Comparison of the Effectiveness of a Fluidized Sand Bath and a Steam Chamber for Reactor Heating
Both
fluidized sand baths and steam chambers have been used to heat laboratory
reactors, in particular for studies of biomass pretreatment. In this
study, several aspects of the heating performance of these devices
were compared: time to heat reactors to reaction temperature, the
stability of reactor temperature, and the convection coefficient.
The convection coefficient was determined using correlations and multiple
analyses of empirical data. On the basis of the results presented
in this study, the steam chamber can heat reactors to temperature
in a tenth of the time sand baths can, can maintain a more stable
temperature during pretreatment, and has a convection coefficient
one to two magnitudes greater than that of the sand bath. Therefore
if heat transfer is critical, a steam chamber is advantageous
