"Anlage und Einrichtung zur energetischen Nutzung von Biomasse in Energiewandlungsanlagen mit Kraft-Wärme-Kopplung""Plant and equipment for the energetic use of biomass in energy conversion plants with combined heat and power"
Die Anlage und die Einrichtung zur energetischen Nutzung von Biomasse in Energiewandlungsanlagen mit Kraft-Wärme-Kopplung kann in thermischen Energiewandlungsanlagen angewendet werden, in denen Biomasse als Primärenergieträger zum Einsatz kommen und die Nutzenergie Wärme und Elektroenergie gleichzeitig als Prozeßgrößen ausgekoppelt und bedarfsstrukturgerecht den Verbrauchern bereitgestellt werden sollen. Dieses Prinzip der Kraft-Wärme-Kopplung bildet die Basis für Heizkraftwerke zentraler und dezentraler Einrichtungen.The system and the equipment for the energetic use of biomass in energy conversion plants with combined heat and power can be used in thermal energy conversion plants in which biomass is used as a primary energy source and the useful energy heat and electrical energy are simultaneously extracted as process variables and made available to consumers in accordance with demand. This principle of combined heat and power forms the basis for cogeneration plants in central and decentralized facilities.
Gas- und Dampfturbinen-Heizkraftwerke, bestehend aus Hauptkomponenten Gasturbine, Abhitzekessel und Dampfturbine, stellen für die fossilen Brennstoffe Erdgas und Heizöl Stand der Technik dar. Die technische Realisierung der Kraft-Wärme-Kopplung als Heiz-Kraftanlage ist gegenüber der getrennten Erzeugung von Elektroenergie und Wärme durch den thermodynamisch begründeten, höchstens Gesamtwirkungsgrad und so wirtschaftliche Effizienz gekennzeichnet.Gas and steam turbine combined heat and power plants, consisting of the main components gas turbine, waste heat boiler and steam turbine, represent the state of the art for the fossil fuels natural gas and heating oil. The technical implementation of combined heat and power as a combined heat and power plant is characterized by the thermodynamically based, maximum overall efficiency and thus economic efficiency compared to the separate generation of electrical energy and heat.

Einen weiteren Vorteil des Gas- und Dampfturbinen-Prozesses stellt die Möglichkeit dar, mit einer Entnahme-Kondensations-Dampfturbine die Gesamtanlage unabhängig von Wärmebedarfsschwankungen mit Auslegungsleistung und somit ohne teillastbedingte Wirkungsgradminderung betreiben zu können.A further advantage of the gas and steam turbine process is the possibility of using an extraction condensing steam turbine to operate the entire plant at design output regardless of fluctuations in heat demand and thus without any reduction in efficiency due to part load.
Gas- und Dampfturbinen-Heizkraftwerke sind durch die thermische und hydraulische Belastung der Gasturbinenbrennkammer in ihrer Leistung nach oben hin konstruktiv begrenzt. Eine untere Grenze resultiert aus der noch ausführbaren Beschaufelung der Dampfturbine sowie aus der durch relativ hohe Investkosten stark beeinflußten Wirtschaftlichkeit. The design limits the output of gas and steam turbine heating power plants due to the thermal and hydraulic load on the gas turbine combustion chamber. A lower limit results from the blading of the steam turbine that can still be carried out and from the economic efficiency, which is strongly influenced by the relatively high investment costs.
Voraussetzung für die energetische Nutzung von Biomasse zum Antrieb von Gasturbinen und Gasmotoren ist die Erzeugung eines Brenngases. Für die Vergasung von Biomasse, vorrangig Holz, existieren verschiedene Verfahren, von denen u.a. die Festbettvergasung im Gleich- oder Gegenstrom und die Wirbelschichtvergasung (jeweils atmosphärisch oder durckaufgeladen) für den Antrieb einer Energiewandlungsmaschine geeignet erscheinen. Es wurden Blockheizkraftwerke mit Gasmotor auf Holzgas- und folglich Schwachgasbasis konzipiert, apparatetechnisch angepaßt und erprobt. Der direkte Kontakt des schadstoffbeladenen Verbrennungsgases und des Schmierungssystems im Motor sowie eine Teilkondensation von Kohlenwasserstoffen durch die thermodynamisch bedingte Mantelkühlung sind Ursachen für nur geringe Standzeiten dieser Anlagen. Darüber hinaus gestatten die Mantelkühlung und die Abgasenthalpienutzung keine nachgeschaltete Dampferzeugung und Dampfturbine, so daß Wärmebedarfsschwankungen immer eine Teillastfahrweise zur Folge haben.The prerequisite for the energetic use of biomass to drive gas turbines and gas engines is the production of a fuel gas. There are various processes for the gasification of biomass, primarily wood, of which fixed bed gasification in co-current or countercurrent and fluidized bed gasification (both atmospherically or supercharged) appear suitable for driving an energy conversion machine. Combined heat and power plants with gas engines based on wood gas and therefore lean gas have been designed, adapted and tested. The direct contact of the pollutant-laden combustion gas and the lubrication system in the engine as well as partial condensation of hydrocarbons due to the thermodynamic jacket cooling are the reasons why these systems only have a short downtime. In addition, the jacket cooling and the use of exhaust gas enthalpy do not allow for downstream steam generation and steam turbine, so that fluctuations in heat demand always result in partial load operation.
