PRODUCT PACKAGE DESCRIPTION

Horizontal split casing in industrial design, with openings for boroscope inspections.

Single shaft, entirely axial design, cold end drive.

11-stage compressor with transonic 1st and 2n,d stage, compression ratio 19:1, forged wheels,

electronic beam welded, forged single blades with dove-tail fixing, 1st to 6th stage Titan alloy, 7th

to 1 1th stage stainless steal alloy, abrasive aluminum coating of surrounding compressor housing

for minimum gap losses.

Automatic electric/hydraulic guide vane and stator vane angle adjustment on the first 5

compressor stages for Start unloading, mass flow control in part load and for DLE operation.

3-stage turbine, air cooling of entire 1st and 2nd stage with compressor discharge air, air

temperature reduction with pre whirl nozzles for turbine blades, film cooling, zirconium based

thermal barrier coating on entire 1st and 2nd stage, forged turbine rotors with curves couplings,

centre bolt, turbine blades of 1st stage made from directly solidified high temperature investment

casting nickel alloy.

2 journal bearings for radial load, 1 thrust bearing, all tilting pad type. Vibration and temperature

monitoring system, with 2 vibration transducers and 2 thermocouples on each radial Bearing and

1 position transducer on the thrust bearing. Exhaust gas diffuser designed with optimized opening

angle, inclusive temperature and back pressure measurement for the exhaust gas. Temperature

measurement performed with 16 sensor system.

Air inlet collector with opening from top.

3 fastening points designed to compensate the thermal expansion of the turbine section. First

fastening point is positioned near the first journal bearing designed as fix point. Second and third

fastening points are positioned near second bearing and exhaust gas diffuser.
