The awards for Outstanding Scientific Research Achievements of Higher Education were announced after careful assessment of experts in the same field and examination and ratification of the Awards Committee and the Ministry of Education (MOE). The Research and Application of Key Technology for Chinese Large Thermal Power Generator Networks Air Cooling Design and Operation, a project carried out by Prof. Yang Yongping and his scientific research team, was awarded the first prize.
    The project is actually a deep research on the key technology of Chinese direct large air cooling system design and operation. It consists of a variety of achievements. For example, first laboratory for unit thermal state performance of Chinese air cooling condenser has been set up, simulation software for online diagnostic technology and design and operation of thermal power generator networks performance has been developed, and air cooling technology research support platform with independent intellectual property rights has been formed. Besides, more scientific evaluation system for air cooling condenser performance has been established and the effect mechanism of how factors, like the structure of mixed vacuum condenser, the unit operational parameter and meteorological conditions, influence the performance of air cooling unit has been made clear accurately. What’s more, taking both the natural environment of northern China and characteristics of unit load, Prof. Yang and his research team has developed organization optimization and enhanced heat transfer technology of air flow field, proposed the optimization operation rules for the axial flow fan cluster partition and unit full-scale conditions, lowering backpressure 2-3kpa and reducing fuel consumption 4.5-7g/kwh under the same environment and operational condition, providing technical support for thermal power generator networks air cooling optimization design. At present, the project has achieved great success in the design and operation of 20-plus air cooling units in climate and environment typical to North China, including 300mw sub-critical and 1000mw super-critical thermal power generator networks.