Die technische Realisierung eines Gas- und Dampfturbinen-Heizkraftwerkes auf der Basis niederkalorischer Biomassegases setzt folgende Konzeption voraus:The technical realisation of a gas and steam turbine cogeneration plant based on low-calorific biomass gas requires the following concept:
• Biomassevergasung mit definierter Brennstoffstruktur und Rohgasreinigung• Biomass gasification with defined fuel structure and raw gas purification
• Gasturbine mit an Schwachgas angepaßter Brennkammer• Gas turbine with combustion chamber adapted to lean gas
• Abhitzedampferzeuger mit oder ohne Zusatzfeuerung• Heat recovery steam generator with or without additional firing
• Dampfturbine mit energetisch sinnvoller Ausführung als Entnahme-Kondensationsturbine • Steam turbine with energetically sensible design as extraction condensing turbine
Der Einsatz von Abhitzedampferzeugern mit gespeister Dampfturbine gehören zum Stand der Technik.The use of heat recovery steam generators with fed steam turbines is state of the art.
Die Kombination von Biomassevergasung und Gasturbinentechnik scheiterte bisher hauptsächlich an der Qualität des im Vergaser erzeugten Brenngases und einer stabilen Verbrennung des niederkalorischen Brenngases in der Brennkammer der Gasturbine. The combination of biomass gasification and gas turbine technology has so far failed mainly due to the quality of the fuel gas produced in the gasifier and the stable combustion of the low-calorific fuel gas in the combustion chamber of the gas turbine.
Der Einsatz einer Gasturbine setzt teerfreies Brenngas geringer Staubbeladung voraus, hohe Brenngasvolumenströme infolge des geringen Heizwertes erfordern vergrößerte Brennkammern der Gasturbinen, dem jedoch ein verringertes Luftverhältnis entgegensteht. The use of a gas turbine requires tar-free fuel gas with a low dust load; high fuel gas volume flows due to the low calorific value require larger combustion chambers in the gas turbines, which, however, is counteracted by a reduced air ratio.
Daraus resultiert die Forderung nach einer thermodynamisch, hydrodynamisch und stofflich exakt definierten Schnittstelle zwischen Gaserzeugung einschließlich Gasreinigung und Brennkammereintritt der Gasturbine. Die damit festzulegende Koppelparameter sind Voraussetzung für die Gas- und Dampfturbinenanlage.This results in the requirement for a thermodynamically, hydrodynamically and materially precisely defined interface between gas generation including gas cleaning and the combustion chamber inlet of the gas turbine. The coupling parameters to be defined in this way are a prerequisite for the gas and steam turbine plant.
Resultierend aus den Mängeln des Technikstandes besteht das Ziel in der Anordnung einer apparativen Ausrüstung für den Gasturbinen- und/oder Gas-Dampfturbinenprozeß mit Biomassegas als Schwachgas, die die strömungsmechanischen, thermodynamischen und stofflichen Bedingungen für diesen Prozeßablauf erfüllt.As a result of the deficiencies in the current state of technology, the aim is to arrange an apparatus for the gas turbine and/or gas-steam turbine process with biomass gas as a lean gas, which fulfils the fluid mechanical, thermodynamic and material conditions for this process sequence.
Die Lösung dieser Aufgabe besteht daher im Eliminieren der negativen Einflußgrößen, wie niedriger Heizwert und so niedrige Temperatur der Wärmezufuhr im Joule-Prozeß sowie schadstoffbelasteten Brenn- und Verbrennungsgas bis zum Eintritt in den Entspannungsteil der Gasturbine, wodurch der technisch stabile Ablauf des thermodynamischen Kreisprozesses mit Gasturbinen und energetisch effizienter Kraft-Wärme-Kopplung garantiert ist.The solution to this problem therefore consists in eliminating the negative influencing factors, such as low calorific value and low temperature of the heat supply in the Joule process as well as polluted fuel and combustion gas up to the entry into the expansion part of the gas turbine, which guarantees the technically stable course of the thermodynamic cycle with gas turbines and energetically efficient combined heat and power.
