Molecular formula :
nature : the fluid-particle flow system, the following basic features specific to the dilute phase : (1) higher porosity, typically over 90%; (2) particle pairs containers wall showing a net movement. In this fluid system is greater than the speed of the particles with speed, while flows upward. In fluidized operation, particularly gas-solid fluidization operation, always dilute phase after phase following secret at the same. Strictly speaking, is between two folders also have a middle phase, that is both dense-phase characteristics, characteristics of thin there in the middle phase, it limits the height of the so-called separation of a high degree of entrainment TDH. Generally speaking, people accustomed to the outside dense phase generally known as the dilute phase.
