ROLLS-ROYCE Allison 501 KB5S Gas Turbine – 5 MW, DLE System - 1999

The ROLLS-ROYCE Allison 501 KB5S Gas Turbine, manufactured in 1999, is a single-shaft, axial-flow gas turbine designed for efficient power generation, mechanical drive, and combined heat and power (CHP) systems. Originating from Allison (now part of Rolls-Royce), this turbine is built with rugged engineering and long-lasting, high-temperature alloys for industrial-grade performance.

Capable of operating on natural gas as the primary fuel and diesel or other liquid fuels as secondary options, it delivers around 5 MW of power at ISO conditions and is suitable for both 50 Hz and 60 Hz grids. The unit features a Dry Low Emissions (DLE) combustion system, achieving compliance with strict NOx and CO emission limits.

The multi-stage axial compressor, high operating efficiency, and quick start-up time (10–15 minutes) make it well-suited for continuous and intermittent duty. With an electrical output range of 5 to 7 MW depending on configuration, it integrates seamlessly with compatible synchronous or asynchronous generators.
