Das vorliegende Merkblatt wurde von einer Arbeitsgruppe des Arbeitskreises "Korrosion von metallischen Komponenten in Rauchgasentschwefelungsanlagen (REA)" im VGBArbeitskreis - Werkstofftechnik konventionell" erarbeitet, wobei die herstellende Industrie mit einbezogen wurde. Veranlassung für die Erstellung des Merkblattes war eine zunehmende Anzahl von Schädigungen an Gehäusen, Lauf- und Leiträdern von REA-Suspensionspumpen [1, 2]. Dieses Merkblatt befasst sich vorwiegend mit den Hinweisen für die Bestellung von Gußstücken aus Duplex-Werkstoffen für Gehäuse, Lauf- und Leiträder für REA-Suspensionspumpen.

Measurement systems in conventional and regenerative power and heat generating plants are an essential part of instrumentation and control systems. They provide the information needed to operate the generating plant and, with the exception of local measuring devices, are connected with the automation systems without interposition of the operating personnel. This lends special importance to the measurement systems.

Although no overwhelming evidence exists, organic acids and carbon dioxide have nevertheless been implicated as contributors to corrosion problems within the steam-water circuit. A dedicated group of international scientists, power plant chemists and turbine manufacturers has been commissioned under the auspices of the VGB PowerTech e.V. to examine and document the impact of organic matter and dissolved carbon dioxide on materials of construction in the steam-water circuit of power plant. This VGB Working Group "Organic Matter and Carbon Dioxide in Steam- Water Cycles" has produced an Instruction Sheet for organic matter and dissolved carbon dioxide in plant cycle chemistry of power plant.

This Instruction Sheet is subdivided into two sections. The first section describes the test procedures employed to determine the suitability of soft rubber linings in flue gas desulphurization plants while the second section deals with the testing criteria and standard values utilized to assess the service life of these soft rubber linings in flue gas desulphurization plants. The data presented are based on the collective experience acquired by the operators of flue gas desulphurization plants as well as by the manufacturers of soft rubber linings as corrosion protection systems for these plants. The publisher shall be exempt from any liability, including the factual accuracy of the statements contained herein. Issues relative to patent and/or other related rights shall be clarified by the respective owner of the patent rights as required.

The VGB-Standard VGB-S-120 lists measures which are conducive to maintaining cleanliness in the plant (in mechanical, electrical and chemical regards) during maintenance and modification work.

The Instruction Sheet on hand is intended to replace Instruction Sheet M 407 G, "Bases for Planning, Ordering and Verification of Warranted Performance for Demineralization Plants with Ion Exchangers", the first and latest edition of which was published in 1986 and which defined the quality characteristics required for demineralized water for the first time. The Instruction Sheet had been created in cooperation with FIGAWA (Federal Association of Gas and Water Engineering Companies) in Cologne and FDBR (Professional Association for Boiler, Pressure Vessel and Piping Technology) in Düsseldorf.

Responding to growing demands of the European environmental legislation, power plant operators are increasingly focusing on the topic of dust emission measurement again. Several independent studies provide evidence that the generally applied methods of dust measurement exhibit a degree of crosssensitivity to sulphuric acid aerosols not to be ignored. Without knowledge and consideration of these interrelations, serious measurement errors can occur, always falsely indicating excessive dust concentrations.

Der VGB-Standard VGB-S-002-05 stellt für Windkraftanalgen die grundlegenden Definitionen und Kennzahlen zur Beschreibung von Zuständen bereit und sichert deren einheitliche Verwendung und damit deren Eindeutigkeit. This publication provides the basic definitions and parameters for describing conditions of wind power plants and ensures their consistent usage and therefore their clarity.

The necessity of uniformly representing the inspection and evaluation of inservice components in due consideration of damage reported as well as the improvement of manufacturing technology and examination techniques led to the establishment of this guideline.

In der heutigen Zeit erwarten wir von dem Kraftwerker Fähigkeiten und Fertigkeiten in einem sehr breiten und heterogenen Handlungsspektrum. Der Rahmenstoffplan beinhaltet nicht nur die altbekannten „harten" technischen Kenntnisse sondern auch „weiche" Themen wie das Unterrichtsfach „Professionelles Arbeiten“.

The objective of the VGB-Standard is to safeguard the required quality criteria for the complete production processes up to and including commissioning and first start-up. It is intended as a pragmatic aid for the users.

Seit der Erstausgabe 2003 (VGB-R 210) haben sich vereinzelt neue Entwicklungen, vor allem aber geänderte Bedingungen für den Betrieb eines steinkohlengefeuerten Kraftwerkskessels herausgeschält. Neue Anforderungen seitens der Gesetzgebung aber auch seitens der sich stark veränderten wirtschaftlichen Randbedingungen erforderten eine Überarbeitung und Modernisierung des Textes.

The precursor of this Standard the VGB-Bulletin “Charakterisierung von Kraftwerkskohlen” (VGB-R 210; Characterisation of Power Plant Coals) appeared 12 years ago (2003). Some new developments, but, in particular, changed operating conditions for hard coal fired power plant emerged since. New statutory requirements and also severely changed economic challenges demanded a revision and modernisation of the text.
