Application of fluidised beds is more widespread in industry than is usually appreciated, covering such diverse fields as power generation to food processing.
The objective of the F300E Module is to investigate the gas flow through a fixed and fluidised bed and to measure the heat transfer rate and coefficients for comparison with convective heat transfer rates in air.
Fluidisation takes place within a transparent chamber and the range of bed material supplied can be rapidly changed. Alternative locally sourced bed materials and air distributors can be easily utilised for student project work.
A glass cylindrical chamber with an air distribution plate at the bottom end allows the granular material supplied to be fluidised by a controlled and measured air flow.
An adjustable cylindrical heater with surface thermocouple and power meter can be immersed at any level in, or out of the bed to allow measurement of the local heat transfer coefficient. A moveable pressure tapping and separate thermocouple allow the pressure and temperature within the bed at any depth to be measured.
The pressures, temperatures and air flow rate are recorded by a combination of instrumentation on the Compressible Flow Range F300 base unit and the optional module.
