Global power leader Cummins Power Generation has launched a new lean-burn gas generator set product line. The new 50 Hz products, which extend the capabilities of the existing QSV91G generator range, “offer exceptional transient performance and improved fuel capability”, allowing them to run on low methane number fuels and produce lower emissions. The new line marks the debut of a 2 MWe variant, alongside the improved 1,540 kWe and 1,750 kWe models. Primary applications for the new models include prime, peaking and combined heat and power (CHP), as well as continuous operation in island mode and standby power. Their robust load handling attributes and capability of running on pipeline and low methane number fuels down to 43 MN make them ideal for remote locations where grid power is unavailable, such as mining operations.
In keeping with Cummins’ commitment to a reduced carbon footprint to help meet worldwide emissions standards, NOx emissions ratings as low as 250 mg/Nm3 are available where required. The range retains its proven ability to run on biogases from landfill, digester and sewage sites. In another step-up in performance, the new product line is designed to meet the ISO 8528 G1 standard. The compliance means that the new models deliver improved transient performance with quicker recovery to rated voltage and frequency during start-up and as loads fluctuate. The advance is facilitated by a complete redesign of the generator sets’ turbo layout utilising technology only available from Cummins Turbo Technologies.
An additional major feature of the new line-up is black start capability – the ability to bring the generator set quickly into operation without relying on an external electricity source such as the grid. Black start capability frees the generator set from grid dependency and allows its deployment anywhere there is a need. The new product line is also capable of running in high altitude and high ambient temperature environments with minimal derate.
