The world leader in gas turbine technology, Siemens launched its cutting-edge HL-class gas turbine last September, paving the way to the next level of efficiency and performance.

The evolutionary development step, derived from proven Siemens H-class technology, combines a series of new but already-tested technologies, like super-efficient internal cooling features for blades and vanes and an advanced combustion system to increase firing temperature. The result is a technology carrier to the next level, with a combined cycle efficiency beyond 63 per cent and a clear midterm goal of 65 per cent. The new Siemens HL-class consists of three engines: SGT5-8000HL, SGT5-9000HL, and SGT6-9000H.

With 88 turbines sold, the Siemens H-class is the most successful gas turbine in this efficiency category in the global market today. The largest single order to date for the SGT5-8000H turbine has come from Egypt, where a total of 24 H-class engines are being installed in the Beni Suef, Burullus, and New Capital power plant projects.

The Lausward combined cycle plant at Düsseldorf Port has set three new world records: The power plant with the SGT5-8000H gas turbine as its key component achieved a net efficiency level of about 61.5 per cent, with a maximum net electrical generating capacity of 603.8 MW. The plant is also able to provide 300 MW(th) of heat for the city of Düsseldorf’s district heating network. The installation of an H-class gas turbine in this kind of combined heat and power plant (CHP) has proven to be one of the most efficient ways to convert fuel into usable energy. The high fuel efficiency of the plant plays an important role in meeting economic requirements and reducing the environmental impact.

Siemens is the leading supplier of gas turbines for combined cycle power plants in Vietnam. The company has successfully implemented a number of big power projects, such as Phu My 2-1 Extension, Phu My 3, Ca Mau 1 & 2, and Nhon Trach 2, where the SGT5-4000F - a well-proven 50 Hz gas turbine with an outstanding reliability and availability - has been utilized. Siemens has indicated a strong willingness to participate in new power plants in Vietnam with its next-generation technology.

“Low lifecycle costs and an excellent return on investment right from the start are just two of the benefits that our gas turbine portfolio offers,” said Mr. Thomas Hagedorn, Head of Sales Asia Pacific at Siemen’s Power and Gas Division. “Our gas turbines fulfill the high requirements of a wide spectrum of applications in terms of efficiency, reliability, flexibility, and environmental compatibility. With our proven experience in Vietnam, we are in the best position to support Vietnam’s power generation sector in meeting the growing demand for electricity stemming from rapid economic and population growth.”

“We can also arrange financing for new power projects in Vietnam,” he added.

Thanks to Siemens’ technology, Phu My 2-1 Extension, Phu My 3, Ca Mau 1 & 2, and Nhon Trach 2 are among the most efficient and environmentally-friendly power plants in Vietnam. They are not only making remarkable contributions to the national grid but are also bringing sustainable profits to investors.

In particular, the Nhon Trach 2 combined cycle power plant (CCPP), which was built together with local turnkey contractor LILAMA, has achieved a remarkable rating for having the shortest construction time and stable operations as well as for being one of the most efficient and cost-effective power plants in the country.

“With the success from this project we look forward to continuing to participate in the implementation of the Nhon Trach 3 CCPP,” said Mr. Hagedorn. “And after careful consideration of all aspects, we think that the Siemens F class can still be used for this new power project, but of course we are open to the potential of supplying our H class technology in Vietnam should the opportunity arise.”

Siemens welcomed Vietnamese Prime Minister Nguyen Xuan Phuc and his delegation to visit its gas turbine in Berlin in 2017. The gas turbine, SGT5-4000F, as seen in this photo, has been supplied to a number of big combined cycle power plants in Vietnam.

Siemens’ gas turbines are operating in more than 60 countries with four product lines: E class, F class, H class, and HL class. The Siemens gas turbine range has been designed and tailored to help meet the company’s customers’ challenges in a dynamic market environment. Siemens has provided proven technology, with more than 6,900 installed heavy-duty, industrial, and aeroderivative gas turbines.

According to Mr. Hagedorn, Siemens will continue its proven approach to developing new gas turbine frames utilizing key technologies, including 3D blading, advanced combustion systems, super-efficient internal cooling features, advanced thermal barrier coatings, and turbine blade 4.
