Verfahren zum pneumatischen Fördern feinkörnigen Brennstoffes zu einem VergaserProcess for pneumatically conveying fine-grained fuel to a carburetor
Gegenstand der Erfindung ist ein Verfahren zum Betrieb einer Vorrichtung zur pneumatischen Förderung feinkörnigen Brennstoffes zu einem Vergaser, wobei in einen mit einer Einschleusvorrichtung versehenen Förderbehälter das Fördergas und daneben ein Druckhaltegas (Bespannungsgas) eingeführt werden und über Förderrohre den Brennstoff zum Vergaser führen.The invention relates to a method for operating a device for pneumatic conveying fine-grained Fuel to a gasifier, with the conveying gas in a conveying container provided with an infeed device and next to it a pressure holding gas (tensioning gas) are introduced and the fuel to the Lead carburetor.
Es ist bekannt, derartige Förderbehälter mit sogenannten Düsenstöcken zu versehen; darunter versteht man, in vertikaier Richtung verstellbare durch die Behälterwand hindurchgeführte Leitungsrohre für das Fördergas, wobei koaxial über dem oberen Rohrende ein gleichgroßes offenes Rohr angeordnet ist, das zur Förderung des Brennstoffes, einer gemahlenen und getrockneten Kohle,zum Vergaser dient. Der untere Rohrstutzen ist dabei um einen Betrag bis zu ι beispielsweise 50 mm verstellbar; die Höhe eines Ringspaltes zwischen den beiden Rohrenden kann auf diese Weise eingestellt, der Spalt kann auch verschlossen werden.It is known to provide such conveying containers with so-called nozzle assemblies; by that one understands, in vertikaier Direction of adjustable conduit pipes for the conveying gas, guided through the container wall, being coaxial An open pipe of the same size is arranged above the upper end of the pipe, which is used to convey the fuel, a ground and dried coal, used for the gasifier. The lower pipe socket is by an amount up to ι for example 50 mm adjustable; the height of an annular gap between the two pipe ends can in this way set, the gap can also be closed.
Die Aufgabe der vorliegenden Erfindung geht dahin, in mögliehst einfacher Weise die Menge des Brennstoffes zu regeln, der durch den Förderbehälter dem Vergaser zugeführt wird.The object of the present invention is as far as possible easy way to regulate the amount of fuel that is fed to the carburetor through the feed tank will.
Versuche an derartigen pneumatischen Förderern haben das überraschende Ergebnis gezeigt, daß eine Linearabhängigkeit zwischen der dem Vergaser durch die Förderbehälter und Vergaser verbindende Leitung zugeführten Menge an feinkörnigem Brennstoff und der Differenz des einerseits im Förderbehälter und andererseits im Vergaser herrschenden Druckes besteht.Tests on such pneumatic conveyors have shown the surprising result that a linear dependence between the line connecting the carburetor through the feed tank and carburetor quantity of fine-grained Fuel and the difference between the one prevailing in the delivery tank and the other in the carburetor Pressure exists.

Demgemäß geht der Vorschlag der Erfindung dahin, ein Gerät, das die genannte Druckdifferenz mißt, als Geber für die Regelung der dem Vergaser zugeführten Brennstoffmenge zu benutzen. Die Regelung kann beispielsweise dadurch erfolgen, daß der Mengenstrom des in den Förderbehälter eingeführten Druckhaltegases verändert wird. Die Regelung kann auch durch Einflußnahme auf andere Betriebsgrößen erfolgen, von denen die dem Förderrohr zugeführte Menge an Brennstoff abhängig ist.Accordingly, the proposal of the invention is a device that measures the said pressure difference, as a transmitter for the Control of the amount of fuel fed to the carburetor. The regulation can take place, for example, that the flow rate of the pressure holding gas introduced into the conveying container is changed. The regulation can also take place by influencing other operating parameters, of which the amount fed to the delivery pipe depends on fuel.
Das Gerät, das die Druckdifferenz mißt, steht in Verbindung mit einem Gerät, das auf den Sollwert einer bestimmten Druckdifferenz eingestellt ist, die der gewünschten Menge an geförderter Kohle entspricht. Bei Abweichungen vom Istwert wird ein Stellglied betätigt, mittels dessen der zugeführte Gasmengenstrom an Druckhaltegas verändert wird.The device, which measures the pressure difference, is in connection with a device, which on the setpoint of a certain Pressure difference is set, which corresponds to the desired amount of coal conveyed. If there are deviations from the actual value an actuator is actuated, by means of which the supplied gas flow rate is changed to pressure holding gas.
