Areas of Research Interests/ Research Projects

Prof. Zhang has been engaged in basic research on clean coal combustion technology and combustion science for many years, with research directions in circulating fluidized bed boilers, coal powder boilers and burners, combustion pollutant control, chemical kinetics, flame kinetics, microgravity combustion, and energy storage. Some achievements in pulverized-coal fired boilers, burners, circulating fluidized bed combustion, etc. have been put into application. The proposed pulverized-coal (oxygen-enriched) high-temperature air combustion technology can enhance flame stability and reduce NOx emissions, thereby improving the flexibility of pulverized-coal fired boilers. Prof. Zhang is a pioneer scholar in China in the area of microgravity coal combustion research and has participated in multiple microgravity combustion projects. Recently, he proposes and works on high-temperature solid medium heat storage technology based on fluidized bed heating, funded by international cooperation and the Ministry of Science and Technology. So far, Prof. Zhang has undertaken more than 40 scientific research projects and participated in more than 50 scientific research projects, including five projects funded by the National Natural Science Foundation of China, one 863 project, and one key research and development project of the Ministry of Science and Technology for intergovernmental international cooperation. He has won three first prizes for scientific and technological progress from the Ministry of Education and one first prize for scientific and technological progress from the Chinese Particle Society.
