Method and means for measuring velocity and concentration of particles in a fluidized bed

Method for measuring the movements of particles and gas bubbles and the concentration of the gas bubbles in a gas-solid system, such as a fluidized bed particle system, thereby treating a selected amount of the particle mass with for example a reflecting material, to mix the marked amount into the r...

Beschreibung
Zusammenfassung:	Method for measuring the movements of particles and gas bubbles and the concentration of the gas bubbles in a gas-solid system, such as a fluidized bed particle system, thereby treating a selected amount of the particle mass with for example a reflecting material, to mix the marked amount into the rest of the particle mass, to register with a probe (1) having several receptors (4) each time a marked particle passes by the probe, to compute the received data to thereby calculate the direction of movement, the velocity, the frequency, etc., of the marked particles.
