Quality Assurance for
Gas & Steam Turbines​

Steam generation can have several sources, such as exhaust gas from gas turbines, iron casting, nuclear power, or other high-temperature sources. The available steam pressure and volume define the turbine design, which includes high-pressure, a medium-pressure, and low-pressure turbine sections. The pressurized steam flows through the blades and vanes to produce mechanical energy to run a generator. ZEISS metrology solutions ensure performance at the highest level and increase efficiency based on various data. Design and performance improvements are the key factors for power generation.

For power generation, gas and steam turbines run at a specific speed that is optimized based on the turbine design and efficiency. This speed level can deviate from the input needed on the generator side. In this case, a speed reduction gearbox is built into the power generation setup to align the speed level and torque of the turbine shaft through the gearbox to the generator. Technology from ZEISS Quality Solutions increases reliability and longevity of the gearbox and its components, reducing costly downtime and repairs.

The generator consists of the rotor, stator and stator housing, and converts mechanical energy into electrical energy. The generator can be mounted directly onto the shaft of the gas and steam turbine or can be driven by the speed reduction gearbox.

Tight tolerances and a small air gap between the stator and rotor are crucial for the overall performance. ZEISS solutions help to enable high efficiency based on accuracy. From blades and injectors to metallurgical and other inspections, ZEISS provides the appropriate solution for your application.
