    <title language="eng">Identification of wavelength regions for non-contact temperature measurement of combustion gases at high temperatures and high pressures</title>
    <abstract language="eng">Stationary gas turbines are still an important part of today's power supply. With increasing temperature of the hot combustion gas inside a gas turbine, the efficiency factor of the turbine increases. For this reason, it is intended to operate turbines at the highest possible gas temperature. Therefore, in the combustion chamber and especially at the position of the first stage guide vanes the gas temperature needs to be measured reliably. To determine the gas temperature, one promising approach is the application of a non-contact measurement method using a radiation thermometer. A radiation thermometer can measure the gas temperature remotely from outside of the harsh environment. At ZAE Bayern, a high temperature and high pressure gas cell has been developed for this purpose in order to investigate gases and gas mixtures under defined conditions at high pressures and high temperatures. This gas cell can …</abstract>

    <title language="deu">Berührungslose Temperaturmessung an Verbrennungsgasen bei hohen Temperaturen und hohen Drücken</title>
    <abstract language="deu">Stationäre Gasturbinen sind von großer Bedeutung für die heutige Energieversorgung. Der Wirkungsgrad einer Gasturbine steigt mit zunehmender Heißgastemperatur an. Turbinenhersteller bzw. Kraftwerksbetreiber sind daher bestrebt, Turbinen bei der höchsten materialtechnisch möglichen Heißgastemperatur einzusetzen. Eine entsprechende Prozessoptimierung des Turbinenbetriebs setzt somit die exakte Kenntnis der Gastemperaturen während des Betriebs und damit eine verlässliche Messung derselben voraus. Zur Messung der Gastemperatur werden derzeit in der Regel Thermoelemente unmittelbar im Abgasstrom platziert. Aufgrund der dort vorherrschenden extremen Bedingungen degradieren diese Sensoren allerdings sehr schnell. Ein alternativer Ansatz sieht die Entwicklung eines berührungslosen Messverfahrens auf der Grundlage von Strahlungsthermometern vor. Für die Umsetzung dieses Vorhabens ist die genaue Kenntnis des Verhaltens der infrarot-optischen Emissions- und Transmissionsspektren der im Abgasstrom enthaltenen Gase bei hohen Temperaturen und Drücken eine wesentliche Voraussetzung. Aus diesem Grund wurde am ZAE Bayern eine Hochtemperatur-Hochdruck-Gaszelle entwickelt, die es in Verbindung mit einem FTIR-Spektrometer erlaubt, Gase und Gasgemische hinsichtlich dieser Gesichtspunkte zu charakterisieren. In dieser Arbeit wird die neue Messapparatur vorgestellt und Gasgemische, die für die Turbinenanwendungen relevant sind, werden analysiert. Zur Identifizierung eines geeigneten Wellenlängenbereichs für die geplante berührungslose Temperaturmessung wurden erste Messungen durchgeführt, auf deren Grundlage ein adäquater Wellenlängenbereich ermittelt werden konnte.</abstract>

    <title language="eng">Phase change materials for use in thermally and electrically stressed insulation for high voltage applications</title>
    <abstract language="eng">The temperature of high voltage equipment is often the limiting factor when transmitting electrical energy because the electrical insulation can get severely aged when the temperature is exceeding a certain limit. Hence, cooling has to be improved or heat generation must be reduced to avoid damage of the insulation. In this paper a new method was examined by investigating electrically insulating phase change materials which are able to store latent heat during a phase change from the solid to liquid state in times of high energy demand. To verify the electrically insulating properties of paraffins, one class of phase change materials, a special test cell was designed allowing the determination of breakdown voltage of phase change materials. The measurements on one paraffin sample proved the promising electrical insulating properties and it was shown that the breakdown voltage in the liquid state is comparable …</abstract>

    <title language="eng">Infrared-optical characterization of emitting and absorbing gases at high temperatures and high pressures</title>
    <abstract language="eng">In the context of the optimization of stationary gas turbines, the surface temperatures of the turbine blades have to be measured by a non-contact technique using radiation thermometers during operation of the turbine. Nowadays turbine blades are protected by thermal barrier coatings. The infrared-optical properties of these coatings require the usage of the MIR or LWIR region for non-contact measurement of the surface temperatures. For performing such measurements and for properly analyzing the derived data, the transmission and absorption spectra of the combustion gas mixture within the turbine were determined at the local conditions during operation of the turbine. Therefore, subject of this work is the measurement of the transmission spectra of carbon dioxide and water vapor at high temperatures and high pressures to identify a wavelength range, which is almost free of absorption and emission effects.
