Personal Profile: Qian Huang gained his Bachelor degree from Department of Thermal Engineering, Tsinghua University. He is now a PhD candidate in Tsinghua University under the direction of Prof. Qiang Yao and Prof. Shuiqing Li. He started his 1-year visit to LACER in March, 2015. His PhD work is focused on ash evolution and deposition during pc combustion, and he is now working on ash behaviors during pulverized coal combustion in a well-defined flat flame system.
Research Profile: Coal combustion is still the major energy source for many countries. During pulverized coal combustion in practical boilers, ash deposition is the most significant problem for the reason that it causes an increase in wall temperature and also a reduction in efficiency. Therefore, it is essential to understand the mechanisms and dynamic behaviors of coal ash deposition, as a first step towards resolving the problem.
In LACER, a staged flat flame (Hencken) burner is being built with the advantages of well-controlled temperature history and flue gas components.The flexibility for central reducing environment will simulate the environment around coal particles in practical boilers, and it’s interesting to explore the effect on fine PM formation and deposition behaviors. Coals with different ranks will be used to study the ash depositionmechanisms in the system.
