26. For gas-solid fluidization systems, the fluidization quality refers to the degree of uniformity in the fluidized bed, that is, the uniformity of gas distribution and gas-solid contact. What are the main factors affecting the fluidization quality of a fluidized bed? A: Gas distribution plate, density of the gas medium, density of solid particles. B: Gas distribution plate, internal structure of the equipment, particle size distribution of solids, and gas velocity. C: Pressure inside the fluidized bed layer, internal structure of the equipment, particle size distribution of solids, and gas velocity. D: Pressure drop within the fluidized bed layer, gas temperature. The issue lies between options A and B; is gas velocity indeed a factor that influences the process? Sorry for the trouble
Factors affecting fluidization quality: Equipment factors, properties of the solid phase, properties of the fluid: density, viscosity A
