Abstract

The procedure for the production of electricity, heat and hydrogen and/or methanol, comprises coupling an oxyfuel-steam power plant with a modular high temperature reactor (MHTR) power plant in such a way that the oxygen emerging in the MHTR power plant part in an electrolysis process is introduced in steam boiler plant (3) of the oxyfuel-steam power plant and the heat emerging in the MHTR power plant is brought in a heating boiler plant (8) of the oxyfuel-steam power plant. The oxygen is produced under avoiding the development of carbon dioxide in the MHTR power plant. The procedure for the production of electricity, heat and hydrogen and/or methanol, comprises coupling an oxyfuel-steam power plant with a modular high temperature reactor (MHTR) power plant in such a way that the oxygen emerging in the MHTR power plant part in an electrolysis process is introduced in steam boiler plant (3) of the oxyfuel-steam power plant and the heat emerging in the MHTR power plant is brought in a heating boiler plant (8) of the oxyfuel-steam power plant. The oxygen is produced under avoiding the development of carbon dioxide in the MHTR power plant over high-pressure water electrolysis and/or high-temperature steam electrolysis and is mixed with gas stream, which is required in the oxyfuel-steam power plant for the combustion fuel or biogenic fuels. The steam of the heating boiler of the MHTR power plant is coupled in medium pressure section of main turbine of the oxyfuel-steam power plant. The heating boiler is conveyed in floating-pressure operation during standard operation of the plant. The pressure regulation of the steam turbine is carried out through water injection into the steam of the heating boiler.

Description

Die Erfindung betrifft ein Verfahren zur Erzeugung von Strom, Wärme und Wasserstoff bzw. Methanol durch ein abgestimmtes Betreiben von unterschiedlichen Kraftwerkstypen und entsprechenden Zusatzanlagen in einem neuen, räumlich zusammengehörigen Gesamt-Kraftwerkskomplex. Als Primärenergieträger kommen fossile Brennstoffe (vorrangig Braun- und Steinkohle sowie biogenes Brennmaterial) und Kernbrennstoffe zum Einsatz.The The invention relates to a method for generating electricity, heat and hydrogen or methanol by a coordinated operation of different types of power plants and corresponding additional equipment in a new, spatially related overall power plant complex. The primary energy sources are fossil fuels (mainly brown and hard coal and biogenic fuel) and Nuclear fuels are used.

Es ist Stand der Technik, hocheffektive Kraftwerke zur Versorgung mit Strom und Wärme zu betreiben, die mit fossilen Brennstoffen und/oder biogenen Brennstoffen und auch mit Kernenergie arbeiten. Diese Kraftwerke unterschiedlicher Größe haben einen hohen Entwicklungsstand erreicht, ermöglichen hohe Wirkungsgrade und arbeiten zuverlässig. Kohle gilt gegenwärtig und auf Grund der großen weltweiten Vorräte auch in naher Zukunft als Hauptbrennstoff. Gleichzeitig verursacht die Kohle aber auch die höchsten spezifischen CO2-Emissionen. Um diese zu verringern wird eine Sequestierung des CO2 angestrebt. Dies ist mit zusätzlichen Kosten und Verschlechterung der energetischen Effizienz verbunden.It is state of the art to operate highly efficient power plants for the supply of electricity and heat that work with fossil fuels and / or biogenic fuels and also with nuclear energy. These power plants of different sizes have reached a high level of development, enable high efficiencies and work reliably. Coal is currently considered as the main fuel in the near future due to large global supplies. At the same time, coal also causes the highest specific CO 2 emissions. In order to reduce this, a sequestration of the CO 2 is sought. This is associated with additional costs and degradation of energy efficiency.

Neben Verbrennungsanlagen- wird auch Vergasungsanlagen eine größere Bedeutung beigemessen. Diese Anlagen sind gegenüber Verbrennungsanlagen wesentlich komplexer und damit teurer und auch störanfälliger, ermöglichen aber eine einfachere CO2-Abtrennung, die Erzeugung von Wasserstoff und u. U. auch eine höher energetische Effizienz. Eine mögliche Variante ist in der DE 19802660 beschrieben. Eine Übersicht gibt Tabelle 1: Braunkohlekraftwerke der neuen Generation. Über die Perspektiven einer kohlebasierten Kraftwerkstechnologie gibt die Firma Siemens im November 2006 in der Schrift „VIK – Energietechnische Zukunftskonzepte" eine Übersicht.In addition to incineration plants, gasification plants are also given greater importance. These plants are compared to incinerators much more complex and therefore more expensive and more susceptible to interference, but allow for easier CO 2 separation, the generation of hydrogen and u. U. also a higher energy efficiency. One possible variant is in the DE 19802660 described. An overview is given in Table 1: Lignite-fired power plants of the new generation. In November 2006, Siemens presented an overview of the prospects of coal-based power plant technology in the publication "VIK - Energietechnische Zukunftskonzepte".

