  • Elutriation an overview | ScienceDirect Topics

    The elutriation rate of unburned carbon is dependent on coal feed particle size distribution (coal fines), char particle size reduction by combustion, coal particle attrition and fragmentation of burning coal particles (Brown et al., 1992). Fine char particles which can be formed during combustion may be entrained by the flue gases and then ...

    Nov 14, 2015· Particle Size Distribution 3. Elutriation Techniques Elutriation is a process of sizing particles by means of an upward current of fluid, usually water or air. The process is the reverse of gravity sedimentation, and Stokes' law applies. All elutriators consist of one or more "sorting columns“ in which the fluid is rising at a constant velocity.
