MINIMAL VELOCITY OF FULL FLUIDIZATION – A NEW DETERMINATION METHOD
KOMUNALNA ENERGETIKA / POWER ENGINERING, 20
The article introduces the method for characterization and control of fluidized beds with wide size distribution of particles. A laboratory unit has been made for the purposes of experimental research. Our goal is to make an automatic control protocol to find minimum necessary flow of fluidization fluid to run the process at full fluidization. On the basis of measured differential pressure and gas velocity, programme can find the optimal operation area. The method determines a single point among many points with almost same differential pressure and various gas velocities. This method can be used for controlling fully fluidized bed at minimum gas flows in CFB gasificators, fluidized bed furnaces, fluidized bed sanding machines, etc.