Ein weiterer Trend bei Verbrennungsanlagen ist der Einsatz von technischen Sauerstoff für die Verbrennung. Dadurch vereinfacht sich die CO2-Abtrennung beträchtlich und ausserdem verringern sich die Abgasverluste. Die Sauerstofferzeugung benötigt jedoch zusätzliche finanzielle und energetische Aufwendungen.Another trend in incinerators is the use of technical oxygen for combustion. As a result, the CO 2 separation considerably simplified and also reduce the exhaust gas losses. Oxygen production, however, requires additional financial and energy expenses.

Es ist weiterhin bekannt, Strom und Wärme in Kernkraftwerken zu erzeugen. Der Sicherheitsstandard ist sehr hoch. Die Energieumwandlung erfolgt CO2-frei.It is also known to generate electricity and heat in nuclear power plants. The security standard is very high. The energy conversion is CO 2 -free.

Der einzige inhärent sichere Kernkraftwerkstyp ist die Ausführung mit Hochtemperaturreaktor (HTR). In der üblichen Ausführung als modularer Hochtemperaturreaktor (MHTR), ist er den anderen Reaktortypen nicht nur hinsichtlich Sicherheit sondern auch in der energetischen Effizienz entscheidend überlegen.Of the only inherently safe nuclear power plant type is the execution with high temperature reactor (HTR). In the usual version as a modular high-temperature reactor (MHTR), it is the other types of reactors not only in terms of safety but also in the energetic Decisively superior in efficiency.

Die bekannten Kraftwerkstypen haben jeder für sich Vorteile und Nachteile. Ein Nachteil der Dampfkraftwerke, die mit fossilen oder biogenen Brennstoffen arbeiten, besteht in der Verschlechterung der Energieeffizienz bei CO2 Sequestierung und für den Fall der konzentrierten Sauerstoffzufuhr in der Notwendigkeit, diesen bereitzustellen, was entweder durch Antransport oder durch vorgeschaltete Luftzerlegung möglich ist und auch praktiziert wird.The known power plant types each have advantages and disadvantages. A disadvantage of the steam power plants operating with fossil or biogenic fuels is the deterioration of the energy efficiency in CO 2 sequestration and in the case of concentrated oxygen supply in the need to provide this, which is possible and practiced either by on-delivery or by upstream air separation becomes.

Der Nachteil eines Kernkraftwerkes ist darin zu sehen, dass bei der Erzeugung von Wasserstoff, welcher industriell stark nachgefragt wird und dessen Produktion in Zukunft CO2-frei und preisgünstig abzusichern und zu steigern ist, eine erhebliche Menge Sauerstoff entsteht. Für diese Menge Sauerstoff ist vor Ort eine vernünftige Verwendung noch nicht sichtbar.The disadvantage of a nuclear power plant is the fact that in the production of hydrogen, which is industrially highly demanded and whose production in the future CO 2 -free and cheap to secure and increase, a significant amount of oxygen is produced. For this amount of oxygen a reasonable use is not visible on site.

Dampfkraftwerke auf fossiler Basis sind hocheffektive, technisch bewährte Anlagen. Die Umwelt bedingte notwendige weitere Reduzierung des CO2-Ausstosses durch CO2-Abtrennung aus den Rauchgasen verursacht einen hohen Kosten- und Energieaufwand. Dieser wird reduziert mit dem Übergang zu Verbrennung mit Sauerstoff (Oxyfuel-Anlage) verringert.Fossil-based steam power plants are highly effective, technically proven systems. The environmental condition necessary further reduction of CO 2 emissions by CO 2 separation from the flue gases causes a high cost and energy expenditure. This is reduced with the transition to combustion with oxygen (oxyfuel plant) reduced.

Die dazu erforderliche Luftzerlegungsanlage ist allerdings auch energieaufwendig und ein Fremdkörper im Kraftwerk.The However, this required air separation plant is also energy consuming and a foreign body in the power plant.

