Abstract
Verfahren der ORC-Kreislaufführung für Dampfprozesse dadurch gekennzeichnet, dass das durch mindestens zwei Wärmequellen unterschiedlicher Temperatur vorgewärmte und verdampfte dampfförmige ORC-Arbeitsfluid in mindestens zwei Arbeitstufen entspannt wird und zwischen zwei Arbeitsstufen mindestens einmal enthitzt wird und diese Enthitzungswärme zur Vorwärmung des ORC-Arbeitsfluides nach einer ersten Vorwärmung durch eine niedertemperaturige Wärmequelle und vor der Verdampfung durch eine höhertemperaturige Wärmequelle zugeführt wird.Process of ORC circulation for steam processes, characterized in that the at least two heat sources of different temperature preheated and vaporized vapor ORC working fluid is relaxed in at least two stages and is deintervened between two stages at least once and this Enthitzungswärme for preheating the ORC working fluid after a first preheating is supplied by a low-temperature heat source and before the evaporation by a higher-temperature heat source.
Description
Das erfindungsgemäße Verfahren zur Nutzung von mindestens zwei Wärmequellen mit unterschiedlicher Wärmemenge und -temperatur für mindestens zweistufige Turbinen oder sonstige Entspannungsmaschine erlaubt die Enthitzung des Arbeitsfluides nach einem ersten Entspannungsschritt derart, dass die bei der Enthitzung zurückgewonnene Wärmeenergie dem Arbeitsfluid oberhalb der Temperatur der ersten Wärmequelle wieder zugeführt werden kann.The inventive method to use at least two heat sources with different ones heat and temperature for at least two-stage turbines or other expansion machine allows the desuperheating of the working fluid after a first relaxation step such that the heat energy recovered during desuperheating the working fluid above the temperature of the first heat source fed again can be.
Der Stand der Technik ist dadurch gekennzeichnet, dass das Arbeitsfluid eines Dampfkreislaufes durch die Speisepumpe auf den gewünschten Druck gebracht wird und sodann nacheinander einen oder mehrere Vorwärmer, den Verdampfer und Überhitzer durchströmt und der dabei entstehende Dampf in einem oder mehreren Schritten entspannt wird und bei dieser Entspannung durch Kolbenmotoren, Schraubenmotoren oder Turbinen mechanische und dann elektrische Arbeit erzeugt wird. Bei herkömmlichen Dampfturbinen ist der Kreislauf bei Verwendung mehrstufiger Turbinen und bei Verwendung des Arbeitsmediums Wasser häufig zwischen den Turbinenstufen eine Zwischenüberhitzung vorgesehen, um eine Entspannung in den Nassdampfbereich vor oder in der nächsten Turbinenstufe zu vermeiden.Of the The prior art is characterized in that the working fluid a steam cycle through the feed pump to the desired Pressure is placed and then successively one or more preheater, the Evaporator and superheater flows through and the resulting vapor in one or more steps is relaxed and in this relaxation by piston engines, screw motors or Turbines mechanical and then electrical work is generated. at usual Steam turbines is the cycle when using multistage turbines and when using the working fluid, water frequently between the turbine stages a reheat intended to provide a relaxation in the wet steam area before or in the next Turbine stage to avoid.

Bei der Nutzung der Wärme unterschiedlicher Wärmequellen wie zum Beispiel bei einer Verbrennungskraftmaschine stellt sich die Frage der optimalen Nutzung der unterschiedlichen Wärmemengen bei unterschiedlichen Temperaturen. So liegt die Abgaswärme häufig zwischen 450°C bis 550°C an während die Motorabwärme, die Ölkühlung und die Ladeluftkühlung bei 90°C bis 105°C anfällt. Diese Wärmen sind mit dem Blick auf einen Dampfprozess bisher nur so zu vereinen, dass im Regelfall entweder ein kleiner Massenstrom des Arbeitsfluides zur Verdampfung bei hoher Temperatur gebracht werden kann oder ein grösserer Dampfmassenstrom bei relativ niedrigen Temperaturen von 115 bis 130°C. In beiden bekannten Fällen wird die zur Verfügung stehende Wärmemenge nicht optimal ausgenutzt.at the use of heat different heat sources such as in an internal combustion engine arises the question of the optimal use of different amounts of heat at different temperatures. So the exhaust heat is often in between 450 ° C to 550 ° C on while the engine waste heat, the oil cooling and the charge air cooling at 90 ° C up to 105 ° C accrues. These warms are so far to be united with the view of a steam process that usually either a small mass flow of the working fluid can be brought to evaporation at high temperature or a greater Steam mass flow at relatively low temperatures of 115 to 130 ° C. In both known cases will the available standing heat not optimally utilized.
