- The local time-averaged solids volume fraction was measured in the 12MW~1 Circulating Ruidized Bed (CFR) boiler at Chalmers University of Technology. It was found that the corelwall-layer structure of the flow pattern observed in small-scale beds also characterizes large-scale CFR boilers. The local solids volume fractions close to the wall and in the core region of the furnace were found to be directly proportional to the cross-sectional average solids volume fraetjon, c, as ohtained from pressure rneasurements. If the shape of the membrane-tube wall is taken into account, the relationship for the solids fraction close to the wall (related to a plane wall) is c~=3.6c, which is similar to that reported in literature for plain walls.
