Development of the Heavy-Duty Gas Turbine

The heavy-duty gas turbine is the core unit of the clean energy system with high efficiency in the 21st century and longer term.It is significant for the safety,cleanness and efficiency of the energy system.The key technologies of the contemporary gas turbine consist of multi-stage axial flow compressor,clean combustion chamber,multi-stage axial turbine,internal cooling air system,the materials of the nickel-based super alloy blade and manufacturing etc.It is the only way to promote the localization of the core technology of heavy-duty gas turbine by regarding the national demand as guide,concentrating the strength of the whole industry,integrating the self-research and the technical digestion,achieving the break-through in basic science issues and key technique of the gas turbine,and providing common technical support for the domestic industry.
