Für eine wirtschaftliche Herstellung und einen einwandfreien Betrieb von Produktionseinrichtungen sind als eine wichtige Voraussetzung eindeutige und umfassende Vereinbarungen über Auslegung, Abmessungen und Errichtung zu treffen. Dies ist bei Krananlagen besonders wichtig, weil hier verschiedene Fachdisziplinen, wie z. B. Maschinenbau in Verbindung mit Beton- und Stahlbau, an der Herstellung beteiligt sind.

This Guideline addresses the lifecycle management of reinforced concrete cooling towers. Lifecycle management comprises maintenance of the structure and measures to ensure the safety of a cooling tower. Effective lifecycle management must be preventive and knowledge-based.

As a result of particular impacts and stresses affecting reinforced concrete cooling towers and chimneys and strengthend by their special structures and conditions of operation, adequate instructions are required for contractors initially applying or renewing surface protection systems. This Guideline therefore takes the form of additional technical stipulations to supplement the existing standards and codes. In this spirit, the Guideline is intended to assist the customer as an aid to decision-making and a basis for inviting tenders, placing orders and performing work of this kind. The customer in this context may be the owner and/or operator or a company employed by these.

This guideline applies to spring elements for foundations in accordance with:

-  DIN 4024-1 Machine foundations; flexible structures that support machines with rotating elements

- DIN 4024-2 Machine foundations; rigid foundations for machinery with periodic excitation; section 1a supporting machines with rotating masses.

Diese Richtlinie beinhaltet die allgemeine Vorgehensweise bei Qualifizierungen und legt die Schritte für die  Qualifizierung (Eignungsnachweis) einer zerstörungsfreien Prüfung fest. Die Qualifizierung soll sicherstellen, dass die zum Einsatz kommenden Prüfverfahren, Prüftechniken und Prüfgeräte geeignet sind, eine geforderte  Prüfaufgabe unter Praxisbedingungen zu erfüllen. Diese Richtlinie enthält auch Anforderungen an das   Prüfpersonal.

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.

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.

This Guideline applies to ash handling facilities for steam boilers, extending from the collection points of the combustion residues up to the places of dispatch from the delineated power station area.

Sections B1 to B6, present as a collection of data in VGB guideline VGB R 170 B, are to be understood as a catalogue of requirements for the specification of and/or the terms of reference for instrumentation and control equipment projects.

Dieser Leitfaden soll für alle Lieferungen und Leistungen eines Versorgungsunternehmens eine praxisnahe Interpretation des QM-Regelwerks bieten. Er gibt somit Anregungen und Hilfestellung beim Aufbau eines unternehmensspezifischen QM-Systems.

Due to the development towards larger outputs in power Stations, it was necessary for the design of air extraction pumps for surface condenser units to keep pace. For this purpose water-, air- or steam ejectors and  water ring pumps or combination of these can be used. The design of the suction pumps was adapted to the development of unit size.

The guidelines are intended to provide information to the operating company of combined heat and thermal power plants so that they can order the correct piping for condensers and heat exchangers and also to help them prevent faults and damage. To allow a better understanding and to assess pipe damage, the guidelines contain material-specific explanations and information in the form of photos illustrating typical damage symptoms.

The "Tubes for condensers and other heat exchangers for the operation of steam turbine plants" guidelines are currently split into three material groups (VGB-R 106 "Copper Alloys", VGB-R 113 "Stainless Steels" and VGB-R 114 "Titanium"). The guidelines are intended to provide information to the operating company of combined
heat and thermal power plants so that they can order the correct piping for condensers and heat exchangers and also to help them prevent faults and damage.

The VGB-Guideline R108e aim to form a foundation that operators can use to compile their own fire protection strategies, tailored to suit the particular plant in question. For this reason, a number of suitable steps are given as examples.

The "Tubes for condensers and other heat exchangers for the operation of steam turbine plants" guidelines are currently split into three material groups (VGB-R 106e "Copper Alloys", VGB-R 113e "Stainless Steels" and VGB-R 114e "Titanium"). The guidelines are intended to provide information to the operating company of combined heat and thermal power plants so that they can order the correct piping for condensers and heat exchangers and also to help them prevent faults and damage.

lt should always be remembered that placing excessive requirements on the start-up and loading behaviour of turbines will reduce the serve life of certain components . Mention is also made of the gentle mode of operation nowadays possible when suitable monitoring equipment or automatic systems are used .
