Abstract
Das Kleinkraftwerk mit äußerer Verbrennung lädt Wasser zur Dampfaufbereitung in einen Erhitzer 4, von wo der erzeugte Wasserdampf als Treibmedium in einer Strahlpumpe 6 Gas (Luft) als Saugmedium dem Fluidstrom hinzufügt und durch im Wasserdampf enthaltene Wärmeenergie ausdehnt. Dadurch wird der Volumenstrom vergrößert, weitere motorische Energie hinzugefügt und die Temperatur gesenkt. Gleichzeitig erhöht sich (im Falle des geschlossenen Systems) die Druckdifferenz, da die Luft auf der Gegendruckseite des Motors 8 entnommen wird.The small power plant with external combustion loads water for steam processing in a heater 4, from where the generated water vapor as a driving medium in a jet pump 6 adds gas (air) as suction medium to the fluid flow and expands it with the thermal energy contained in the water vapor. This increases the volume flow, adds more motor energy and lowers the temperature. At the same time (in the case of the closed system) the pressure difference increases, since the air is withdrawn from the counterpressure side of the motor 8.
Description
Kleinkraftwerke gibt es in den Varianten Windkraft, Photovoltaik, Wasserkraft oder als Verbrennungsmotoren für Kraftstoffe, die sich für die interne Verbrennung eignen. Biomasse, Sonnenwärme oder Abwärme aus anderen Prozessen werden unterhalb der Leistungsklassen von Turbinen noch nicht wirtschaftlich genutzt, und als Verdrängermotoren für äußere Verbrennung fristen die Dampfmaschine aus wirtschaftlichen und der Stirlingmotor aus technischen Gründen ein Nischendasein. Hydraulik- und Pneumatikmotoren funktionieren zwar in einem Fluidstrom bei geeignetem Druck und angemessener Temperatur, aber der konnte bisher mit äußerer Verbrennung nicht bereitgestellt werden.Small power plants are available in the variants wind power, photovoltaics, hydropower or as internal combustion engines for fuels that are suitable for internal combustion. Biomass, solar heat or waste heat from other processes are not yet used economically below the power class of turbines, and as displacement engines for external combustion, the steam engine eke out a niche existence for economic reasons and the Stirling engine for technical reasons. Hydraulic and pneumatic motors function in a fluid stream at the appropriate pressure and temperature, but external combustion has not previously been able to provide this.
Mit der hier vorgestellten Anordnung wird die Absicht verfolgt, einen Wandler so mit Gas anzuströmen, dass der Druck im günstigen Bereich liegt und die Temperatur unschädlich ist. Dabei soll das Fluid selbst umweltverträglich sein, innerhalb der Anordnung über Erhitzung, Ausdehnung, Leistungsabgabe und Kondensation einen Kreislauf bilden, aber gleichzeitig ein genügend hohes Druckgefälle ermöglichen.With the arrangement presented here, the intention is to flow gas to a transducer in such a way that the pressure is in the favorable range and the temperature is harmless. The fluid itself should be environmentally friendly, form a cycle within the arrangement via heating, expansion, power output and condensation, but at the same time allow a sufficiently high pressure gradient.
Die vorliegende Erfindung beschreibt demnach einen Kreislauf mit zwei Fluiden, Gas und Wasser, die in der Arbeitsphase gemeinsam und als Gasgemisch (Wasserdampf und Luft) erscheinen, und in der Ladephase getrennt als Wasser und Gas behandelt werden.The present invention accordingly describes a cycle with two fluids, gas and water, which appear together in the working phase and as a gas mixture (water vapor and air) and are treated separately as water and gas in the loading phase.
Das folgende Ausführungsbeispiel soll die Funktionsweise näher erläutern.The following exemplary embodiment is intended to explain the mode of operation in more detail.
Die Ladepumpe
Zudem wird das für die Leistung des Motors entscheidende Druckgefälle dadurch erhöht, dass die Entnahme der gekühlten Luft aus dem Kondensator
Es werden also mit dem erfindungsgemäßen Einsatz der Strahlpumpe mehrere wünschenswerte Effekte erzielt:
- - Die Dampftemperatur vor dem Motor sinkt auf ein materialverträgliches Maß.
- - Weitere enthaltene Wärmeenergie wandelt sich in motorische Energie.
- - Der Gegendruck in
Behälter 3 und7 wird gesenkt, das Druckgefälle steigt. - - Der Volumenstrom vor dem Motor nimmt zu.
- - The steam temperature in front of the engine drops to a level that is compatible with the material.
- - Further contained thermal energy is converted into motor energy.
- - The back pressure in the
container 3 and7th is lowered, the pressure gradient increases. - - The volume flow in front of the motor increases.
Ein weiterer Vorteil dieser Anordnung besteht darin, dass sie auch an vorhandene (Biomasse-)Heizanlagen angebaut werden kann. Wenn die Stromgewinnung Vorrang haben soll, kann der Hersteller oder Anwender die Wärmetauscher so arrangieren, dass in erster Linie Dampf erzeugt und nur die Restenergie aus dem Kondensator zur Heizung verwendet wird.Another advantage of this arrangement is that it can also be attached to existing (biomass) heating systems. If electricity generation is to have priority, the manufacturer or user can arrange the heat exchangers so that primarily steam is generated and only the residual energy from the condenser is used for heating.
Die Anordnung kann auch im offenen System betrieben werden, indem Luft aus der Umwelt als Saugmedium dient und diese direkt oder hinter dem Kondensator wieder an die Umwelt abgegeben wird.The arrangement can also be operated in an open system in that air from the environment serves as the suction medium and this is released back to the environment directly or behind the condenser.
