Description
Die Erfindung betrifft eine Anordnung für die optische Bestimmung der Konzentration von Alkalien in einem Heißgasstrom.The invention relates to an arrangement for the optical determination of the concentration of alkalis in a hot gas stream.
Bei der Erzeugung von Heißgas durch Verbrennen oder Verga sen von Kohle in einer druckaufgeladenen Wirbelschichtfeue rung für den Betrieb einer Gasturbine sind die freigeworde nen dampfförmigen Alkaliverbindungen für die Korrosion an den Turbinenschaufeln verantwortlich. Es ist deshalb uner läßlich, Alkalien im Heißgas zu bestimmen, um erforderliche Maßnahmen zur Vermeidung von Korrosionen einzuleiten. Die Bestimmung von Gaskomponenten im Heißgasstrom erfolgt direkt durch einen Teilstrom in einer Meßstrecke (z. B. DD 57 220, DD 291 399 A5) oder direkt durch einen Teilstrom über eine Absorptionslösung nach verschiedenen Analysenverfahren (z. B. DD 269 448 A1).When generating hot gas by burning or gasification coal in a pressurized fluidized bed fire For the operation of a gas turbine, these have been freed up vaporous alkali compounds for corrosion responsible for the turbine blades. It is therefore unimportant casual to determine alkalis in hot gas to required Take measures to avoid corrosion. The Gas components in the hot gas flow are determined directly due to a partial flow in a measuring section (e.g. DD 57 220, DD 291 399 A5) or directly through a partial flow via a Absorption solution according to various analytical methods (e.g. DD 269 448 A1).
Bei Heißgas-Temperaturen größer 1100°C werden die Alkalia tome thermisch angeregt, so daß ein Licht definierter Wel lenlänge emittiert wird (DE 42 32 771 A1). Diese Emissionen werden über Faseroptiken oder Fenster nach ihrer Intensität ausgewertet.At hot gas temperatures greater than 1100 ° C, the alkalis tome thermally excited so that a light defined Wel len length is emitted (DE 42 32 771 A1). These emissions are over fiber optics or windows according to their intensity evaluated.
Bekannt ist es, nach EP 0 192 919 A1 bei einer Temperatur des Heißgasstromes von über 1000°C mit einer thermischen Anregestrecke (Funkenstrecke) und einer optischen Erfas sungseinrichtung Bestandteile des Heißgasstromes zu bestim men. Hierfür ist es notwendig, ein Probengas aus dem Heiß gasstrom zu entnehmen und die Untersuchung außerhalb des Heißgasstromes durchzuführen, was als Nachteil angesehen wird.It is known, according to EP 0 192 919 A1, at one temperature of the hot gas flow of over 1000 ° C with a thermal Excitation path (spark gap) and an optical detection to determine components of the hot gas flow men. For this it is necessary to get a sample gas from the hot gas flow and the investigation outside the Perform hot gas flow, which is considered a disadvantage becomes.
Weiterhin sind Vorrichtungen bekannt, die ebenfalls außer halb des Heißgasstromes angeordnet sind und verschiedene weitere Anregungsarten aufweisen (DE-OS 15 98 303, GB 900 423).Devices are also known which are also except are arranged half of the hot gas flow and different have further types of excitation (DE-OS 15 98 303, GB 900 423).
Bei Heißgas-Temperaturen kleiner 1000°C ist eine solche op tische Erfassung nicht möglich, da keine Emission der Al kaliatome aufgrund der geringen thermischen Anregungen ein tritt.At hot gas temperatures below 1000 ° C, such an op Table recording not possible because no emission of the Al kaliatome due to the low thermal excitation occurs.
Es ist daher bekannt, mit einem leistungsstarken Laser im UV-Bereich die dampfförmigen Alkaliverbindungen aufzuspal ten und anzuregen. Durch ein Fenster wird der Laserstrahl eingespeist und am gegenüberliegenden Fenster ein Sekundär elektronenvervielfacher zur Erfassung der Laserenergie an geordnet. Im Winkel von 90° ist ein zweiter Sekundärelek tronenvervielfacher zur Erfassung des emittierten Lichts angeordnet.It is therefore known to use a powerful laser in the UV range to split the vaporous alkali compounds and stimulate. The laser beam is through a window fed in and a secondary at the opposite window electron multiplier for recording the laser energy orderly. A second secondary electrode is at an angle of 90 ° trone multiplier for recording the emitted light arranged.
Es wurde jedoch festgestellt, daß zwar Alkaliverbindungen Na2O, NaCl, K2O und KCl aufgespalten und angeregt werden, nicht jedoch die im Heißgas ebenfalls vorhandenen Alkali verbindungen Na2SO4 und K2SO4. Dadurch sind nicht alle die Korrosionen auslösenden Alkalien erfaßbar. However, it was found that although alkali compounds Na 2 O, NaCl, K 2 O and KCl are broken down and excited, the alkali compounds Na 2 SO 4 and K 2 SO 4 which are also present in the hot gas are not. As a result, not all the alkalis that trigger the corrosion can be detected.
Aufgrund der weiteren Inhaltsstoffe des Heißgases wird durch Absorption die Leistung des UV-Lasers stark redu ziert, so daß reale Meßergebnisse nur über komplizierte Be rechnungsverfahren erreichbar sind. Um die genannten Alka liverbindungen trotzdem zu erfassen, sind erhebliche Auf wendungen für die Einkopplung einer großen Anregungsenergie durch einen UV-Laser erforderlich. Darüber hinaus ist die Regelbarkeit nur mit erheblichen weiteren Aufwendungen mög lich, um eine Anpassung an spezifische Analysenaufgaben zu erreichen.Due to the other ingredients of the hot gas the absorption of the UV laser is greatly reduced by absorption adorns, so that real measurement results only over complicated Be calculation methods are achievable. To the mentioned Alka Capturing liver bindings anyway is a significant task applications for the coupling of a large excitation energy required by a UV laser. In addition, the Controllability only possible with considerable additional expenses to adapt to specific analysis tasks to reach.
