抄録

<p>The residence time distribution (RTD) of coal particles in a gasifier of fluidized bed impacts its energy conversion efficiency. The RTD of coal in continuous bubbling fluidized bed is calculated by extended convection-diffusion model, in which segregation of coal is accounted for. The effect of bed length on the RTD of coal is investigated by this model, and the results are verified by experiments. When the bed length is increased, the dimensionless diffusion coefficient become smaller, and the flow patterns are also changed. Therefore, the bed length effects RTD and energy conversion efficiency of coal.</p>
