In September 2007, a major power generation company received the order from a Chinese steel manufacturer to build the first large blast furnace gas (BFG)-fired combined-cycle power station in China.
In 2008 the power generation company supplied, among other things, two gas-turbine driven centrifugal compressor branches with EagleBurgmann gas seals in a tandem arrangement and put them successfully into service in December 2009.
In December 2009, EagleBurgmann China established a new Dry Gas Seal (DGS) Service Center in the EagleBurgmann Dalian factory in order to meet local Chinese customer and market requirements.
The opening of this new facility now offers the region's customers a local dedicated center of excellence that provides a static gas seal testing and repair facility. "As a result, customers will benefit from more rapid turnaround times, improved service and local access to the wealth of specialist sealing expertise that EagleBurgmann has at its disposal" said Simon Guo, CEO of EagleBurgmann China region.
Mechanical seals are used as shaft seals in pumps, agitators, compressors and other rotary machines handling liquid and gaseous media. The process pressures which have to be contained by the seals range from vacuum to more than 400 bar. In some cases, the chemical and thermal stability required of the mechanical seal is very high. The design of the seal and the choice of material from which it is made play a crucial role in making sure that it operates reliably for a sustained length of time under the conditions for which it was designed and for which the material was chosen.
