GE5-1 Gas Turbine

and has been designed exploiting the experience the company has gained over the past 20 years with the PGT25, PGT10, PGT16 and more recently with the PGT25+ (High Speed Power Turbine). The design speed of the GE5-2 low pressure turbine is 12,500 rpm, with a capability range from 50% to 105%, which is ideal for direct coupling of GE Energy centrifugal compressors in the 6 MW power range.

COMBUSTOR

The GE5 uses an annular combustor architecture, to achieve the maximum efficiency while maintaining the highest reliability standards. The unit is configured with a DLE combustion system that reduces the NOx and CO emission levels. It consists of a compact annular combustor in Hastelloy X with 18 fuel nozzles. Each fuel nozzle includes a double counter-rotating swirler to optimize fuel mixing and flame stability for extra clean combustion.

This combustion system is designed for operation on natural gas. One fixed, high-energy spark ignitor is used to achieve simple and reliable ignition.
