The Third International Conference on Circulating Fluidized Bed Boiler(CFBB03)

The 3rd International Conference on Circulating Fluidized Bed Boiler (CFBB03) was held at the Westin Chosun Hotel in Busan in 25-26, Nov. 2020, co-hosted by Tsinghua University, Pusan ​​National University and Korea Southern Power. It was held online and offline (Busan) in parallel due to the impact of COVID-19, with about 200 people from all over the world participating. The conference was chaired by Pusan ​​National University Professor Chung-hwan Jeon, and Tsinghua University Professor Hairui Yang participated as the co-chair.

There were presentations by experts from China, Korea, the United States, Canada, Sweden, Italy, Poland, and other countries such as India, Finland, Switzerland, and Japan, as well as IEA (international energy agency)-FBC (Fluidized Bed Conversion) and IEA-Clean Coal Center participated.

At CFBB03, the latest experimental and modeling results of circulating fluidized bed boilers in the field of basic research were introduced, and the design and operating characteristics of the world’s first and largest supercritical and supercritical circulating fluidized bed boilers, improvement cases, and economic effects were announced.

In addition, research on various problems that may occur in circulating fluidized bed boilers, mechanisms, and preventive measures were presented. Inhomogeneity and modeling studies in large fluidized bed heat exchangers and carbon dioxide capture and storage (CCS) technology based on fluidized bed heat exchanger technology were also presented. The latest research results have also been published.

Young scholars presented the latest research results on various topics such as nitrogen oxide emission characteristics from circulating fluidized bed boilers, improvement of desulfurization efficiency, optimization through numerical analysis, and improvement of cyclone efficiency.

Although under the impact of COVID-19, Professor Hairui Yang personally presided over the online technical exchange between Shaoguan Power Plant and Samcheok Power Plant. They conducted in-depth exchanges on the technology and operating experience of CFB boilers.
