Description
Die Erfindung betrifft eine Anlage zum Betrieb einer Brenn kraftmaschine mit gasförmigem Brennstoff aus Vergasungsanla gen, z. B. für Holz oder Müll, oder verfahrenstechnischen Pro zessen, z. B. zur Kunststoffherstellung, mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to a system for operating a burner Engine with gaseous fuel from gasification plant gene, e.g. B. for wood or garbage, or process engineering pro zessen, z. B. for plastic production, with those in the preamble of claim 1 specified features.
Bei den Anlagen dieser Art, die z. B. durch die DE-PS 31 49 839 bekanntgeworden sind, ist der Kühler dem Verdichter für die Verbrennungsluft unmittelbar nachgeordnet und so ausgelegt, daß er die im Verdichter erhitzte Luft auf die für die Brenn kraftmaschine noch zulässige Ladetemperatur von höchstens 50° C herunterkühlt.In the plants of this type, the z. B. by DE-PS 31 49 839 have become known, the cooler is the compressor for the Combustion air immediately downstream and designed so that he heated the air in the compressor to that for burning permissible charging temperature of maximum 50 ° C. cools down.
Derartige Anlagen arbeiten zufriedenstellend, wenn die Tempe ratur des Brenngases beim Eintritt in die Mischvorrichtung nicht über 50°C beträgt, weil dann die Temperatur des Brenngas- Luft-Gemisches ebenfalls die genannte Ladetemperatur nicht übersteigt. Liegt jedoch ein Brenngas vor, dessen Temperatur beim Austritt aus dem Gaserzeuger wesentlich über 50°C, z. B. 200°C, beträgt, so muß ein zusätzlicher Kühler eingesetzt werden, der zwischen Gaserzeuger und Mischvorrichtung einzu schalten ist, und der naturgemäß einen zusätzlichen apparati ven und steuerungstechnischen Aufwand bedingt.Such systems work satisfactorily when the tempe rature of the fuel gas when entering the mixing device is not above 50 ° C, because then the temperature of the fuel gas Air mixture also does not have the stated charging temperature exceeds. However, if there is a fuel gas, its temperature when leaving the gas generator significantly above 50 ° C, z. B. 200 ° C, an additional cooler must be used be the one between the gas generator and the mixing device switch, and of course an additional apparatus ven and control engineering expenses.
Der Erfindung liegt die Aufgabe zugrunde, diesen Mangel zu beheben oder zumindest zu verringern und demgemäß die eingangs genannten bekannten Anlagen dahingehend weiter auszugestalten, daß ein zusätzlicher Kühler auch dann nicht erforderlich ist, wenn die Eintrittstemperatur des Brenngases in die Mischvor richtung wesentlich mehr als 50°C beträgt. The object of the invention is to overcome this defect fix or at least reduce and accordingly the beginning to further develop the known systems mentioned, that an additional cooler is not necessary even when the entry temperature of the fuel gas into the mixing device direction is significantly more than 50 ° C.
Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß der Kühler stromabwärts der Mischvorrichtung und stomauf wärts der Brennkraftmaschine angeordnet ist.To solve this problem, the invention proposes that the cooler is downstream of the mixer and upstream is arranged the internal combustion engine.
Durch diese Verlagerung des einzigen Kühlers vor die Brenn kraftmaschine wird zudem erreicht, daß in dem Wärmeaustauscher des Kühlers zwangsläufig eine turbulente Strömung entsteht, durch welche die Folgen einer eventuellen unvollständigen Vermischung in der Mischvorrichtung, wie Unregelmäßigkeiten in der Zylinderversorgung der Brennkraftmaschine, verringert wird.By relocating the single cooler in front of the burner Engine is also achieved in the heat exchanger the cooler inevitably creates a turbulent flow, through which the consequences of a possible incomplete Mixing in the mixing device, such as irregularities in the cylinder supply to the internal combustion engine becomes.
In den Unteransprüchen sind vorteilhafte Weiterbildungen des Gegenstandes des Anspruchs 1 gekennzeichnet.Advantageous further developments of the Subject of claim 1 characterized.
So soll gemäß den Ansprüchen 2 und 3 verhindert werden, daß bei der Abkühlung in dem Kühler als Kondensat anfallende Be gleitstoffe des Brenngases, wie Naphthalin oder Phenolverbin dungen, sich an den Wandungen des Wärmeaustauschers absetzen und den Wärmeübergang verschlechtern.So according to claims 2 and 3 is to be prevented that when cooling in the cooler as condensate Be lubricants in the fuel gas, such as naphthalene or phenol compound deposits on the walls of the heat exchanger and worsen the heat transfer.
Nach dem Anspruch 4 soll eine weitere Intensivierung des Mischvorgangs bereits in der Mischvorrichtung erreicht werden.According to claim 4, a further intensification of Mixing process can already be achieved in the mixing device.
In der Zeichnung ist die erfindungsgemäße Anlage anhand einer schematisierten Darstellung veranschaulicht, wobei diejenigen Teile der Anlage fortgelassen sind, die zwar in einer prakti schen Ausführung erforderlich oder erwünscht sind, wie z. B. Steuer-, Regel- und Schaltorgane, die jedoch einerseits dem einschlägigen Fachmann geläufig und andererseits für die Er läuterung des Gegenstandes der Erfindung entbehrlich sind.In the drawing, the system according to the invention is based on a Schematic diagram illustrates those Parts of the system are omitted, which in a practical rule execution are required or desired, such as. B. Control, regulating and switching elements, which, however, on the one hand relevant specialist familiar and on the other hand for the Er clarification of the object of the invention are unnecessary.
