Caterpillar's XQ1250G natural gas mobile generator set employs a low-emission engine with integrated exhaust aftertreatment
Caterpillar announces the availability of the XQ1250G natural gas mobile generator set. It is rated for continuous operation at 1,250 kW 480/277 V 60 Hz. The Cat XQ1250G is an easily transportable, self-contained, natural gas power plant. It offers a control system to parallel with other Cat generators or with an electric utility.
The XQ1250G power module employs a low-emission G3516B engine with integrated exhaust aftertreatment to comply with July 2010 United States Environmental Protection Agency's New Source Performance Standard for Spark Ignited Engines (USEPA SI NSPS). If local emission requirements are more stringent, the XQ1250G product design is suitable for the addition of aftertreatment devices beyond the standard oxidation catalyst.
The G3516B operates on low pressure natural gas (3-7 psi) and is equipped with an active air-to-fuel ratio controller to allow for varying fuel energy content. With units generating millions of operating hours worldwide, the G3516B engine offers performance with low maintenance costs.
The G3516B engine, fuel regulation components, control and distribution system, and cooling package are housed in a sound-attenuated 40-foot ISO container. It is CSC-certified for nine-unit-high stacking. The XQ1250G offers a fully integrated cooling and exhaust system. The operator can simply connect the natural gas supply line and the load cables to ready the unit for operation. The design of the XQ1250G includes 100% spill containment of all engine fluids.
