Fluidized bed steam boiler is adopts CFB technology mapping, is also a large heat energy equipment through reconstructing the flow of fuidized bed produce high-quality steam, the main types are classified according to the structure, divided into high and low velocity fluidized bed steam boiler.
CFB boiler design with compact separator was first put into commercial operation in 1992. And the compact CFB boilers supplied by ZG is now operating in many countries and the operation of all the CFB boilers are well.
Pioneering CFB technology We have steadily increased unit size and integrated advanced field-proven design features into our CFB technology. Our CFBs first reached small-scale utility application in 1987 on the 110 MWe Tri-State Nucla power project in the U.S., then went on to the medium utility scale in 2001 with the 2 x 300
Foster Wheeler has introduced a new COMPACT Circulating Fluidized Bed (CFB) boiler design based on the rectangular hot solids separator. The Compact design also enables easy implementation of new designs for INTREX fluid bed heat exchangers. These new products result in many benefits which affect the boiler economy and operation. After initial ...
boiler. Since the first sale of this compact separator CFB boiler, Foster Wheeler has sold about 60 CFB boilers with the compact separator design. Up to now, the largest CFB boiler with the compact separator design in operation is the Lagisza 460 MWe supercritical CFB boiler located in Poland. Figure 2. Compact Separator
boiler pass is top supported allowing easy expansion downwards. The second boiler pass has remaining part of the economiser heating surface and the tubular airheater. The elutriated fly ash is separated from the flue gases in cyclone separators located between the boiler first and second pass, at a temperature of around 400 C. It is
without adding external bed material during the operation of a CFB boiler. Therefore, adding kaolin or other minerals during operation is necessary for a biomass CFB boiler, which also can control the agglomeration of bed material at the same time. 12 MW e BIOMASS CFB BOILER Design Specification of the 12 MW e Biomass CFB Boiler