Außerdem ist es bekannt, aus dem Heißgasstrom kleiner 1000°C einen Probengasstrom zu entnehmen, mittels einer Acetylen-Sauerstoff-Flamme, einen Plasmabrenner (DD 284 528 A5) oder einen Gleichstrom-Lichtbogen (DD 200 351) die Al kaliverbindungen aufzuspalten und die Alkaliatome zur Licht emission anzuregen. Das emittierte Licht spezieller Wel lenlänge wird mit optischen Mitteln erfaßt und ausgewertet.It is also known to be smaller from the hot gas flow 1000 ° C to take a sample gas stream, using a Acetylene-oxygen flame, a plasma torch (DD 284 528 A5) or a direct current arc (DD 200 351) the Al split potassium compounds and the alkali atoms to light to stimulate emission. The light emitted by special worlds lenlength is recorded and evaluated using optical means.
Diese Methoden weisen jedoch folgende Nachteile auf:
However, these methods have the following disadvantages:
- - Es sind geeignete Probeentnahmeeinrichtungen und Probe leitungen erforderlich.- There are suitable sampling devices and samples lines required.
- - Es treten Ablagerungen bzw. Kondensation der zu bestim menden Bestandteile auf.- Deposits or condensation occur components.
Weiterhin ist bekannt, innerhalb des Heißgasstromes einen mit einem gasförmigen Brennstoff betriebenen Brenner anzu ordnen und durch die erzeugte Flamme die Alkaliverbindun gen zur Lichtemission anzuregen.It is also known to have a within the hot gas stream to run with a gaseous fuel burner arrange and by the flame generated the alkali compound to stimulate light emission.
Obwohl eine Reihe von Vorteilen erreichbar sind, weist die
se Lösung noch folgende Nachteile auf:
Although a number of advantages can be achieved, this solution still has the following disadvantages:
- - Eintrag zusätzlicher Brenngase- Entry of additional fuel gases
- - Erzeugung einer offenen Flamme - Generation of an open flame
- - Bei Laständerungen werden Flammenstörungen erzeugt, die zu Schwankungen des Meßsignals und damit zu Auswertefeh lern führen.- Flame disturbances are generated when the load changes to fluctuations in the measurement signal and thus to evaluation errors learn to lead.
- - Besonderer Aufwand an Brenngas und Anlagentechnik- Special expenditure on fuel gas and plant technology
- - Aufgrund von Laständerungen ist eine Regelbarkeit nicht gewährleistet, so daß spezifische Analysenaufgaben nicht ohne weiteres durchführbar sind.- Due to changes in load is controllable not guaranteed, so specific analysis tasks are not easily feasible.
Aus den genannten Gründen wird die Bestimmung der Alkali verbindungen immer wieder über Probenahmesysteme realisiert und die bekannten Nachteile in Kauf genommen.For the reasons mentioned, the determination of the alkali connections realized over and over again via sampling systems and accepted the known disadvantages.
Der Erfindung liegt daher die Aufgabe zugrunde, die Emissi on der Alkaliverbindungen direkt im Heißgas kleiner 1000°C zu erreichen, ohne daß Laständerungen zu Verfälschungen führen. Außerdem soll eine Regelbarkeit entsprechend der Analysenaufgaben gewährleistet sein.The invention is therefore based on the task, the Emissi on the alkali compounds directly in the hot gas below 1000 ° C to achieve without changes in load to falsifications to lead. In addition, a controllability according to the Analytical tasks can be guaranteed.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß durch eine Anordnung für die opti sche Bestimmung der Konzentration von Alkalien in einem Heißgasstrom mit einer Temperatur unter, 1000°C in einem Heißgaskanal vor einer Gasturbine, bei der als thermische Anregungs strecke zur Erzeugung einer Lichtemission der Alkalien eine Hochfrequenz-Induktionsspule oder eine Lichtbogen- Elektrodenstrecke direkt in den Heißgaskanal eingesetzt und eine optische Erfassungsanordnung für die Auskopplung der emittierten Lichtstrahlen vorgesehen ist.This object is achieved according to the invention by an arrangement for the opti determination of the concentration of alkalis in a hot gas stream a temperature below. 1000 ° C in a hot gas duct a gas turbine used as a thermal excitation stretch to produce light emission from the alkalis High frequency induction coil or an arc Electrode section inserted directly into the hot gas duct and an optical detection arrangement for decoupling the emitted light rays is provided.
Dadurch wird erreicht, daß die Alkaliverbindungen aufge spalten, die Alkaliatome direkt emittieren und diese Emis sionen optisch erfaßt werden.This ensures that the alkali compounds open cleave, emit the alkali atoms directly and these emis Sions are optically detected.

The optical fiber optic 10 is integrated into the hot gas duct 1 as an optical detection arrangement.
Es ist ohne weiteres möglich, die thermische Anregungsstrecke (2; 7, 8) zusammen mit der optischen Erfassungs-Anordnung (4; 10) als ein Bauteil in den Heißgaskanal 1 einzusetzen.It is easily possible to use the thermal excitation path ( 2 ; 7 , 8 ) together with the optical detection arrangement ( 4 ; 10 ) as a component in the hot gas duct 1 .
Im Heißgaskanal 1 wird das von der druckaufgeladenen Wir belschichtfeuerung erzeugte Heißgas zur Gasturbine trans portiert.In hot gas duct 1 , the hot gas generated by the pressure-charged fluidized bed combustion is transported to the gas turbine.
