Fluidization and Fluid Bed Heat Transfer Unit The rate of heat transfer from the heater is
must be adjusted for manual electronic control and digitally displayed. Two thermocouples are built into the surface of the element. One of them indicates surface temperature, and the other, in combination with
controller, prevents the surface temperature of the heater exceeding the set value (up to 200 °
Digital temperature indicator with selector displays
element temperature, air supplied to
distributor and movable probe in the chamber of the bed.
Two liquid-filled pressure gauges are installed. One displays air pressure at any level in the chamber of the bed, and
the other shows the pressure drop in the hole, from
which can be determined by higher air flow rates. four sorts of fused alumina (alumina) bulk grains
come with the device and they are suitable for
a wide range of fluidization and heat transfer experiments. An important feature of this device is the ease with which
The material of the bed is subject to change. The block may be in
operation again after two or three minutes.