Erfindungsgemäß wird das Ziel dadurch erreicht, daß das mit bekannten Biomassevergasungsverfahren erzeugte Brenngas nach chemischer und physikalischer Reinigung nicht direkt zur Verbrennung und Wärmeabgabe der Gasturbinenbrennkammer zugeleitet, sondern einer von der Gasturbine apparativ getrennten und so externen Brennkammer zugeführt wird. Dieser ist ein Oberflächenwärmeübertrager nachgeschaltet, in dem die Wärmezufuhr bei stofflicher Trennung an das sekundärseitig geführte Heißluftturbinenmedium erfolgt. Der Abluftkanal der Heißluftturbine ist sowohl direkt mit der externen Brennkammer zum Zwecke der Nutzung vorgewärmter Verbrennungsluftzufuhr, als auch mit der abgasführenden Leitung nach dem Oberflächenwärmeübertrager zur Stützung der Dampferzeugung in einem Abhitzedampferzeuger und den Betrieb einer nachgeschalteten Dampfturbine verbunden.According to the invention, the aim is achieved in that the fuel gas produced using known biomass gasification processes is not fed directly to the gas turbine combustion chamber for combustion and heat release after chemical and physical purification, but is fed to a combustion chamber that is separated from the gas turbine and is thus external. This is followed by a surface heat exchanger in which the heat is supplied to the hot air turbine medium on the secondary side with material separation. The exhaust air duct of the hot air turbine is connected both directly to the external combustion chamber for the purpose of using preheated combustion air supply and to the exhaust gas line after the surface heat exchanger to support steam generation in a waste heat steam generator and the operation of a downstream steam turbine.
Darüber hinaus besteht eine Verbindung zwischen abgasführender Leitung nach dem Oberflächenwärmeübertrager und der externen Brennkammer.In addition, there is a connection between the exhaust gas line after the surface heat exchanger and the external combustion chamber.
Vorteile der Anlage und EinrichtungAdvantages of the system and facility
• Wegfall einer konstruktiven und auslegungstechnischen Brennkammeranpassung herkömmlicher Gasturbinen, da die Gasturbineneintrittstemperatur unabhängig vom• Elimination of structural and design-related combustion chamber adjustments of conventional gas turbines, since the gas turbine inlet temperature is independent of the
Heizwert des Brenngases über das Temperaturniveau im Oberflächenwärmeübertrager bestimmt wird. Dadurch entfällt auch der damit verbundene zusätzliche Luftstrom zur Brennkammerkühlung und die Vergrößerung der aufzuwendenden Antriebsleistung des Luftverdichters.The calorific value of the fuel gas is determined by the temperature level in the surface heat exchanger. This also eliminates the associated additional air flow for combustion chamber cooling and the increase in the drive power required for the air compressor.
Einsparung eines Brenngasverdichters zur Erzeugung des erforderlichen Gasturbineneintrittsdruckes sowie Reduzierung der energie- und kostenaufwendigen Brenngasreinigung, da die stoffliche Trennung zum Gasturbinenmedium erfolgt.Saving of a fuel gas compressor to generate the required gas turbine inlet pressure as well as reduction of the energy- and cost-intensive fuel gas cleaning, since the material separation from the gas turbine medium takes place.
Die Verwendung der Gasturbinenabluft einerseits als Verbrennungsluft und andererseits als Heizmedium bei der Abwärmenutzung im Abhitzekessel kompensiert den negativen Einfluß niedrigen Heizwertes des Brenngases und erhöht den thermodynamischen Wirkungsgrad der Kraft-Wärme-Kopplung.The use of gas turbine exhaust air on the one hand as combustion air and on the other hand as a heating medium for waste heat utilization in the waste heat boiler compensates for the negative influence of the low calorific value of the fuel gas and increases the thermodynamic efficiency of the combined heat and power generation.
Die Kombination von Nutzung der Gasturbinenabluft zur Verbrennung und Beheizung des Abhitzekessels und Abgasrücksaugung in die externe Brennkammer ermöglicht außerdem die Regelung der Abkühlungsrate des Verbrennungsgases im Oberflächenwärmeübertrager, daß im Abhitzekessel Dampf hoher Temperatur erzeugt und eine nachgeschaltete Dampfturbine mit hohem Wirkungsgrad betrieben und ein effektiver energetischer Wirkungsgrad der Gesamtanlage bei Schwachgaseinsatz zwischen 50 bis 56 % erzielt werden kann.The combination of using the gas turbine exhaust air for combustion and heating of the waste heat boiler and exhaust gas recirculation into the external combustion chamber also enables the cooling rate of the combustion gas to be controlled in the surface heat exchanger, so that high temperature steam can be generated in the waste heat boiler and a downstream steam turbine can be operated with high efficiency, and an effective energy efficiency of the entire plant of between 50 and 56% can be achieved when using lean gas.
