Erlangen, Germany, December 13, 2011 — Siemens is building a new combustion test center for gas turbines near Berlin. The planned test center in Ludwigsfelde will play an important role in the design and ongoing development of Siemens gas turbines.
Up to now, Siemens has relied on external test facilities in evolving its gas turbine burners. In the future the company will be able run more tests, as in-house trials will no longer be dependent on the availability of external capacities.
The new test center is to have three cells for investigating combustion processes under real-life service conditions. In a gas turbine, natural gas or fuel oil is mixed with air under high pressure and combusted in up to 24 identical burners.
Gas power plants can be started up very quickly and are highly versatile in on-line operation, but the conditions of the combustion processes under part and full load differ significantly.
In the tests, various parameters such as output, efficiency, emissions and the stability of the flame are studied on a single burner on the test bed. The Ludwigsfelde site has access to an adequate supply of natural gas via a local pipeline and is also connected to the high-voltage power grid.
What is more, natural gas and fuel oil can be substituted in the combustion trials by mixtures of alternative fuels such as hydrogen, ethane, propane and butane. As a leading provider of modern gas turbines, Siemens holds the world efficiency record with a proven efficiency of 60.75 percent in combined-cycle operation. In a combined cycle power plant, the hot exhaust from a gas turbine is used to raise steam that drives a steam turbine to boost the overall power output.
The importance of Siemens Energy's Berlin location is reflected in its recent investments. Just this year, the company spent 17 million euros on expanding and renovating its test facility in Berlin-Moabit, in which fully assembled gas turbines are tested under power plant conditions. A new drilling station for gas turbine casing parts has also been installed there at a cost of 13 million euros.