Es stehen eine Reihe von Arbeitsfluiden für ORC-Prozesse zur Verfügung. Es können Kältemittel, auch fluorierte Kältemittel, Kohlenwasserstoffe, Siliconöle oder Thermoöle eingesetzt werden. Erfindungsgemäß sind insbesondere die ORC-Fluide von Interesse, die im P-h-Diagramm eine stark nach rechts geneigte Sattdampflinie aufweisen und die jeweiligen Isentropen weniger stark nach rechts geneigt sind. Diese ORC-Fluide haben die Eigenschaft, das eine adiabate Entspannung des Arbeitsfluides immer im überhitzten Bereich stattfindet und der Abstand zur Sattdampflinie mit zunehmender Entspannung sich immer weiter von der Sattdampflinie entfernt. Diese ORC-Arbeitsfluide müssen vor der Kondensation immer enthitzt werden.It There are a number of working fluids available for ORC processes. It can Refrigerants, too fluorinated refrigerants, Hydrocarbons, silicone oils or thermal oils be used. In particular, according to the invention the ORC fluids of interest, in the P-h diagram, a strongly inclined to the right saturated steam line and the respective isentropes less strongly to the right are inclined. These ORC fluids have the property of having an adiabatic Relaxation of the working fluid always takes place in the overheated area and the distance to the saturated steam line with increasing relaxation itself further away from the saturated steam line. These ORC working fluids have to Always be de-hydrated before condensation.
Bei ORC-Kreisläufen ist bisher vorgesehen, das die auf Grund der spezifischen nach rechts gerichteten Neigung der Sattdampflinie und einer etwas weniger nach rechts gerichteten Neigung der Isentropen anfallende Enthitzungswärme des Arbeitsfluides zur Vorwärmung des Arbeitsfluides nach der Speisepumpe wieder zu nutzen (s. a. Zeichnung 1 mit der Enthalpiedifferenz zwischen h9 und h10). Diese Enthitzungswärme steht in einem Temperaturbereich an, der sich im Regelfall mit dem Temperaturbereich der Motorabwärme schneidet.In ORC circuits is provided so far, that the due to the specific rightward inclination of the saturated steam line and a slightly less rightward tendency of isentropics accumulating Enthitzungswärme the working fluid for preheating the working fluid after the feed pump to reuse (sa see drawing 1 with the Enthalpy difference between h 9 and h 10 ). This heat of decay is in a temperature range which usually intersects with the temperature range of the engine waste heat.
Es ist aber wünschenswert sowohl die nach der Entspannung anfallende Enthitzungswärme, die Motorabwärme und die Abgaswärme möglichst vollständig zu nutzen.It but it is desirable both the heat of disinfestation arising after the release, the engine heat and the exhaust heat preferably Completely to use.
Dies gelingt erfindungsgemäß dadurch, dass nach einem ersten Entspannungsschritt des dampfförmigen Arbeitsfluides dieses Arbeitsfluid bis vor die Sattdampflinie enthitzt wird und diese Enthitzungswärme dem noch flüssigen Arbeitsfluid oberhalb der Temperatur aus der Motorabwärme zugeführt wird und sich erst dann ein zweiter Entspannungsschritt anschließt.This succeeds according to the invention in that after a first expansion step of the vaporous working fluid, this working fluid is de-pressurized up to the saturated steam line and this heat of dewatering is supplied to the still liquid working fluid above the temperature from the engine waste heat and only then then followed by a second relaxation step.
