This VGB-Standard deals with flue gas desulphurisation (FGD) in large combustion plants. At this point, no additive processes, which can be employed in combustion, are considered. Here, only plants downstream of combustion are considered. The aim of the instruction sheet is to describe procedures and special designs so that every reader finds his type of plant described. Operating experience is what is most important. If special plant-specific problems occur, the corresponding plant type is pointed out. First experience is also important since the cooperation of experienced operating personnel is necessary for planning new plants. There is otherwise a risk that operating experience with existing plants is not considered.

With this VGB-Standard options are demonstrated to reduce fire hazards by constructional means and to respond to them by appropriate procedures, to detect a fire that has already started as soon as possible, and to fight the fire effectively taking into account the specific properties of this fuel.

The present VGB Standard S-175 explains fundamental concepts and compiles the threats and the security requirements derived from them in a structured and clear manner. In addition, recommendations for actions regarding the individual requirements have been compiled by way of example for improved understanding and  quick implementation. It is envisaged to provide in a library both additional aids for practical application and advice in response to current events.

This VGB-Standard presents methods of using operational and adapted technical measures to keep the risks of fire and explosion as low as possible. In this way, potential hazards can be avoided by the deployment of suitable operational workflows. Fires can be detected without delay and combatted effectively under the special conditions of the type of plant concerned. The formation of potentially explosive atmospheres can be limited by operational and technical measures.

Very substantial advances have been made over the last couple of years in the field of heat transfer surface cleaning which are included in the present revision of the Standard (cf. first edition). New methods like explosion cleaning are now included in the text.

The aim of these recommendations for improving H2 safety is to provide information for designing, constructing, modernising/refurbishing and operating hydrogen-cooled generators in power plants.

The purpose of this VGB-Standard is, with respect to the electrotechnical systems and components of a power plant, to set out what essential rules should prevail regarding their characteristics and operation, and how these can be applied for purposes of implementing BetrSichV. In addition, it intends to make a contribution to a uniform understanding of the risk assessment of all electrotechnical systems and components of a 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.

Within this instruction sheet protective measures, based on relevant actual standards, against the actions of deviating vehicles (vehicle impact) on buildings, civil structural parts and mechanical components in conventional power plants and comparable industrial facilities are described. The purpose of the instruction sheet is to give practical instructions for "guard devices" in accordance with VGB Guideline "Indication and Handling of Loads when Designing Conventional Power Plants", VGB-R 602 Ue (section 2.5.3, Impact Loads).

The enactment of the amended version of the 13th Ordinance for the Implementation of the Federal Immission Control Act (13. BImSchV; Ordinance on Large Combustion and Gas Turbine Plants, [1]) in July 2004 effectively aligned the German ambient pollution control requirements with the current European regulations. Apart from redefined emission limit values for flue gas contents, a significant change (in the case of discharge by chimney) is the dropping of a minimum flue gas temperature of 72° C at the chimney outlet. For plant design, this means that reheating of the flue gases after wet flue gas desulfurization is no longer necessary.

Monitoring, limiting and protection devices must satisfy stringent requirements in order to afford safe and reliable operation of gas turbine units. The present revision was aimed at considering the present state of the art and the current codes of practice and ISO and VDMA standards. This Standard applies to stationary gas turbines (single-shaft and multi-shaft turbines) used to drive generators and other machinery.

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.

To detect incipient damage to generators in power plants, protective equipment is installed. For electrical protection, in 2012 VGB published recommendations in the VGB-Standard VGB-S-025 “Electrical Generating Unit Protection”. The VGBStandard in hand, VGB-S-164-11, shows the protective measures that can be taken when thermal limits are exceeded or leaks and other malfunctions occur. These protective measures relate to so-called thermal/mechanical generator protection and cover generators for thermal power plants, hydroelectric power plants and wind turbines.
