GE Unveils Waukesha APG1000 Gas Engine

Posted on August 23, 2011

Expanding the company’s lineup of biogas engines for a wider range of power outputs, GE has introduced its Waukesha APG1000 gas engine, which can use a broader variety of biogases, including gases from landfills, wastewater treatment plants and agricultural waste. GE unveiled the 1 MW APG1000 gas engine at the Solid Waste Association of North America’s 2011 WasteCon Conference in Nashville, Tennessee, U.S.A.

The Waukesha unit’s expanded biogas capabilities are the result of an 18-month redesign and testing initiative that includes modifications to the combustion chamber, a new spark plug design and a new fuel control system that simplifies engine start-up and operation. For example, the engine’s greater fuel tolerances allow it to handle fluctuations in the thermal quality of the biogas with little or no manual intervention, GE said. These modifications were required to address the unique operational challenges of using biogases and were validated at both landfill and digester biogas-to-energy project sites.

The APG1000 is available for natural gas and biogas applications, with the option of also incorporating Waukesha combined heat and power technology. The APG1000 Enginator gen-set is rated 1014 kW at 50 Hz (1500 r/min) and 1117 kW at 60 Hz (1800 r/min). The 16V150 LTD engine is rated 1038 kW at 50 Hz (1500 r/min) and 1142 kW at 60 Hz (1800 r/min).

“Our introduction of the Waukesha APG1000 biogas engine helps us address the demand for more biogas engine choices in the lower output range as more industrial customers seek to recycle their own waste gases to generate cleaner and more cost-effective onsite power,” said Rafael Santana, CEO-Gas Engines for GE Power & Water.
