Abstract: CFB combustion technology, up to now, is the most commercial clean coal combustion technology, and becomes one of the most important developing directions for coal-fired boiler. With the development of technology, the capacity increases continually, from the industrial boiler, medium capacity utility boiler to large one. Several 200MW to 300MW CFB boilers have been put into operation and the design of 600MW CFB boiler is reliable too. The operating reliability will depend on the stability of refractory material significantly. It introduces the status of scaling-up of CFB boiler, the general situation of CFB boiler in China and the request of refractory materials. Key words: CFB boiler; scaling-up; refractory material CFB20 CFB 1 2070Lurgi 198591Duisberg 95.8 MWe75kg/s ABB-CELurgi 160 MWeWaco 19909199110 ABB-CE SteinFW 80 : 2002-05-08 1965-,100084 9.7220.83kg/s 36.11kg/s 61.11kg/s 135 MW AlhstromEVTFW ABB61.11kg/s CFB 2 2.1Turow3235 MW+3260 MW Turow Bogatynia10200 MWe 30 3235 MWe3260 MWe 2004 3235 MWe 3 Turow 2 200319 1 485 MWe 235 MWe 184.72164.72 kg/s12.82.43 MPa 540235 MWe 280 MWe 1Turow235 MWe 1Turow235 MWe 2 Turow 2235 MWe12 3 456 3260 MWe 2.2Gardanne250 MWe GardanneProvence 19961996 Gardanne250 MWe 194.44 kg/s16.9 MPa 567566140 3Gardanne 300 MW 2.3Jacksonville2300 MWe Jacksonville2300 MWe JEA Jacksonville/ 300 MWe JEA300 MWe /4JEA 300 MWe 300 MWe 100%100% SO2 10%98% 18.3 MPa540300 MWe 3Gardanne 4Jacksonville300MWe 2.4 300 MWe 18 MPa300 MWe 2002600 MWe 13 5FW400 MWe 5FW 400 MWe 3 100 MWe 113.89 kg/s9.8 MPa540 6100 MWe 6100 MWe 400 t/h 125 MW 19100 MW12 50 MW66 4 900 7 Circofluid 500 8 910 1 7 8 () 9 ()10 () 11 15FBC 5 INTREX INTREX INTREX INTREX + 1A5 3.1 A-36 127 6.23 kPa 93SO2SO3 SOx/H2O C-2760.0025 mm 316L317L 53 A 82 A 3.2 A ASTMA-606 3.3 A 18C-276 C-276 Ceilcrete AR Flakeline 103 Ceilcrete AR 3.4FGD FGD 904L A 315 FRP FRP 4 A300 MW 1,.
