1 12/15/216 72th IEA FBC Technical Meeting, Tokyo, December 216 Utilization of fluidized bed boilers a worldwide overview B. Leckner, L. Thorson, J. Kjärstad, F. Johnsson Chalmers University of Technology Department of Energy and Environment Göteborg, Sweden 1 HISTORY OF FLUIDIZED BED COMBUSTION FOR POWER PRODUCTION Short version from Leckner, B. (216) Developments in fluidized bed conversion of solid fuels. Thermal Science, 2, 1 18., Calcium looping and other post combustion methods CLC, all fuels Twin reactor FB * Lewis&Gilliland (Cat Cracker, petroleum) all solid fuels all solid fuels PFBC coal biomass&wastes * Single reactor FB * Winkler gasifier, lignite, Gasifiers, YEAR 2 1

2 12/15/216 THE DATA 196 fluidized bed boilers have been collected (small ones omitted) Gasifiers (Just from Valmet. Not included in the plots) Full data of: Country, steam capacity, electrical capacity and main fuel The data have been provided by the boiler manufacturers Alstom, Andritz, BW Volund, Foster Wheeler and Valmet, including the former Metso/Kvärner. Chinese and Indian data have been obtained through the kind help from Prof. Yue Guangxi, Tsinghua University, China, from China Electric Council, and from Mr. Vinod Kumar, IPMA, Indian Power Management Academy, India. 3 BOILERS IN CHINA, 27 Jianxiong Mao, boilers in China, Cleaner coal workshop, 28, Ha Long City, Vietnam Capacity t/h (MW e ) (ordered, under construction and in operation) (25) (5) (75) (9) (1) (135) (2) (3) 31 8 Total in operation 4 2

10 12/15/216 Electric energy produced in Europe 199 and 214 (From IEA World Energy Outlook, 216) 19 FURTHER APPLICATIONS OF FBC AS A SOLID FUEL CONVERTER FBC has shown to be useful for combustion of various fuels Coal Biomass Waste FBC can also serve a a reactor for CO2 removal: Oxy fuel CLC CaC Etc. 2 1

11 12/15/216 CONCLUSIONS The capacity of has grown strongly in China and in other Asian countries related to coal combustion. The size of boilers is reaching utility scale. In Europe is mostly employed for power production from coal in Poland and some are built in Europe for biomass combustion in smaller sizes, suitable for industrial and district heating systems
