Description

Verfahren zum Betrieb von Brennkraftmaschinen, insbesondere Dieselmotoren, mit pulverförmigen Brennstoffen Es ist schon vorgeschlagen worden, Verkokungsprodukte von Kohlearten zum Betrieb von Brennkraftmaschinen zu verwenden.Method for operating internal combustion engines, in particular diesel engines, with powdered fuels It has been proposed to use coking products of coal types to use for the operation of internal combustion engines.

Die vorliegende Erfindung betrifft ein verbessertes Verfahren zur Verwertung dieser Stoffe in Brennkraftmaschinen. Sie besteht darin, daß man heiße feste Verkokungsprodukte, insbesondere Schwelrückstände kohlenstoffhaltiger Stoffe, zusammen mit überhitztem Wasserdampf unter solchen Bedingungen der Temperatur verwendet, daß Wassergasbildung eintritt. Beispielsweise werden die Verkokungsrückstände, die bei der Verschwelung von Braunkohle erhalten wurden, durch geeignete Fördermittel unmittelbar aus dem Generator unter Luftabschluß über eine Mahlanlage, in der eine Aufbereitung zu Staub erfolgt, der Maschine, z. B. einem Dieselmotor, zugeführt. Vor dem Eintritt in die Maschine findet zweckmäßig eine Wärmezufuhr, z. B. durch stark überhitzten Wasserdampf oder Auspuffgase, statt, so daß die Temperatur des Kokses etwa 6oo ° beträgt. Alsdann erfolgt die Einführung der festen pulverförmigen Rückstände in die Maschine mit überhitztem Dampf, wobei der Dampf im Zylinderraum mit dem Brennstoff sofort unter Wassergasbildung reagiert. Der Brennstoff kann auch vor seiner Einführung in die Maschine derart mit Wasserdampf beladen werden, daß die einzelnen Brennstoffteilchen bei ihrem Eintritt in den Verbrennungsraum bereits von einem leicht entflammbaren Wassergasmantel umgeben sind. Das Wassergas bewirkt eine sofortige Zündung der Gas-Luft-Koks-Mischung. Es läßt sich auch z. B. derart arbeiten, daß man feste Verkokungsprodukte von gewöhnlicher Temperatur vor ihrem Eintritt in die Maschine vorwärmt und durch hochüberhitzten Wasserdampf auf eine für die Wassergasbildung geeignete Temperatur (6oo bis 7oo °) erhitzt. Der benötigte Wasserdampf kann z. B. durch die Auspuffwärme erzeugt werden.The present invention relates to an improved method for Utilization of these substances in internal combustion engines. It consists in being called solid coking products, in particular smoldering residues of carbonaceous substances, used together with superheated steam under such conditions of temperature, that water gas formation occurs. For example, the coking residues that in the smoldering of lignite were obtained through appropriate subsidies directly from the generator in the absence of air via a grinding plant in which one Processing to dust takes place, the machine, z. B. a diesel engine supplied. Before entering the machine, there is expediently a supply of heat, for. B. by strongly superheated steam or exhaust gases, instead, so that the temperature of the Coke is about 600 °. Then the solid powdery ones are introduced Residues in the machine with superheated steam, with the steam in the cylinder space reacts immediately with the fuel to form water gas. The fuel can too before its introduction into the machine are loaded with water vapor in such a way that the individual fuel particles as soon as they enter the combustion chamber are surrounded by a flammable water gas jacket. The water gas causes an immediate ignition of the gas-air-coke mixture. It can also be used, for. B. like this work that you can get solid coking products of ordinary temperature before their Entry into the machine is preheated and through highly superheated steam on a for the formation of water gas suitable temperature (6oo to 7oo °) heated. The one needed Water vapor can e.g. B. generated by the exhaust heat.

Vorteilhaft ist eine weitgehende Kombination von Motor und Verkokungsanlage im Sinne bestmöglicher Wärmeausnutzung; z. B. kann die Auspuffwärme auch zum Vortrocknen von Kohle für den Schwelprozeß verwendet und der Einblasedampf bei der Kühlung besonders heißer Teile im Generator gewonnen werden.An extensive combination of engine and coking plant is advantageous in terms of the best possible heat utilization; z. B. the exhaust heat can also be used for pre-drying of coal is used for the smoldering process and especially the injection steam for cooling hot parts can be obtained in the generator.

Man kann auch zur Unterstützung der Verbrennung kurz vor dem Einblasen der Verkokungsprodukte eine bestimmte Menge leicht brennbarer Stoffe, z. B. Braunkohle oder Öl oder brennbare Gase, in den Verbrennungsraum einführen.One can also help the combustion just before blowing it in the coking products contain a certain amount of easily flammable substances, e.g. B. lignite or oil or flammable gases into the combustion chamber.

An Hand der Zeichnung sei das Verfahren näher erläutert Aus dem Generator x fallen die heißen Schwelrückstände durch den Rost 2 in den Trog 3, aus dem sie mittels Fördervorrichtung ¢, die durch Leitung 5 unter Kohlensäure oder einem anderen Schutzgas gehalten werden kann, dem Mahlwerk 6 zugeführt werden. Eine Schnecke 7 befördert den gemahlenen Staub in den Trichter 8 über der Maschine. Förderschnecke und Trichter, eventuell auch Fördervorrichtung und Mahlwerk können z. B. durch die Auspuffgase beheizt werden. Der Staub wird durch das Staubventil g in eine Vorkammer eingeführt, von wo er beim Öffnen des Einblaseventils io mittels Heißdampfes aus der Leitung ii in den Verbrennungsraum eingeblasen wird. 12 ist das Austrittsventil.The method is explained in more detail with the aid of the drawing. From the generator x, the hot smoldering residues fall through the grate 2 into the trough 3, from which they are by means of conveying device ¢, which through line 5 under carbonic acid or another Protective gas can be kept, the grinder 6 are fed. A snail 7 conveys the ground dust into the hopper 8 above the machine. Auger and funnel, possibly also conveyor and grinder can, for. B. by the Exhaust gases are heated. The dust is passed through the dust valve g into an antechamber introduced, from where, when opening the injection valve io by means of superheated steam the line ii is blown into the combustion chamber. 12 is the outlet valve.
