Bed-to-wall heat transfer in a 10m2 bubbling fluidized bed

Paper i proceeding, 1994

The heat transfer is measured on the membrane tube wall in contact with a bubbling fluidized bed boiler. Measurements are carried out by heat transfer meters through holes in the wall both in the bed and above the bed in the splash zone and freeboard. Heat transfer coefficients are given and compared with previous measurements of material loss at the same wall and under the same conditions (typical for a fluidized bed boiler)
