Heat transfer at elevated temperatures,ly the territory of laboratory experiments in order to find out those features which have been described in the preceding chapters. The influence of temperature has two aspects: below 500 °C there is the correct representation of the influence of the changing physical properties with increasing temp

Prediction of the heat transfer in circulating fluidized beds at elevated temperatures,unts to 850 °C. With this temperature the heat flux transferred might be influenced by the radiative heat transfer mechanism [16]. Measurements of the gas/solid flow at elevated temperatures are not easy to carry out in laboratory-scale CFB units because of the handling problems they create. On the

Prediction of the heat transfer with particulate fluidization,s are homogeneously distributed by the fluidizing agent and the fluid dynamic behaviour of the bed can be described by the behaviour of a volume cell containing one particle. As with aggregate fluidization, a flow condition is named where particle-free fluid ‘bubbles’ occur alongside homogeneously d

This change in the flow pattern is reflected by changes in the Reynolds number dependence of other variables, e. g. the single-sphere drag coefficient or the pipe friction factor. Clear relations between these integral data and the Reynolds number, however, are obtained only for geom

And the most significant aspect of solid materials is the very pronounced, sometimes even abrupt, change in their heat capacities with increasing temperature. Figure 11.1 illustrates the significance of all these effects on the heat transfer in bubbling fluidized beds using quartz particles in air.
