2 MW gas engine launched by Siemens

16 June 2017

Siemens has launched its new 2 MW gas engine E-series, which includes the SGE-86EM for the 50-Hz market and the SGE-100EM for the 60-Hz market. The new engine, the original of which was inherited by Siemens in its purchase of the Dresser-Rand business in 2015, has 12 cylinders and offers high cylinder volume, high displacement and, says Siemens, best-in-class efficiency in the market. These two engines are intended to broaden Siemens’ range of efficient products and solutions for low-MW range distributed power generation. The expanded gas engine portfolio now ranges from 300 kW to 2 MW.
In 2015 Siemens acquired Guascor engines and generator sets as part of the Dresser-Rand product portfolio. Legacy Guascor engines are recognised as robust and efficient machines that deliver heat and power and perform reliably in critical and demanding applications.
The new E-series gas engine is based on the thermodynamic Miller cycle combustion technology. With a mechanical efficiency of about 47 % and an electrical efficiency of 45.4 %, the engine offers a good level of performance for both prime power generation and cogeneration applications. The new engine series’ capacity to deliver on-site power, heat, and cooling for a wide variety of commercial, industrial, and municipal applications translates into an excellent cost-performance ratio, as born out during 3000 operating hours and comprehensive testing at Siemens’ Engine R&D Centre in Miñano, Spain.
Siemens’ E-series engines are said to be especially well-suited for renewable energy and waste-to-energy, industrial power generation and cogeneration, and combined heat and power (CHP) applications.
