Scientific background

1. What is the high-efficiency and low-carbon gas turbine testing device?

Efficient and low-carbon gas turbines are high-temperature, high-pressure, and high-speed rotating thermal turbomachinery. Their internal aerodynamic, thermodynamic, fluid thermal, chemical, and solid coupling are complex, and rely heavily on long-term experiments and data accumulation. A gas turbine is composed of components such as a compressor, combustion chamber, and turbine, and is the most efficient (combined cycle efficiency has reached 64.0%) and cleanest (nitrogen oxide emissions below 25ppm) high-power thermal power conversion device. The gas turbine testing device is a fusion project of multiple sciences, technologies, and engineering. This device can provide a practical and realistic experimental research environment, and is a technological infrastructure for conducting scientific and technological problems, applications, and development research on gas turbines, as well as innovative activities.

2. What is the significant significance of building an efficient and low-carbon gas turbine test facility?

For a long time, China has been deeply constrained by the bottleneck of the blank space of high-power gas turbine testing equipment. There is no fundamental condition for carrying out major scientific and technological problems in gas turbines, and key scientific data and basis cannot be obtained. There is no effective accumulation of technology and talent, and there is a gap of at least 30 years compared to foreign countries. No product has completed the complete process from basic research to use and development, and there is a lack of independent technology, products, and industries. Up to now, China has been stuck in the assembly business obtained through "market technology exchange", without mastering the design technology of gas turbines and the manufacturing and maintenance technology of hot end components. Almost all of the debugging, maintenance, and repair work of domestic gas turbines are completed by foreign gas turbine production and sales enterprises. It is an urgent need for the scientific, technological, and industrial development of gas turbines in China to quickly build efficient and low-carbon gas turbine testing facilities.

Through the construction and operation of this facility, we aim to provide a world-class experimental platform for the efficient utilization of natural gas, clean and low-carbon utilization of coal energy, as well as cogeneration, renewable energy utilization, fourth generation nuclear energy, energy storage, process application, and industrial energy-saving research and development of gas turbine technology. This will enhance the autonomy of related industries and promote the development of emerging high-tech industries.