Mit 1 ist eine Brennkraftmaschine für Betrieb mit gasförmigem Brennstoff, im folgenden "Gasmotor für Brenngas" genannt, bezeichnet, an den eine Abgasturbine 2 angeschlossen ist, die über Kraftübertragungsmittel 3 einen Verdichter 4 antreibt (Abgasturbolader). Dem Verdichter 4 ist ein Luftfilter 5 vor geschaltet, der eintrittseitig bei 6 die erforderliche Ver brennungsluft, auch Ladeluft genannt, für den Gasmotor 1 aus der Atmosphäre entnimmt. Dem Verdichter 4 ist eine Mischvor richtung 7 nachgeschaltet, in der eine Vermischung der Lade luft mit dem Brenngas stattfindet, das aus einem Gaserzeuger 8 stammt und der Mischvorrichtung 7 zugeleitet wird. Im vor liegenden Ausführungsbeispiel weist das Brenngas bei ihrem Eintritt in die Mischvorrichtung 7 eine Temperatur von ca. 200°C auf. Dementsprechend weist die Verbrennungsluft bei ihrem Eintritt in die Mischvorrichtung 7 eine Temperatur von < 200°C auf. Um den Mischvorgang der beiden Medien möglichst zu intensivieren, ist die Mischvorrichtung 7 im vorliegenden Fall nach Art eines Venturirohrs 7' ausgebildet, derart, daß als treibendes Medium die Verbrennungsluft und als getriebenes Medium das Brenngas wirken. Zwischen Mischvorrichtung 7 und dem Gasmotor 1 ist ein Kühler 9 eingeschaltet, in welchem das Ladeluft-Brenngas-Gemisch auf die für Gasmotoren übliche Lade temperatur unter 50°C heruntergekühlt wird. Durch diese Anord nung des Kühlers 9 unmittelbar vor dem Gasmotor 1 wird gegen über der eingangs genannten bekannten Anordnung des Kühlers zwischen Verdichter und Mischvorrichtung erreicht, daß bei Anlieferung des Brenngases als Heißgas ein zusätzlicher Kühler zwischen Gaserzeuger und Mischvorrichtung entbehrlich ist. Für den Fall, daß das Heißgas außerdem mit sogenannten Gasbegleit stoffen, z. B. höher siedenden Kohlenwasserstoffen, wie Naph thalin oder Phenolverbindungen, behaftet ist, ist gemäß der dargestellten Ausführungsart zwischen Mischvorrichtung 7 und Kühler 9 eine Einrichtung zum Eindüsen 10 von organischen Lösungsmitteln, z. B. Heizöl, eingeschaltet. Hiermit werden an den von dem Brenngas-Luft-Gemisch bestrichenen Wärmeaustausch flächen des Kühlers 9 aufgrund von Kondensation /Kristallisa tion evtl. niedergeschlagene Teile der genannten Gasbegleit stoffe weggelöst und im Gasmotor 1 energetisch genutzt. Der Eindüsungsvorgang erfolgt zweckmäßig jeweils bei Teillastbe trieb des Gasmotors 1 in bestimmten Zeitabständen. 1 with an internal combustion engine for operation with gaseous fuel, hereinafter referred to as "gas engine for fuel gas", to which an exhaust gas turbine 2 is connected, which drives a compressor 4 via power transmission means 3 (exhaust gas turbocharger). The compressor 4 has an air filter 5 connected in front of it, which on the inlet side at 6 removes the necessary combustion air, also called charge air, for the gas engine 1 from the atmosphere. The compressor 4 is a Mischvor direction 7 downstream, in which a mixing of the charging air takes place with the fuel gas, which comes from a gas generator 8 and the mixing device 7 is fed. In the exemplary embodiment lying before, the fuel gas has a temperature of approximately 200 ° C. when it enters the mixing device 7 . Accordingly, the combustion air has a temperature of <200 ° C. when it enters the mixing device 7 . In order to intensify the mixing process of the two media as much as possible, the mixing device 7 in the present case is designed in the manner of a Venturi tube 7 ', such that the combustion air acts as the driving medium and the fuel gas acts as the driven medium. Between the mixing device 7 and the gas engine 1 , a cooler 9 is switched on, in which the charge air / fuel gas mixture is cooled down to the charging temperature customary for gas engines below 50 ° C. By this arrangement of the cooler 9 directly in front of the gas engine 1 , compared to the known arrangement of the cooler between the compressor and the mixing device mentioned above, that an additional cooler between the gas generator and the mixing device is unnecessary when the fuel gas is delivered as hot gas. In the event that the hot gas also substances with so-called gas accompanying z. B. higher-boiling hydrocarbons, such as naphthalene or phenol compounds, is, according to the embodiment shown between the mixing device 7 and cooler 9, a device for injection 10 of organic solvents, for. B. heating oil switched on. In this way, at the heat exchange surfaces of the cooler 9 which are smeared by the fuel gas / air mixture, parts of the abovementioned gas accompanying substances which may have precipitated due to condensation / crystallization are removed and used energetically in the gas engine 1 . The injection process is expediently carried out at partial load of the gas engine 1 at certain time intervals.
