Gas Generator Set

Caterpillar Inc offers a Gas Generator Set, G3520E. This is a advanced natural-gas-fuelled generator set, designed for maximum efficiency in extended-duty distributed generation and combined heat and power applications. It is driven by a cat electronically controlled, lean-burn gaseous-fuelled reciprocating engine. It is designed to offer a high power density and excellent fuel efficiency while maintaining tight NOx control. It provides flexibility to operate on pipeline natural gas with a wide range of methane numbers without sacrificing efficiency and performance, and delivers an industry-leading ISO mechanical efficiency of up to 43.5% without water pumps. This generator set operates at 50 Hz/1500 rpm with Miller Combustion Cycle, is rated at 2000 ekW, and has a standard NOx emissions rating of 500 mg/NM3 at a separate circuit after cooler (SCAC) inlet water temperature of 43°C. It is built on a heavy-duty diesel-based platform and uses an advanced camshaft and turbocharger design to achieve high mechanical efficiency. The functionality includes an emergency stop fuel-purge cycle, and programmable protective relaying functions. The generator set is easily tailored to specific applications with a wide selection of Cat SR4B generators and generator set attachments, including oversized and premium generators.
