Experimental data on agglomeration of coal‐ash particles in a fluidized bed have been presented. It has been observed that above the “initial sintering temperature”, the ash particles are defluidized at velocities above their minimum fluidization velocity. The expression for minimum fluidization velocity has been modified by including a force‐term due to the phenomenon of sintering in addition to those due to drag, gravity and kinetic energy.