Sauerstoff, der bei der Elektrolyse z. B. mit CO2-freien MHTR-Strom als Nebenprodukt anfällt, ist ein gefährliches Industriegas, dessen Transport oder Entsorgung Probleme bereitet.Oxygen, the z. B. with CO 2 -free MHTR-electricity as by-product, is a dangerous industrial gas, the transport or disposal causes problems.

Die Erfindung hat das Ziel, die Ökonomie und die Ökologie des mit fossilen oder auch biogenen Brennstoffen arbeitenden Kraftwerkes deutlich zu verbessern. Es soll die Chance genutzt werden, anfallenden Wasserstoff weiter zu verarbeiten, unter anderen zu gefragten Energieträgern. Bei der Herstellung von Methanol würde das anfallende CO2 gleich genutzt werden können, wodurch zusätzliche Synergieeffekte entstehen.The invention aims to significantly improve the economy and ecology of the fossil or biogenic power plant. It should be used the opportunity to process accumulating hydrogen, among other sought-after sources of energy. In the production of methanol, the resulting CO 2 could be used immediately, creating additional synergy effects.

Die Erfindung hat die Aufgabe, die Energiebilanz des mit fossilen oder biogenen arbeitenden Kraftwerkes wesentlich zu verbessern und die Schwachstellen seines Betriebes zu überwinden. Es ist weiterhin die Aufgabe gestellt, den Betrieb in technisch einfacher Weise effektiv zu gestalten.The Invention has the task of the energy balance of fossil or biogenic working power plant to improve significantly and the weak points to overcome his business. It is still the task made to make the operation in a technically simple manner effectively.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein Hybridkraftwerk geschaffen wird, das aus zwei an sich bekannten Komponenten besteht, die miteinander in neuer und erfinderischer Weise gekoppelt werden. Es wird ein Oxyfuel-Dampfkraftwerk mit CO2-Abtrennung vorgeschlagen, das entsprechend 1 arbeitet. Dieses wird gekoppelt mit einem MHTR-Kraftwerk, wie es in 2 dargestellt ist. Das MHTR-Kraftwerk besteht aus inhärent sicheren HTR-Modulen, das sind Hochtemperaturreaktoren oder auch Kugelbettofen genannt. Die HTR-Module sind nicht nur inhärent und proliferationssicher sowie relativ unproblematisch in der Entsorgung des Kernbrennstoffs, sondern ermöglichen auch hohe thermodynamische Wirkungsgrade und die Auskopplung von Hochtemperatur-Wärme.The object is achieved in that a hybrid power plant is created, the consists of two components known per se, which are coupled together in a new and inventive way. An oxyfuel steam power plant with CO 2 separation is proposed accordingly 1 is working. This will be coupled with a MHTR power plant, as in 2 is shown. The MHTR power plant consists of inherently safe HTR modules, which are called high-temperature reactors or ball-bed type furnaces. The HTR modules are not only inherent and proliferation safe and relatively unproblematic in the disposal of nuclear fuel, but also allow high thermodynamic efficiencies and the extraction of high-temperature heat.

Die Koppelstellen der beiden Teilkraftwerke sind die bisherigen, durch die Erfindung überwundenen Schwachstellen der beiden Einzelkraftwerke. Das ist zum ersten die Sauerstoffbereitstellung für den Oxyfuel-Prozess durch die Druckwasser- bzw. Heißdampf-Elektrolyse, die mit Strom und Wärme vom MHTR-Teil versorgt wird und zum anderen die dampfseitige Kopplung des MHTR-Prozesses mit dem Oxyfuel-Dampfkraftwerk. Während das Ausgangskraftwerk aufgrund des Oxyfuel-Prozesses, der fortschrittlichen thermodynamischen Gesamtauslegung und der Brennstoffvorbehandlung auch mit CO2-Aushaltung hohe Wirkungsgrade erreicht, wird dies bei dem Hybridkraftwerk durch Synergieeffekte noch weiter verbessert.The coupling points of the two power plants are the previous, overcome by the invention vulnerabilities of the two individual power plants. Firstly, the oxygen supply for the oxyfuel process by the pressurized water or hot steam electrolysis, which is supplied with power and heat from the MHTR part and on the other hand, the steam-side coupling of the MHTR process with the oxyfuel steam power plant. While the output power plant achieves high efficiencies due to the oxyfuel process, the advanced overall thermodynamic design, and the fuel pretreatment, even with CO 2 exhaustion, the hybrid power plant will be further enhanced by synergy effects.

