Description
Die Erfindung betrifft eine Einrichtung zur Brenngaserzeugung durch Vergasung feinverteilter Brennstoffe in der Schwebe mit Sauerstoff und gegebenenfalls endotherm reagierenden Vergasungsmitteln.The invention relates to a device for generating fuel gas by gasifying finely divided fuels in suspension with oxygen and possibly endothermic gasifying agents.
Als Brennstoffe kommen sowohl feste Brennstoffe in Staubform als auch flüssige Brennstoffe in Dampfform oder in zerstäubter Form in Betracht. Als endotherm reagierende Vergasungsmittel können Wasserdampf oder Kohlendioxyd oder ein Gemisch dieser beiden Stoffe verwendet werden. Unter Sauerstoff im Sinne der Erfindung ist sowohl reiner Sauerstoff als auch mit Sauerstoff angereicherte Luft zu verstehen.Both solid fuels in dust form and liquid fuels in vapor form are used as fuels or in atomized form. Water vapor can be used as an endothermic gasifying agent or carbon dioxide or a mixture of these two substances can be used. Under oxygen in For the purposes of the invention, both pure oxygen and air enriched with oxygen are to be understood.
Bei derartigen Vergasungseinrichtungen wird ein Gemisch aus Brennstoff und Vergasungsmitteln durch eine brennerartige Düse in einen sich in Strömungsrichtung des Gemisches kegelig erweiternden Reaktionsraum eingeblasen. Dieser Reaktionsraum, gegebenenfalls auch mehrere solcher, öffnet sich in einen Gassammeiraum, aus dem das erzeugte Gas nach oben und die dort abgeschiedenen Vergasungsrückstände nach unten abgeführt werden. In such gasification devices, a mixture of fuel and gasification agents is through a burner-like nozzle into a reaction space that widens conically in the direction of flow of the mixture blown in. This reaction space, possibly also several such, opens into a gas collection room, from which the generated gas is discharged upwards and the gasification residues separated there downwards.
Bisher hat man Reaktionsraum und Gassammelraum als eine in sich abgeschlossene bauliche Einheit ausgebildet, d. h., der eigentliche Reaktionsraum war starr mit dem Gassammeiraum verbunden und machte dessen durch Wärmedehnungen bedingte Bewegung mit. Man wählte diese Ausführung im Hinblick darauf, daß die Gasdichtheit der ganzen Einrichtung durch einen alle Teile umschließenden Metallmantel erreicht werden sollte.So far, the reaction space and the gas collection space have been available as a self-contained structural unit trained, d. That is, the actual reaction space was rigidly connected to the gas collection space and made its movement caused by thermal expansion with. This design was chosen with a view to it that the gas-tightness of the entire device is ensured by a metal jacket surrounding all parts should be achieved.
Die starre Verbindung des Reaktionsraumes mit dem Gassammeiraum machte es notwendig, die Zufuhrleitungen der Reaktionsmedien mittels nachgiebiger Übergangselemente an die Brennerdüsen anzuschließen. Abgesehen davon, daß darin gewisse betriebliche Schwierigkeiten begründet waren, hatte die bekannte Einrichtung die unerwünschte Eigenschaft, daß zum Auswechseln oder zur Reparatur des am stärksten beanspruchten Reaktionsraumes häufig umfangreiche Demontagearbeiten notwendig waren.The rigid connection of the reaction space with the gas collection space made it necessary to use the supply lines the reaction media to be connected to the burner nozzles by means of flexible transition elements. Apart from the fact that it caused certain operational difficulties, the known device the undesirable property that to replace or repair the on the heaviest stressed reaction space, extensive dismantling work was often necessary.
Diese Schwierigkeiten werden gemäß der Erfindung dadurch behoben, daß der Reaktionsraum einerseits starr mit den Zufuhrleitungen für die Reaktionsmedien verbunden ist und andererseits mit dem Gassammeiraum in einer zwar gasdichten, aber im übrigen unstarren Verbindung steht, so daß der Gassammelraum gegenüber dem während des Betriebes ortsunveränderlich angeordneten Reaktionsraum durch Wärmedehnung bedingte Bewegungen ausführen kann.These difficulties are eliminated according to the invention in that the reaction space on the one hand is rigidly connected to the supply lines for the reaction media and on the other hand with the Gas collection space is in a gas-tight, but otherwise non-rigid connection, so that the gas collection space compared to the stationary reaction chamber during operation Can perform movements caused by thermal expansion.
Hierbei werden zweckmäßig sowohl der Reaktionsraum als auch der Gassammeiraum als je eine in sich geschlossene Baueinheit ausgebildet.In this case, both the reaction space and the gas collection space are expediently one per se formed closed structural unit.

findung näher erläutert wird. Die dargestellte Einrichtung ist zur Vergasung von feinverteilten festen Brennstoffen bestimmt; jedoch ändert sich an dem grundsätzlichen Aufbau nichts, wenn man statt des festen Brennstoffes beispielsweisie Kohlenwasserstofföl vergasen will. Lediglich die Konstruktion des außerhalb des Reaktionsraumes liegenden Brenners muß dem jeweiligen Brennstoff angepaßt werden.Finding is explained in more detail. The device shown is for the gasification of finely divided solid Fuels determined; however, nothing changes in the basic structure if one instead of the solid fuel for example wants to gasify hydrocarbon oil. Only the construction of the outside the burner located in the reaction chamber must be adapted to the respective fuel.
