Most powerful gas turbine for the power plant Irsching
2007-Dec-19
The SGT5-8000H gas turbine, developed by Siemens, was completed at the end of April 2007 in Berlin. With a capacity of 340 megawatts (MW), it is the world`s biggest and most powerful gas turbine.
Here also the shape of the turbine blades has an important function. For this purpose the Siemens power plant specialists developed new, high-strength materials for turbine vanes that can also withstand high temperatures, as well as new burner and combustion chamber technologies.
Exceptionally tricky: The nano-coatings of the turbine blades to resist the heat of combustion gases of up to 1.500 centigrade.
The gas turbine is extremely flexible to operate. It has a shorter warmup time and makes faster power load changes possible. This is possible thanks to its air-based cooling technology. Air is always immediately available, by contrast to the much more complex steam cooling process. (PN 2007.01)
