In the fluidized bed, the particles rise and move round actively by the gases from the bottom of the container. Particles and gases are mixed well in fluidized bed. Therefore, the state in a fluidized bed becomes uniform and can be operated efficiently. However, if the adhesion is caused on the surface of the particles, the fluidization becomes defective. Therefore, it is important to clarify the condition in the state of complete fluidization in the fluidized bed. In this study, the adhesion of the particle surface was operated according to the humidity of air. The adhesion of the particle surfaces is adjusted by changing the relative humidity of the gas into the fluidized bed and fluidization characteristics were examined. The results of the study show that adhesive property has an influence on minimum fluidization velocity and the bed height of fluidized bed.
