"Verfahren zum Verhindern von aus flüssigen und/oder klebrigen Brennstoffaschepartikeln eines Produktgasstromes bestehenden Anbackungen beim Anströmen einer festen Begrenzung""Methods for preventing liquid and / or sticky fuel ash particles of a product gas flow existing caking when flowing against a fixed boundary "
Die Erfindung betrifft ein Verfahren zum Verhindern von aus flüssigen und/oder klebrigen Brennstoffaschepartikeln bestehenden Anbackungen eines aus einem Vergasungsprozeß kommenden, im Aufwärtsstrom gegen eine feste Begrenzung geführten heißen Produktgasstromes und anschließender Umlenkung.The invention relates to a method for preventing caking consisting of liquid and / or sticky fuel ash particles of a caking coming from a gasification process in an upward flow against a solid one Limitation of guided hot product gas flow and subsequent Redirection.
Es ist bekannt, daß in Krümmern herkömmlicher Bauart vor der Umlenkung des flüssige und/oder klebrige Brennstoffaschepartikel enthaltenen Produktgasstromes Anbackungen auftreten, die in unkontrollierbarer Weise den Betriebsablauf des Vergasungsprozesses beeinträchtigen und stören können.It is known that in manifolds of conventional design the deflection of the liquid and / or sticky fuel ash particles contained product gas stream caking occur that affect and disrupt the operation of the gasification process in an uncontrollable manner can.
Die vorliegende Erfindung hat sich die Aufgabe gestellt, ein Verfahren zu entwickeln, mit dem sichergestellt wird, daß Anbackungen aus flüssigen und/oder klebrigen Brennstoffaschepartikeln eines aus einem Vergasungsprozeß gegen eine feste Begrenzung geführten Produktgasstromes mit anschließender Umlenkung im Auftreffbereich an der festen Begrenzung[verhindert werden, weitgehendThe present invention has set itself the task of developing a method with which it is ensured that caking from liquid and / or sticky fuel ash particles a product gas flow passed from a gasification process against a fixed limit with subsequent deflection in the area of impact at the fixed boundary [can be prevented, largely
Diese Aufgabe wird dadurch gelöst, daß die Geschwindigkeit des Produktgasstromes und der in ihm enthaltenen flüssigen und/oder klebrigen Brennstoffaschepartikel vor Erreichen der festen Begrenzung unter den Wert der Sinkgeschwindigkeit der flüssigen und/oder klebrigen Brennstoffaschepartikel abgesenkt wird.This object is achieved in that the speed of the product gas stream and that contained in it liquid and / or sticky fuel ash particles before reaching the fixed limit below the value of the Sink rate of the liquid and / or sticky fuel ash particles is lowered.
Dadurch wird erreicht, daß die flüssigen und/oder klebrigen Brennstoffaschepartikel durch ihr Eigengewicht nach unten absinken und somit erst nach der Umlenkung an die feste Begrenzung gelangen. Anbackungen, die durch diese erfindungsgemäße Maßnahme außerhalb des Auftreffbereiches an der festen Begrenzung auftreten, können so auf vorteilhafte Weise mit Hilfe von Schlagoder Klopfeinrichtungen entfernt und aus der Gasumlenkeinrichtung abgeführt werden, wobei vermieden wird, daß große Stücke dieser Anbackungen in den Vergasungsprozeß zurückfallen und zur Betriebsstörung führen.This ensures that the liquid and / or sticky Fuel ash particles sink down due to their own weight and thus only after the deflection get to the fixed limit. Caking caused by this measure according to the invention outside of the The impact area at the fixed boundary can occur in an advantageous manner with the help of impact or Knocking devices are removed and discharged from the gas deflection device, avoiding that large pieces of this caking fall back into the gasification process and lead to operational disruptions.
Darüber hinaus wird aufgrund der Geschwindigkeitsverminderung der Gasströmung eine Durchmischung erzielt, die eine Vergleichmäßigung des Temperaturprofils des Produktgases nach dessen Umlenkung zur Folge hat.In addition, due to the reduction in the speed of the gas flow, thorough mixing is achieved which the result is an equalization of the temperature profile of the product gas after it has been deflected.
Die Erfindung wird im folgenden anhand eines in der beiliegenden Zeichnung Fig. 1 dargestellten Ausführungsbeispieles näher erläutert.The invention is described below with reference to an exemplary embodiment shown in the accompanying drawing FIG explained in more detail.
Ein aus einem Vergasungsprozeß kommender, flüssige und/ oder klebrige Brennstoffaschepartikel transportierender, heißer Produktgasstrom 1 strömt mit einer bestimmten Geschwindigkeit v* von unten nach oben in Richtung der festen Begrenzung 2. Nach Austritt des Produktgasstromes aus dem Pührungsrohr 3 in den Raum 4 verringert sich seine Geschwindigkeit durch Vergrößerung des freien Strömungsquerschnittes auf den Wert v„, der unter dem Wert der Sinkgeschwindigkeit ν der flüssigen und/oder klebrigen Brennstoffaschepartikel liegt. Dadurch sinken dieA liquid and / or sticky fuel ash particle that comes from a gasification process and transports, hot product gas stream 1 flows at a certain speed v * from bottom to top in the direction of the solid Limitation 2. After the product gas stream exits from the Pührungsrohr 3 in the space 4 is reduced its speed by increasing the free flow cross-section to the value v ", which is below the value is the rate of descent ν of the liquid and / or sticky fuel ash particles. As a result, the
noch flüssigen und/oder klebrigen Brennstoffaschepartikel nach unten, werden von dem umgelenkten Produktgasstrom 1 außerhalb des Auftreffbereiches 5 der festen Begrenzung 2 getragen und können dort anbacken. Mit Hilfe von Schlag- oder Klopfeinrichtungen 6 werden diese Anbakkungen von der festen Begrenzung entfernt und über eine schräge Fläche 7 oder mittels anderer Vorrichtungen aus der Gasumlenkeinrichtung abgeführt.fuel ash particles that are still liquid and / or sticky downwards, are of the deflected product gas stream 1 outside the impact area 5 of the fixed boundary 2 worn and can bake there. With the help of striking or knocking devices 6, these attachments away from the fixed boundary and over an inclined surface 7 or by means of other devices the gas deflector discharged.
