Abstract

Abstract: The dust is generated during the process of bulk materials transferring, which pollutes the transfer station seriously. The entrained air arising from the material flow is the root cause of the dust generation. To precisely predict the entrained air volume during bulk materials transferring is of instructional importance for good transfer station design and dust removal equipment selection. In this paper, the computational fluid dynamics and discrete element method (CFD-DEM) is used to establish the predicting model of the entrained air caused by the material flow and study the factors that affect the entrained air volume. Moreover, the simulation is verified through an application case. The results show that the CFD-DEM method can precisely predict the entrained air volume.

Key words: thermal power plant, coal handling system, material flow, CFD-DEM, transfer station, entrained air
