EXERCISES AND PRACTICAL POSSIBILITIES TO BE DONE WITH THE MAIN ITEMS
1.- Study of the basis of fixed bed fluidization.
2.- Comparison of the fluidization process in water and air currents.
3.- Study of the pressure drop through fixed and fluidized beds in
function of:
The flow speed.
The size of the bed particles.
Type of fluid: air or water.
4.- Verification of Carman-Kozeny equation.
5.- Study and determination of the minimum fluidization speed.
6.- Study and determination of the fluidization speed and comparison with theoretical calculated values (Ergun equation).
7.- Study of differences between particulate and aggregative fluidization.
8.- Observation of the “bubbling” fluidization phenomenon.
Additional practical possibilities:
9.- Sensors calibration.
Other possibilities to be done with this Unit:
10.-Many students view results simultaneously.
To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
11.-Open Control, Multicontrol and Real Time Control.
This unit allows intrinsically and/or extrinsically to change the span, gains; proportional, integral, derivative parameters; etc, in real time.
12.- The Computer Control System with SCADA allows a real industrial simulation.
13.- This unit is totally safe as uses mechanical, electrical/electronic, and software safety devices.
14.- This unit can be used for doing applied research.
15.- This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
16.- Control of the LFFC unit process through the control interface box without the computer.
17.- Visualization of all the sensors values used in the LFFC unit process.
– By using PLC-PI additional 19 more exercises can be done.
– Several other exercises can be done and designed by the user.
