    ABSTRACT

    With more stringent emission limits with time, including NOx and N2O, and due to the high costs of secondary measures for NOx emissions reduction, knowledge of primary NOx and primary N2O is very important. With this knowledge, primary NOx and primary N2O can be reduced at low costs and in this way costs for secondary measures are much reduced as well. By applying the knowledge presented, the project costs of a CFBC plant can be lower than those of a PFC plant.

    Knowledge regarding primary NOx and primary N2O, and their models, is useful for operators of PFC and CFBC regarding the influence of (the change of):

    • Fuel, with PFC and CFBC
    • Lambda, with PFC and CFBC
    • Temperature, with CFBC
    • Addition of limestone to the bed, with CFBC.

    Knowledge regarding primary NOx and primary N2O, and their models, is useful for suppliers of boilers, burners, etcetera, regarding the influence of (the change of):

    • Design, with PFC and CFBC
    • Fuels and fuel flexibility, with PFC and CFBC
    • Conversion of the boiler for other fuels, with PFC and CFBC
    • Developing assisting systems / software, with PFC and CFBC
    • Temperature, with CFBC
    • Addition of limestone to the bed, with CFBC.

    With this thesis, the mathematical models of primary NOx of CFBC, primary NOx of PFC and primary N2O of CFBC were improved. The models are based on chemical aspects, such as thermodynamics, kinetics and reaction mechanisms.

    The aim of this “Best Practices” study is to identify the approaches taken by the German power industry for building and operating coal-based power plants and to compile these in one place. This study provides a comprehensive overview of the aspects that are important in all phases of a power plant lifecycle. Existing best practices and guidelines are referenced.

    Failures in power plants can be costly and efforts should be directed to prevent such events. Methods using Reliability Availability Maintainability (RAM) tools are well known to answer questions on target values for reliability and availability of a plant, capacity expansion planning, optimum redundancy, maintenance optimisation, spare parts management etc.. This report is available as an electronic PDF-document (ebook) of 1,167 pages. The largest part of the report consists of evaluations of various components that are identified by the power plant identification system (based and referenced on Kraftwerk-Kennzeichensystem – KKS function keys) and are used in different types of power plants (hard coal and lignite-fired power plants as well as combined cycle plants). ----- Ungeplante Ausfälle in Kraftwerken können kostspielig sein. Daher sollten diese vermieden werden. Dafür geeignete Methoden, die Reliability-Availability-Maintainability (RAM)-Tools verwenden, sind bekannt und werden angewendet. Sie liefern Hinweise und Ergebnisse, um die Zuverlässigkeit und Verfügbarkeit einer Anlage, die Planung von Kapazitätserweiterungen, optimale Redundanzen, die Instandhaltung, das Ersatzteilmanagement usw. zu optimieren. Solche RAM-Tools benötigen jedoch verlässliche Zuverlässigkeitsdaten. Nur wenige Projekte unterstützen die Erhebung solcher Daten, auch weltweit und vor allem über einen längeren Zeitraum. Dieser Bericht ist als elektronisches PDF-Dokument (ebook) mit 1.167 Seiten verfügbar. Der größte Teil des Berichts besteht aus Auswertungen verschiedener Komponenten, die durch das Kraftwerkskennzeichensystem (KKS) festgelegt werden und in unterschiedlichen Kraftwerkstypen (Steinkohle- und Braunkohlekraftwerken sowie GuD-Anlagen) eingesetzt werden.
