Abstract

Heat transfer coefficients were measured for horizontal tube bundles in the freeboard region above an atmospheric fluidized bed of silica sand of 0.86 mm. The average heat transfer coefficients for each tube were correlated well by a simple equation including the effects of static bed height. Comparisons with the previous correlations demonstrate that the present form gives a more accurate and useful approximation for the measured heat transfer rates in the freeboard.
