Abstract
Description
Die Erfindung betrifft einen Reaktor zur autothermen Vergasung von festen und flüssigen, aschehaltigen Brennstoffen mit einem freien Sauerstoff enthaltenden Vergasungsmitteln im Flugstrom bei Temperaturen bis 1.850°C und Drücken bis 10 MPa, wobei der Reaktor einen den Vergasungsraum begrenzenden Kühlmantel, einen Druckmantel und einen Quenchraum aufweist sowie ein Verfahren zum Betrieb des Reaktors.The invention relates to a reactor for the autothermal gasification of solid and liquid ash-containing fuels with a free oxygen-containing gasifying agents in the air stream at temperatures up to 1850 ° C and pressures up to 10 MPa, wherein the reactor has a gas jacket delimiting the cooling jacket, a pressure jacket and a quench and a method of operating the reactor.
Die Erfindung bezieht sich auf einen Reaktor zur Flugstromvergasung fester und flüssiger bzw. pastöser Brennstoffe mit einem freien Sauerstoff enthaltenden Oxidationsmittel unter normalem oder erhöhtem Druck bis 10 MPa. Feste Brennstoffe sind dabei zu Staub aufgemahlene Kohlen unterschiedlichen Inkohlungsgrades, Petrolkokse sowie andere mahlbare Feststoffe mit einem Heizwert größer 7 MJ/Nm3. Unter flüssigen Brennstoffen sind Öle oder Öl-Feststoff- oder Wasser-Feststoff-Suspensionen zu verstehen, wie beispielsweise Kohle-Wasser-Slurries. 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. 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
In der Patentanmeldung
Im Gebrauchsmuster
Daraus ergeben sich unter anderem unklare Wärmetransporte und Strömungsverhältnisse zwischen dem oberen und unteren Teil des Reaktors.This results in, among other things, unclear heat transport and flow conditions between the upper and lower part of the reactor.
Zur Überwindung dieses Nachteils wurde bereits in
Der Erfindung liegt die Aufgabe zu Grunde, die aus dem Vergasungsraum des Reaktors über die Kühlwand in den Kühlspalt übertragene Wärme in Form von Sattdampf unter annähernd Vergasungsdruck als nutzbare Energie zu gewinnen und somit einen höheren Wirkungsgrad zu erzielen.The invention is based on the object to win the heat transferred from the gasification chamber of the reactor via the cooling wall in the cooling gap in the form of saturated steam under approximately gasification pressure as usable energy and thus to achieve a higher efficiency.
Diese Aufgabe wird mit den Merkmalen des ersten Anspruches gelöst.This object is achieved with the features of the first claim.
Die wellenförmige Strukturierung des Kühlmantels bringt zum einen eine erhöhte Steifigkeit gegenüber Verformungen, die beispielsweise auf Druckunterschieden zwischen – Innenseite und Außenseite des Kühlmantels beruhen, zum zweiten eine Vergrößerung der Wärmeübergangsfläche zwischen Kühlmantel und Kühlmittel und zum weiteren eine Möglichkeit zum Längenausgleich temperaturbedingter unterschiedlicher Ausdehnungen mit sich.The wave-shaped structuring of the cooling jacket, on the one hand, results in increased rigidity against deformations which are based, for example, on pressure differences between the inside and outside of the cooling jacket, on the other hand an enlargement of the heat transfer surface between cooling jacket and coolant and, moreover, a possibility for length compensation of temperature-induced different expansion.
Werden die Stifte zur Fixierung der feuerfesten Stampfmasse senkrecht auf die Oberfläche des in sich gewellten Kühlmantels aufgebracht, so erfolgt eine formschlüssige Verankerung der Stampfmasse. If the pins are applied perpendicular to the surface of the corrugated cooling jacket for fixing the refractory ramming mass, a positive anchoring of the ramming mass takes place.
