Description
Definitiondefinition
Als Feuerung wird hier ein System bezeichnet, in dem durch Zufuhr von Luft ein Medium fest, flüssig, oder gasförmig oxidiert wird und hierdurch Abgase, so genannte Rauchgase, entstehen, deren Temperatur erheblich über der der zugeführten Luft liegt.Firing here is a system in which by the supply of air, a medium solid, liquid, or gaseous oxidized and thereby exhaust gases, so-called flue gases, arise whose temperature is significantly higher than that of the supplied air.
Die heißen Abgase werden als Rauchgas bezeichnet.The hot exhaust gases are called flue gas.
Eine ORC-Anlage ist durch das Vorhandensein von Verdampfern, Kondensatoren, Turbinen und Pumpen gekennzeichnet, in denen ein anderes Medium als Wasser, das so genannte Arbeitsmittel, zum Zwecke der Umwandlung von thermischer in elektrischer Energie die Zustände von flüssig zu gasförmig und umgedreht wechselt.An ORC system is characterized by the presence of evaporators, condensers, turbines and pumps in which a medium other than water, the so-called working fluid, changes states from liquid to gaseous and vice versa for the purpose of converting thermal energy into electrical energy.
Mit ORC-Wärmetauscher wird hier der Wärmetauscher oder das Wärmetauschersystem bezeichnet, über das die thermische Energie auf das Arbeitsmittel der ORC-Anlage übertragen wird.ORC heat exchangers refer to the heat exchanger or heat exchanger system, through which the thermal energy is transferred to the working fluid of the ORC system.
Rauchgas ist das gasförmige Verbrennungsprodukt aus dem der Feuerung zugeführten Brennstoff und Luft. In ihm ist vor der Nutzung ein großer Teil der durch die Verbrennung frei werdenden Wärme enthalten.Flue gas is the gaseous product of combustion from the fuel and air supplied to the furnace. It contains a large part of the heat released by the combustion before use.
Anwendungapplication
Zur Erzeugung von Strom mittels Kraft-Wärmekopplung aus Biomasse wird in kleinen Systemen häufig eine Feuerung, z. B. für den Brennstoff Holz, mit einer ORC-Anlage gekoppelt. Die aus der ORC-Anlage abgegebene Wärme wird meist in ein Wärmenetz gespeist.In order to generate electricity by means of combined heat and power from biomass is in small systems often a furnace, for. B. for the fuel wood, coupled with an ORC system. The heat released from the ORC system is usually fed into a heat network.
Die von der Feuerung abgegebene Wärmeleistung wird durch Änderung der Brennstoffzufuhr an den Bedarf des Wärmenetzes nach der ORC-Anlage angepasst.The output of heat from the furnace is adjusted by changing the fuel supply to the needs of the heating network after the ORC system.
Die ORC-Anlage erzeugt soviel Strom, wie aus der zugeführten Energie möglich ist. Die Abwärme der Anlage wird meist vollständig zum Heizen verwendet.The ORC system generates as much power as is possible from the supplied energy. The waste heat of the system is usually used completely for heating.
Bei der beschriebenen Anordnung wird auf einen üblicherweise zwischen Feuerung und ORC-Anlage geschalteten Kreislauf von Wärmeträgeröl verzichtet und das ORC-Medium durch heiße Rauchgase direkt verdampft. Um beim Arbeitsmedium der ORC-Anlage eine zu hohe thermische Beanspruchung durch das heiße Rauchgas zu verhindern, wird dem Rauchgas soviel bereits abgekühltes Rauchgas beigemischt, dass die Eintrittstemperatur in die ORC-Anlage ein Optimum aufweistIn the described arrangement is dispensed with a usually switched between firing and ORC system circulation of heat transfer oil and the ORC medium directly evaporated by hot flue gases. In order to prevent too high thermal stress from the hot flue gas in the working medium of the ORC system, the flue gas is admixed with so much already cooled flue gas that the inlet temperature into the ORC system has an optimum
Durch den einfachen apparativen Aufbau des Gesamtsystems werden die Investitions- und Betriebskosten gesenkt und der Einsatz auch in noch kleineren Leistungsbereichen möglich.The simple design of the entire system reduces the investment and operating costs and makes it possible to use even in smaller power ranges.
Stand der TechnikState of the art
Bekannte Kombinationen von Biomassefeuerungen und ORC-Anlage sind dadurch gekennzeichnet, dass zwischen ORC-Anlage und Biomassefeuerung ein Thermoölsystem geschaltet ist, welches die thermische Leistung der Feuerung in die ORC-Anlage überträgt.Known combinations of biomass furnaces and ORC plant are characterized in that between the ORC plant and biomass firing a thermal oil system is connected, which transmits the thermal power of the furnace in the ORC plant.
In der Feuerung entstehen Rauchgase mit Temperaturen von oft bis zu 1000°C. mit diesen Rauchgasen wird ein Wärmeträgeröl auf ca. 300°C erwärmt und durch den Wärmetauscher einer ORC-Anlage gepumpt. Das Öl kühlt sich hierbei ab und das Arbeitsmedium der ORC-Anlage wird vorgewärmt und verdampft.The combustion produces flue gases with temperatures of often up to 1000 ° C. With these flue gases, a heat transfer oil is heated to about 300 ° C and pumped through the heat exchanger of an ORC plant. The oil cools down and the working medium of the ORC system is preheated and evaporated.
Der Dampf des Arbeitsmediums wird über einer Turbine auf einen geringeren Druck entspannt, kondensiert und mittels eine so genannten Speisepumpe wieder in den Verdampfer gepumpt. Die Turbine treibt einen Generator, welcher elektrische Energie ins netz liefert.The vapor of the working medium is expanded by a turbine to a lower pressure, condensed and pumped by means of a so-called feed pump back into the evaporator. The turbine drives a generator, which supplies electrical energy to the grid.
Die bei der Kondensation abgegebene Wärme wird über einen Kühlwasserkreis in ein Wärmenetz gespeist.The heat released during the condensation is fed into a heat network via a cooling water circuit.
Damit das Thermoöl durch das heiße Rauchgas nicht in seiner Struktur zerstört wird, muss es permanent durch den Wärmetauscher gepumpt werden. Hierfür ist zusätzliche elektrische Energie notwendig.So that the thermal oil is not destroyed by the hot flue gas in its structure, it must be pumped through the heat exchanger permanently. This requires additional electrical energy.

Man erkennt, dass die Erfindung sich erheblich vom geschilderten Stand der Technik unterscheidet und zahlreiche Vorteile aufweist:In the accompanying schematic drawings, the basic structure and function of the new system will be apparent. It will be appreciated that the invention differs significantly from the prior art described and has numerous advantages:
Beschreibung der Erfindung Description of the invention
Oft weist das direkt aus der Feuerung stammende Rauchgas eine zu hohe Temperatur aus, um damit im Wärmetauscher der ORC-Anlage ein ORC-Arbeitsmedium zu erwärmen. Zur Feuerung gehörige so genannte Rezirkulationsgebläse dienen lediglich der Regelung der Verbrennung, ohne jedoch die Rauchgastemperatur maßgeblich zu beeinflussen.Often, the flue gas coming directly from the furnace has too high a temperature in order to heat up an ORC working medium in the heat exchanger of the ORC plant. The so-called recirculation blower associated with firing serves merely to control the combustion, but without significantly influencing the flue gas temperature.
