kühlschirm
ausgerüsteten Vergasungsreaktors findet sich in
Die Wärmedämmung zwischen dem heißen Vergasungsraum und dem Kühlschirm übernehmen eine feste Schlackeschicht, sowie ein langsam an der Wand abfließender zähflüssiger Schlackefilm, dessen Entstehung jedoch einen bestimmten Aschegehalt im Brennstoff voraussetzt. Ist dieser nicht gegeben, kann es zu erhöhtem Wärmeeintrag in den Kühlschirm und ggf. zu dessen Zerstörung führen.The Thermal insulation between the hot gasification room and the cooling screen adopt a solid slag layer, and a slowly flowing on the wall viscous Slag film, whose emergence, however, a certain ash content in the fuel presupposes. If this is not given, it can happen increased heat input into the cooling screen and possibly lead to its destruction.
Aufgabe der vorliegenden Erfindung ist die Vermeidung der genannten Nachteile.task The present invention avoids the disadvantages mentioned.
Erfindungsgemäß werden diese Nachteile durch die in Anspruch 1 genannte Lösung überwunden.According to the invention overcome these disadvantages by the solution mentioned in claim 1.
Erfindungsgemäß wird
der Ringspalt
Werden
aschefreie oder aschearme Brennstoffe eingesetzt, die keine oder
nur eine geringe wärmeisolierende Wirkung zur Folge haben,

- – zwischen dem Druckmantel
1 des Vergasungsreaktors und dem Kühlschirm8 befindet sich ein Kühlschirmspalt2 , der mit einer bindenden Feuerfestauskleidung auf der Basis einer SIC(Siliciumcarbid)-Stampfmasse ausgefüllt ist - – der Kühlschirm
8 ist mit gasdicht verschweißten, wassergekühlten Rohren3 gebildet, die mit Stiften4 versehen sind - – auf dem Kühlschirm
8 befindet sich eine aus SIC bestehende Stampfmasse5 , die durch einen Brennprozess während der Erstaufheizung sehr fest auf der Oberfläche des Kühlschirmes8 haftet - – durch die beim Vergasungsprozess aufgeschmolzene
Kohlenasche bildet sich eine feste Schlackeschicht
9 , die den Hauptteil der Wärmeisolation trägt - – an der Innenseite der festen Schlackeschicht
9 bildet sich ein Schlackefilm7 , der durch auftreffende Schlacke immer wieder erneuert wird, nach unten strömt und gemeinsam mit dem Vergasungsgas aus dem Reaktor ausgetragen wird - – die Wärmeübertragung auf dem Kühlschirm
8 wird auf 150 KW/m2 begrenzt - – der Kühlschirmspalt
2 ist gegen das Eindringen von Kondensat geschützt - – die Wärmeausdehnung zwischen dem Druckmantel
1 und dem Kühlschirm8 ist so gering, dass eine feste, gasdichte Verbindung zwischen dem Druckmantel1 und dem Kühlschirm8 hergestellt werden kann.

8th is with gas-tight welded, water-cooled pipes3 formed with pins4 are provided - - on the cooling screen
8th there is a rammed mass consisting of SIC5 caused by a burning process during initial heating very firmly on the surface of the cooling screen8th liable - - By the molten during the gasification process coal ash forms a solid slag layer
9 , which carries the main part of the heat insulation - - on the inside of the solid slag layer
