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.

As a result of the increasing importance of district heating in the context of energy supply, the VGB Expert Committee "Water Chemistry in Thermal Power Plants" has produced a revised edition of the Instruction Sheet "Quality Requirements for District Heating Water".

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.

The Guideline applies to the entire technical documentation (technical plant data and documents) which is necessary in the performance of projects, e.g. in planning, erection and commissioning to ensure future operation and maintenance, taking account of the type of energy supply unit concerned.

This instruction sheet applies to the characterisation of the grindability of lignites according to the Impact Grundability Index PMI (in German: Prallmahlindex PMI). This process variable characterises the grindability of pulverised fuels under the conditions of impact crushing, in particular for beater wheel, beater or fan mills.

Diese Richtlinie gilt für die Charakterisierung der Mahlbarkeit von Braunkohle nach Prallmahlindex. Mit dem Verfahren werden relative Kennwerte zur Mahlbarkeit unter den Bedingungen der Prallzerkleinerung ermittelt, die für die Auslegung und den Betrieb von Mahltrocknungsanlagen an Staubfeuerungen, insbesondere von Schlagrad-, Schlägeroder Ventilatormühlen, von Bedeutung sind.

The first edition of the instruction sheet “Analysis of FGD gypsum” was elaborated and published by the joint Working Group of the "Bundesverbandes der Gipsindustrie e.V." and VGB PowerTech e.V. to assure a high quality of FDG gypsum in coal-fired power plants. Due to new analysis methods the Project Group of the VGB Working Panel „Analysis“ revised the second edition and co-ordinated it with the Federal Association of the Gypsum Industry (Bundesverband der Gipsindustrie e.V.).

 

Since about 1985, fluidized bed combustion (FBC) has greatly extended the possibilities for operating power plants on the basis of solid fuels economically and in an environmentally acceptable manner. In addition to the system-inherent possibilities for infurnace emission reduction, FBC can be adapted to an especially broad range of fuels, some of which with a very high ash content. The possibility of using pressurized fluidized bed gasification and combustion systems in coal/combined cycle power plants and thus achieving substantial improvements in resource conservation and CO2 reduction have been technically demonstrated.

 

We expect that this second edition of the Instruction sheet, which is now entitled 'Recom-mendations for Design and Warranties of Waste-fuelled Steam Generators' will not only be beneficial for the purchasers but also for the suppliers of waste incineration facilities.

 

Der bisherige Erfolg dieses Merkblattes gab Anlass zu einer Weiterentwicklung und Anpassung an die heutigen Rahmenbedingungen. Die legislativen Änderungen, insbesondere die Harmonisierung der europäischen Regelwerke, aber auch die Neuerungen im Handelsrecht machen textliche Anpassungen erforderlich.

 

The VGB Instruction Sheet “Coal Handling in Power Plants” contains a collection of experience and recommendations which was prepared to the best of our knowledge but cannot always completely reproduce the state of the art. It provides a summary of information in the field of power plant coal handling which provides the user with a better overview of the specialist area and the associated regulations. The Instruction Sheet is therefore an important instrument for more efficient cooperation between those concerned. Complete application or application of excerpts must be agreed upon between the clients and the suppliers. There is no obligation to apply it. Liability, also for the factual correctness of the presentation is excluded. Likewise, rights under patent law and other property rights are to be clarified by the user on his/her own responsibility.

It is requested that the experience gained with the application of this Instruction Sheet, and that, by way of suggestions for improvements, any shortcomings found in the presentation as well as any possibilities that arose for confusing interpretations be reported to the VGB office for evaluation. This can be a starting point for addenda or alterations.
