Density calculation of a compound medium solids fluidized bed for coal separation According to the equilibrium principle of mass, the equations below apply. [1] [2] Let m = V ∆V, m is the expansion ratio of a fluidized bed. From Equation [1] and Equation [2], the ρf can be expressed as [3] For a single medium solids fluidized bed, ρb and m may be obtained by experiments and therefore ρf ...

What Is a Fluidized Bed? - wiseGEEKTraduire cette page

Fluidized bed systems are often used in coal power plants. The mixture of coal and gas enables combustion at temperatures lower than what typically results in releasing nitrogen oxide. Sulfur pollutants can be captured as well, and such a system also enables coal to burn more efficiently.

Fluidized Bed Boiler - an overview | ScienceDirect .

Due to the bed material inside the boiler, fluidized-bed boilers have high heat transfer coefficients, utilize the entire boiler volume, have a uniform temperature distribution and have a low stable combustion temperature. Fluidized beds are capable of burning very wet fuels and fuel particles of sizes up to 80 mm (van Loo and Koppejan, 2006).
