Avoidance of generator damage resulting from condensation on live parts - ebook
Ref.-Ordering Number: VGB-S-164-12-2016-10-EN-ebookThe moisture contained in gaseous substances condenses on impact with colder surfaces to a greater of lesser extent, depending on the ambient conditions and in particular on pressure and temperature. If this occurs in the area of non-insulated electrical connections inside the generator, it is hardly possible to avoid electrical faults. Several cases of damage to power plant generators with similar causes and developments resulting from condensation as outlined above have provided grounds for the VGB Project Group on Generators to analyse the causes and compile recommendations for action to avoid such damage in future.

Recommendations for thermal/mechanical generator protection - ebook
Ref.-Ordering Number: VGB-S-164-11-2016-08-EN-ebookTo 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.

Chimneys for Operation without Flue Gas Reheating after FGD - ebook
Ref.-Ordering Number: M643e-ebookThe 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.