Auf der anliegenden Zeichnung ist in beispielsweiser Ausführung die Durchführung des neuen Verfahrens bei einer AnJ age zur Förderung feinkörnigen Brennstoffes zu einem Vergaser dargestellt.On the attached drawing is an example of the implementation of the new method in a AnJ age for the promotion of fine-grained fuel to a carburetor shown.
Rein schematisch sind ein Vergaser 10 und ein Druckbehälter 11 dargestellt. Mit 12 ist die in dem Druckbehälter befindliche Schüttung feinkörniger Kohle bezeichnet.A carburetor 10 and a pressure vessel 11 are shown purely schematically. With 12 is located in the pressure vessel Denotes pouring of fine-grained coal.
Mit 13 ist die mit einem Ventil 14 versehene Zuführungsleitung des Fördergases bezeichnet, auf welches ein mit 26 bezeichnetes Instrument zur Regelung der durchfließenden Gasmenge einwirkt. Mit 15 ist die Leitung zur Zuführung des Druckhaltegas-Mengenstromes bezeichnet. In dieser befindet sich ein Ventil 16. Durch eine Leitung 17 wird die Kohle vom Druckbehälter 11 zum Vergaser 10 gefördert.With 13 provided with a valve 14 feed line of the conveying gas is referred to, on which a with 26 designated instrument for regulating the amount of gas flowing through acts. At 15 is the line to the feed of the pressure-holding gas flow rate. In this there is a valve 16. Through a line 17 is the coal is conveyed from the pressure vessel 11 to the gasifier 10.
Der Leitungsabschnitt 13 und die Förderleitung 17 sind verbunden durch eine durch den Druckbehälter 11 geführteThe line section 13 and the delivery line 17 are connected by a through the pressure vessel 11

Leitung 18. In dieser ist innerhalb der Schüttung 12 eine Verschlußvorrichtung 19 vorgesehen, die so beschaffen ist, daß bei ihrer Offenstellung der feinkörnige Brennstoff aus der Schüttung 12 in die Leitung 18 und damit in die Förderleitung 17 gelangt.Line 18. In this a closure device 19 is provided within the bed 12, which is designed so that when it is open, the fine-grained fuel from the bed 12 into the line 18 and thus into the Delivery line 17 arrives.
20 ist ein Gerät, das einerseits über die Leitung 21 mit dem Druckbehälter 11 und andererseits über die Leitung 22 mit dem Vergaser 10 in Verbindung steht und die Differenz der in beiden Apparaten herrschenden Drücke mißt. Diese Druckdifferenz stellt das Maß für die durch die Leitung 17 geförderte Menge an feinkörnigem Gut dar. Die Menge des in der Zeiteinheit dem Vergaser 10 zugeführten Brennstoffes bestimmt die im Gerät 20 gemessene Druckdifferenz. Um die Brennstoffmenge konstant zu halten, ist es erforderlieh, für die Aufrechterhaltung eines bestimmten Wertes der Druckdifferenz zwischen Vergaser und Druckbehälter zu sorgen. Dieser Wert der Druckdifferenz wird dem Sollwertgeber 23 aufgegeben. Die Geräte 20 und 23 wirken auf den Regler 24 ein. Stellt dieser Abweichungen des von Gerät 20 gemessenen Istwertes von dem Sollwert fest, so beeinflußt er über die Leitung 25 das Ventil 16, und damit die Zufuhr des Druckhaltegases in solchem Sinne, daß für die Druckdifferenz zwischen Druckbehälter und Vergaser der vorgegebene Wert wieder hergestellt wird und damit die durch die Leitung 17 zum Vergaser geförderte Menge an feinkörnigem Brennstoff den vorgegebenen Wert hat.20 is a device that is connected on the one hand to the pressure vessel 11 via the line 21 and on the other hand via the line 22 is in communication with the carburetor 10 and measures the difference between the pressures prevailing in the two apparatuses. These Pressure difference represents the measure of that through the pipe 17 represents the amount of fine-grained material conveyed. The amount of fuel supplied to the carburetor 10 in the unit of time determines the pressure difference measured in device 20. In order to keep the amount of fuel constant, it is necessary to to maintain a certain value of the pressure difference between the carburetor and the pressure vessel care for. This value of the pressure difference is given to the setpoint generator 23. The devices 20 and 23 act on the Controller 24 on. If this determines deviations of the actual value measured by device 20 from the nominal value, it is influenced he via the line 25 the valve 16, and thus the supply of the pressure holding gas in such a sense that for the Pressure difference between pressure vessel and carburetor the specified value is restored and thus the The amount of fine-grained fuel conveyed through line 17 to the carburetor has the predetermined value.
Es leuchtet ein, daß diese Art der Regelung des Betriebes des Vergasers sehr einfach ist und nur einfacher Einrichtungen bedarf.It is evident that this way of regulating the operation of the carburetor is very simple and only simple facilities requirement.
