where Xl is a share of “l“-th granular material in total mass in the system,
m denotes a total mass of mixture of granular materials, Klj(dk) is
a characteristic function of some internal process, fUl(dk) is anunknown
particle distribution of “l“-th granular material and “Δdk “denotes the
length of“k”-th particle class.
Based on knowledge about physical and chemical processes Eq. (1),
it is possible to determine an unknown particle size distribution for different
granular materials in the CFB furnace. Final particle size distribution
is connected with the mass ratios of granular materials Eq. (3),
which are fed to the furnace chamber.