Diese Synergieeffekte sind:

  • – effiziente Sauerstoffbereitstellung durch Druckwasser- bzw. Heißdampfelektrolyse
  • – die Elektrolyse stellt als gewünschtes Hauptprodukt den industriell begehrten reinen Wasserstoff her, welcher in einem Herstellungsverfahren ohne die Bildung von CO2 entsteht und verwendet werden kann z. B. als
  • – Kraftstoff für Brennstoffzellen
  • – Kraftstoff für Motore und
  • – zur Weiterverarbeitung zu Flüssigkraftstoffen (z. B. Methanol).
  • – Reduzierung des Dampfkraftprozesses des MHTR auf den Abhitzekessel; der Dampf des Abhitzekessels wird in der Großturbinenanlage des Oxyfuel-Dampfkraftwerkes verstromt
  • – Verbesserung der CO2-Bilanz und der Effizienz des Gesamtkraftwerkes.
These synergy effects are:
  • - efficient oxygen supply by pressurized water or superheated steam electrolysis
  • - The electrolysis is the desired main product of the industrially sought pure hydrogen, which is produced in a production process without the formation of CO 2 and can be used for. B. as
  • - Fuel for fuel cells
  • - Fuel for engines and
  • - for further processing into liquid fuels (eg methanol).
  • - Reduction of the steam power process of the MHTR on the waste heat boiler; the steam of the waste heat boiler is converted into electricity in the large-scale turbine plant of the oxyfuel steam power plant
  • - Improvement of the CO 2 balance and the efficiency of the entire power plant.

Die Kopplung der beiden Kraftwerksteile wird an Hand einer 2 näher erläutert.The coupling of the two power plant parts is on hand 2 explained in more detail.

Die Einkopplung zusätzlicher Wärme in die Dampfturbinenanlage 4 des Oxyfuel-Dampfkraftwerkes aus der Abhitzekesselanlage 8 des MHTR-Kraftwerkes erfolgt technisch in der Art und Weise, dass die Dampfeinleitung z. B. an geeigneter Stelle in den MD-Teil der Hauptdampfturbine zugeführt wird. Die Anpassung der Dampftemperaturen kann z. B. durch eine Wasser-Einspritzregelung erfolgen.The coupling of additional heat into the steam turbine plant 4 of the oxyfuel steam power plant from the waste heat boiler plant 8th the MHTR power plant is technically in the way that the steam inlet z. B. is supplied at a suitable location in the MD part of the main steam turbine. The adaptation of the steam temperatures can z. B. by a water injection control.

Die Sauerstoffzufuhr in die Dampfkesselanlage 3 des Oxyfuel-Kraftwerkes aus der Elektrolyse erfolgt über einen Zwischenspeicher und über Dosier- und Mischeinrichtungen.The oxygen supply to the steam boiler system 3 of the oxyfuel power plant from the electrolysis takes place via a buffer and dosing and mixing devices.

Die Kopplung der beiden Teilkraftwerke bringt viele Vorteile. Ein neuer, zukunftsträchtiger Grundstoff, der Wasserstoff wird durch Hochdruck-Wasser- oder Hochtemperatur-Wasserdampf-Elektrolyse in CO2-freier Herstellungsart und preisgünstig zur Verfügung gestellt, wobei gleichzeitig der anfallende Sauerstoff ohne Transport sinnvoll verwendet wird.The coupling of the two power plants brings many advantages. A new, promising raw material, the hydrogen is made available by high-pressure water or high-temperature water vapor electrolysis in CO 2 -free production and low cost, at the same time the resulting oxygen is used without transport meaningful.

Der gesamte Prozess des Hybridkraftwerkes ist ausnehmend umweltfreundlich und doch hoch energieeffizient. Im MHTR-Kraftwerk wird die Dampfturbine eingespart, weil der Dampf des Abhitzekessels direkt der Dampfturbine des Oxyfuel.Kraftwerkes zugeführt wird.Of the entire process of the hybrid power plant is exceptionally environmentally friendly yet highly energy efficient. In the MHTR power plant, the steam turbine saved, because the steam of the waste heat boiler directly to the steam turbine the Oxyfuel.Kraftwerkes is supplied.

Ein weiterer Vorteil besteht darin, dass der anfallende Wasserstoff mit dem im Verbrennungsprozess anfallenden CO2 direkt zu Methanol weiter verarbeitet werden kann.Another advantage is that the resulting hydrogen can be further processed directly to methanol with the obtained in the combustion process CO 2 .
