Conventional Power Plants - Applications

GF Piping Systems Applications in Conventional Power Plants Industrial Cooling Water Cooling of media used is a main requirement in a variety of processes. Either the medium is cooled directly in the process or indirectly via secondary cooling loops. Water used for power plant cooling is 01 chemically altered for the purpose of extending the useful life of the associated equipment, and to ensure greater system efficiency. Chemical Conveyance Safe conveyance of environmentally hazardous media is a must. The risk of stress cracking in piping systems has to be minimized. Double containment pipe systems can be implemented to virtually 02 exclude the risk of accidents. The technology permits jointing the inner and outer pipelines separately, allowing pressure testing of both lines independently. Water Intake Lines Water intake lines convey raw water from the source, rivers or the sea, to the storage area before its treatment. Inhibitors such as biocides are added to prevent biofilm build up as well as incrustation. 03 Since long distances are bridged, a corrosion free solution is needed. Often involving large diameters, a complete system is a must. Flue Gas Desulfurization Flue gas desulfurization (FGD) is an essential key technology in environmental protection to effectively remove sulfur dioxide from the outgoing flue gas e.g. by wet lime method or seawater FGD. As several 04 aggressive chemicals and abrasive media are used, the correct plastic system is critical to provide a reliable and durable system. Water Distribution Connecting water main lines, service lines and hydrant water supply, both reliably and safely, is the key success factor for any plastic piping system. With a wide range of components, sizes and jointing 05 technologies, a complete solution is available up to d1 200. Larger dimensions are available on request. Gas Distribution The gas connection from the power plant perimeter to the distribution around the site is critical, therefore a safe connection is required. With gas distribution lines generally operating at 0.1 to 10 bar 06 and typically dimensioned in the range of d90 to d225, many proven and reliable systems are available. Fire Fighting Our ecoFIT pipings are FM approved and can be used for underground fire extinguishing pipelines up to the dimension d1 200. Sprinkler lines and connections must meet local fire laws. Corrosion-free and 07 reliable jointing systems are a key criteria. Safety Showers Safety showers are an important part of industrial health and safety concepts. With our pre-insulated COOL-FIT ABS Plus system, we offer an energy efficient and durable solution. Under certain 08 conditions, COOL-FIT ABS Plus can even be an alternative to conventional heat tracing on metal pipes. Slurry Transfer In order to transport the ash slurry waste away from the process, a corrosion-free, highly abrasion resistant system is needed. Involving long distances, correct and reliable jointing of the 09 system is a must. As part of the system, a complete range of automation (measurement and control technology) is required.

Intelligent plastic solutions to successfully manage your power plant Water Treatment Power stations require high volume of water in high water quality to feed boilers, processes, and cooling systems. Avoiding contamination, scale formation and corrosion in these systems is essential. 10 Waste water needs to be neutralized before being discharged into public sewage treatment plants. All these operations must be controlled correctly with automation systems. Desalination Salt is removed from sea water to produce fresh water. This provides the water source where natural water is scarce. To maximize energy efficiency, desalination plants are often linked to cogeneration 11 plants. Prefabrication of parts used for the reverse osmosis skids, is an important area in which we support. Makeup Water The boiler feed water is treated to remove soluble salts in upstream process stages. Subsequently, soluble gases are removed, especially oxygen and carbon dioxide. Makeup water is highly purified 12 before use as well. Various chemical additives are metered in depending on the boiler type, chemical mode of operation and residual salt content. Compressed Air The compressed air system must be leak proof and durable over its entire lifetime. To compensate pressure surges, it must be flexible and not transmitting vibration. The smoothness of the 13 inner surface ensures minimal frictional losses in the piping system and maximum efficiency. This results in significant energy savings and reduced operating costs of the system. Hot & Cold Water in Buildings Industrial facilities have one thing in common: they all need an environment-friendly heating and cooling system as well as a reliable supply of drinking water. System solutions in compliance with 14 specified drinking water qualities and with diverse connection technologies are designed for particular building situations. High flexibility can be offered thanks to prefabrication of the installation components.