Die ganze Vergasungseinrichtung besteht aus dem sogenannten Brennerkopf 1 und dem Gassammelraum 2. Der Brennerkopf selbst wird gebildet durch das feuerfeste Mauerwerk 3., in welchem sich eine sich zum Gassammeiraum 2 hin kegelig erweiternde Aussparung 4 befindet. Diese Aussparung 4 ist der eigentliche Reaktionsraum, in dem die Umsetzungen zwisehen dem Brennstoff u[nd den Vergasungsmitteln ablaufen. Um die Temperatur des feuerfesten Mauerwerks 3 zu regulieren, ist eine Wasserkühlung 5 vorgesehen. The entire gasification device consists of the so-called burner head 1 and the gas collection chamber 2. The burner head itself is formed by the refractory brickwork 3. in which there is a to the gas collection space 2 conically widening recess 4 is located. This recess 4 is the actual one Reaction space in which the reactions between the fuel and the gasification agents expire. In order to regulate the temperature of the refractory masonry 3, a water cooling system 5 is provided.
Der Gassammeiraum 2 ist ebenfalls von feuerfestem Mauerwerk 6 gebildet, welches von einem Wassermantel 7 umgeben ist. Zum Brennerkopf 1 gehört ferner der eigentliche Brenner 8. Dieser besteht in vorliegendem Falle aus einer Schnecke 9, welche den feinverteilten festen Brennstoff in Richtung auf den Reaktionsraum 4 fördert. Durch die hohle Welle 10 der Schnecke 9 wird Sauerstoff unter leicht erhöhtem Druck zugeleitet. Durch die kegelige Ausbildung der Mundstücke des Brenners entsteht zwischen der hohlen Welle 10 und der Wand 11 des Schneckengehäuses ein gasdichter Stopfen aus Brennstaub, so daß Sauerstoff oder sonstige Gase nicht durch die Schnecke rückwärts strömen können. Beim Austritt des Sauerstoffs aus der hohlen Welle 10 reißt dieser den Brennstoff aus dem ringförmigenThe Gassammeiraum 2 is also formed by refractory masonry 6, which of a Water jacket 7 is surrounded. The actual burner 8 also belongs to the burner head 1 in the present case from a screw 9, which the finely divided solid fuel in the direction of the reaction chamber 4 promotes. Through the hollow shaft 10 of the screw 9, oxygen is slightly increased Pressure forwarded. The tapered design of the burner's mouthpieces creates between the hollow shaft 10 and the wall 11 of the screw housing from a gas-tight plug Fuel dust so that oxygen or other gases cannot flow backwards through the screw. When the oxygen emerges from the hollow shaft 10, it tears the fuel out of the annular shaft

Stopfen heraus und bildet mit ihm ein homogenes Gemisch, welches sich beim Eintritt in den auf erhöhter Temperatur befindlichen Reaktionsraum sofort entzündet. Das endotherm reagierende Vergasungsmittel wird durch den Ringraum 12 zugeführt und unter einer solchen Richtung in den Reaktionsraum eingeleitet, daß es die zentrale Zone der exothermen Reaktion zwischen Brennstoff und Sauerstoff mit einer sich in der gleichen Richtung bewegenden Hülle umgibt, die insbesondere das feuerfeste Mauerwerk vor einer übermäßigen Wärmebeanspruchung schützt und im übrigen mit dem glühenden, nicht vergasten Brennstoff in Reaktion tritt. Der Brennerkopf 1 ist auf einer Konsole 13 abgestützt und starr mit den Zufuhrleitungen der Reaktionsmedien verbunden. Der Gassammeiraum 2 ist an einer in der Zeichnung nicht sichtbaren Stelle so abgestützt, daß er Bewegungen, die durch die Wärmedehnung verursacht sind, ausführen kann. Um nun eine Gasdichtheit zwischen dem Brennerkopf 1 einerseits und dem Gassammeiraum 2 andererseits zu erreichen, ist eine Stopfbuchsendichtung 14 vorgesehen, welche einerseits Bewegungen von Brennerkopf und Gassammeiraum relativ zueinander zuläßt und andererseits Gasaustritte unterbindet. Die Stopfbuchsendichtung liegt in einem Bereich, in welchem keine hohen Temperaturen herrschen, so daß ein sicherer Betrieb dieser Dichtung gewährleistet ist.Stopper and forms with it a homogeneous mixture, which increases when entering the Temperature located reaction space ignited immediately. The endothermic gasifying agent is fed through the annular space 12 and under such a direction into the reaction space initiated that it is the central zone of the exothermic reaction between fuel and oxygen with a shell moving in the same direction, in particular surrounding the refractory masonry protects against excessive heat stress and otherwise with the glowing, not gassed Fuel reacts. The burner head 1 is supported on a console 13 and rigid with the Supply lines of the reaction media connected. The gas collection space 2 is not on one in the drawing visible point supported so that it executes movements caused by thermal expansion can. In order to achieve gas tightness between the burner head 1 on the one hand and the gas collection space 2 on the other hand, a gland seal 14 is provided, which on the one hand movements allows the burner head and gas collection space relative to each other and on the other hand prevents gas leaks. The stuffing box seal is in an area in which there are no high temperatures prevail, so that a safe operation of this seal is guaranteed.
Wenn an dem Gassammeiraum 2 mehrere Brennerköpfe der beschriebenen Art angeschlossen sind, so wird man diese Brennerköpfe zweckmäßigerweise miteinander starr verbinden, wobei die Art der Verbindung sich nach der Form des Gassammeiraumes richtet.If several burner heads of the type described are connected to the gas collection room 2, so you will conveniently connect these burner heads rigidly, the type of connection depends on the shape of the gas collection room.
Ist eine Auswechselung des Brennerkopfes 1 not wendig, so trennt man die Zufuhrleitung der Reaktionsmedien an einer beliebigen Stelle auf und kann dann den ganzen Brennerkopf aus dem Gassammelraum herausziehen.If it is necessary to replace the burner head 1, so one separates the feed line of the reaction media at any point and can then pull the entire burner head out of the gas collecting chamber.
