The Second International Conference on Circulating Fluidized Bed Boiler(CFBB02)

The 2nd International Conference on Circulating Fluidized Bed Boiler (CFBB02) was hosted by Tsinghua University, China, KOSPO-PNU CFBC Research Center & Pusan National University, Korea in 19-23, July. 2019. in Qingdao, China. Professor Chung-hwan Jeon of Pusan ​​National University and Professor Junfu Lyu of Tsinghua University hosted the conference as chairmen. About 240 representatives from China, Korea, Sweden, Italy, Japan, and India participated in this conference. Almost all universities and research institutes, power plants, manufacturers and auxiliary equipment suppliers related to circulating fluidized bed boilers around the world participated in the conference.

CFBB02 consisted of the technical presentation, youth forum, technical tour, award ceremony, and concert.

After the opening ceremony on the 20th, Professor Bo Leckner of Sweden Chalmers University of Technology gave a plenary lecture under the theme of Developments in FBC of solid fuels. Then, there were 17 invited speeches related to the circulating fluidized bed. There were a variety of topics across the industry, including cases of power plant operation failures and improvements, manufacturers’ boiler design plans, the latest research results from universities and research institutes, and new technologies for auxiliary equipment.

On the evening of the 20th, the award ceremony and the special violin concert on the theme of “energy and environmental protection” were successfully held at the Qingdao Oriental Film Capital Theatre. Professor Guangxi Yue from Tsinghua University presented the 83-year-old Professor Bo Leckner with the Special Contribution Award for Fluidization. Professor Fabrizio Scala presented awards to the three best paper winners, namely Runxia Cai from Tsinghua University, Dongfang Li from Pusan National University, and Zhuo Liu from Chongqing University. After the award ceremony, the world-renowned violin master Xiang Chen and piano master Mattieo Fossi presented an elegant auditory feast to the audience.

In CFBB02, the youth forum session, which was not present in CFBB01, was additionally operated. The participants had time to present their submitted papers and answer questions. And the best papers were selected.

On the 21st, there was a technical tour. In the morning, some participants went to Qingdao Songling Power Environmental Equipment Co., Ltd. to visit and study. In the afternoon, the participants exchanged technology with Huadian Group’s Zibo Power Plant, a representative fluidized bed power plant in China. Zibo Power Plant has a 2×145MW fluidized bed boiler, and since it started commercial operation in 2002, through continuous improvement on its own, it has won many awards in competitions in China for its excellent operation and maintenance level. Korea Southern Power conducted in-depth exchanges with Zibo Power Plant on environmental pollutant emission reduction, long-term stable operation, and on-site sanitation management.
On the last two days of the conference, participants toured the Zaokuang Fluidized Bed Power Plant in Zaozhuang, China to exchange technology. The Zaokuang Power Plant has one 350MW supercritical boiler with the latest fluidized bed technology from Dongfang Boiler in China. The overall operation stability and eco-friendliness of the boiler are excellent by using the uniformity-enhanced design. Korea Southern Power had in-depth exchanges with the Zaokuang Power Plant on bottom ash treatment equipment, fly ash utilization plan, and power generation cost reduction.
