11 March 2010 – Caterpillar has launched a new gas-fuelled generator set designed for maximum efficiency in extended duty distributed generation and CHP applications.
Driven by a Cat electronically-controlled, lean-burn reciprocating engine, the 1000 kWe G3512E generator set was designed to offer a high power density and excellent fuel efficiency while maintaining tight NOx control.
The generator set operates at 50 Hz/1500 rpm with Miller Combustion Cycle, is rated at 1000 kWe, and has a standard NOx emissions rating of 500 mg/NM3 at a separate circuit aftercooler (SCAC) inlet water temperature of 54°C.
It is built on a heavy-duty diesel-based platform and uses an advanced camshaft and turbocharger design to achieve high mechanical efficiency. It additionally features an open combustion chamber design, which allows for a low-pressure fuel system of 10 to 35 kPa.
