    It is very necessary to study the drying process of a single lignite particle by high temperature flue gas. Based on finite volume method, the numerical simulation was applied in the lignite drying process and the mathematical model for the drying process of a single spherical lignite particle with high temperature flue gas was developed.

  • Fluidized bed Wikipedia

    A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid. This is usually achieved by the introduction of pressurized fluid through the particulate medium.
