GE Energy Unveils Enhanced Jenbacher Gas Engines

Posted on March 16, 2009

GE Energy is introducing a next-generation, ultra-efficient Jenbacher ‘Type 6’ gas engine to help European Union (EU) member states comply with a directive to install new industrial, commercial and residential cogeneration systems that boost energy efficiency while reducing local fossil fuel consumption and greenhouse gas emissions.

Evaluated in “pilot” combined heat and power (CHP) plants supporting two commercial horticultural greenhouse sites in the Netherlands, GE’s new ‘6F’ gas engines recently reached a critical performance milestone of 10,000 operating hours. Even more impressive for customers: the new 3.3-megawatt (MW) 6F units demonstrated an increased output of up to 10% and a crucial 1% hike in electrical efficiency over existing systems.

The successful evaluation of the 6F is the latest accomplishment for GE’s proven Jenbacher Type 6 engine family. In 2008, GE announced the commercial debut of its four-MW model, the J624, the world’s first 24-cylinder gas engine for commercial power generation, particularly cogeneration. The 6F design benefitted from GE’s development of the J624 as GE’s engineers were able to adapt the more powerful J624’s optimized combustion system to the new 1,500 rpm Type 6F version engine models.

The key to the 6F’s increased performance is the capability to run the engine at a higher break mean effective pressure of 22 bar due to enabling technologies such as steel pistons with optimized geometry, which have higher peak pressure capability compared to aluminum pistons.
