Global technology leader Siemens and E.ON, one of the world’s leading utility companies, have reached a significant milestone in the area of 3D-printing for the energy sector.
The world’s first 3-D printed burner for an SGT-700 gas turbine has been in operation for one-year at E.ON’s combined cycle power plant in Philippsthal in the German state of Hessen and the results are impressive.
The burner has been operating for over 8,000 hours with no reported issues, said a statement from Siemens.
In 2017, the technology giant began printing gas turbine burners using selective laser melting technology and they were the first burners produced by its intelligent burner manufacturing (Ibuma) program in Finspång, Sweden.
Each burner head is manufactured in one piece compared to traditional methods that required 13 individual parts and 18 welds, it stated.
Design improvements, such as the pilot-gas feed being part of the burner head instead of the outside fuel pipe, allow the operating temperature to be kept lower, thus contributing to a longer operational lifespan of the components and, ultimately, the gas turbines.
Working side-by-side, Siemens and E.ON became “co-creators” on this project, realizing benefits on both sides.
Siemens is accelerating the development of innovative design and manufacturing technologies and E.ON is benefiting from these innovations at an early stage.
“As an energy service provider, precision and consistency are an absolute requirement for us,” said Niklas Lange, project manager at E.ON Energy Projects.
“Additive manufacturing not only delivers this, but in our experience it can even improve performance compared with older models,” he stated.
“We like to help drive innovation,” remarked Lange. “When I saw these burners from Siemens in Sweden, I knew we could benefit from using them in a commercial turbine. It’s also important to note that our hands-on collaboration with Siemens has been a key to deliver performance to our customer.”
Acording to him, the additive manufacturing is revolutionizing the development and production of components – not just in the automotive and aerospace industries but also in the energy sector.
“For example, it can be difficult for conventional manufacturing technologies to produce more efficient or low-emission turbines with higher temperature tolerances. 3-D printing now makes it possible to produce almost any structure imaginable. The process allows turbine components like gas turbine blades and vanes to be cooled through complex internal ducts, which improves their efficiency,” he noted.
Vladimir Navrotsky, the chief technology officer for Siemens Power Generation Services, Distributed Generation, is excited about the future of additive manufacturing and Siemens’ leading role in accelerating its use.
“These early results from the Ibuma burner with E.ON validate our belief that this technology is a game-changer. We appreciate E.ON’s active participation and commitment to driving innovation and look forward to our continued close collaboration,” he added.
Siemens began investing in metal 3D printing back in 2008 and developed the technology specifically for power generation. In 2012, the German group installed the first EOS M280 SLM printer and adapted it for burner repairs.
