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.

This VGB Standard describes possibilities and methods for condition monitoring and performance of tests and inspections in due consideration of hazards especially arising from steam and pressure in components of steam boiler plants, pressure vessel installations and water- or steam pipework.

Fire-fighting operations by fire brigades in onshore wind turbines are almost impossible because of their height and resulting difficulty of accessing them. For this reason, fire prevention, early detection and early fighting of a fire, and the self-rescue of persons present in the installations during a fire are key considerations.

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 the VGB-Standard VGB-S-042-0-2018-01-EN is to specify and explain methods and systems for the chemical treatment of make-up water, boiler feed water, steam and condensate for the operation of water/steam cycles.

This guideline is meant to provide a standardized basis for acceptance and operating tests of air-cooled water steam condensers. Its scope of application is limited to the testing of the condenser itself and the exhaust steam duct up to the terminal point of supply.

More than twenty years ago, in 1994, the first edition of this standard was published in response to the rapid technological development and the growing importance of condensers in plant construction. Now that the standard has been tried and tested in many respects over the last few decades and the economic viability of a plant continues to be heavily influenced by the operation of its condensation system, it has been decided to maintain and update the standard. A fundamental revision was not necessary.

The editorial team has decided to take the steam turbine and the generator from the VGB-R 116 “Preservation of Power Plants” (republished as VGB-S-116-00-2016-04- EN “Preservation of Power Plants”), to add a section on the gas turbine and to publish both together in this revised VGB standard “VGB-S-036-00-2017-04”.

Over a lengthier period experience was gained with VGB-Guideline VGB-R 503e which is now taken into account in this edition of VGB-Standard VGB-S-503-00- 2017-06-EN.
