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.
