Title
Analysis Solid Flow in a Shaft-Typed Furnace Based on the 2-Dimensional Scale Model
이영재 , 정석광 Young Jae Lee , Suk Kwang Jung
Abstract
In this study particle flow in a shaft-typed furnace was analysed using a 2-dimensional scale mocel. The measured trajectories of burden turned out to be well matched with the calculated one. On lump-only charging, the discharging characteristics of particles at the lower part of the furnace based on the kinematic model, illustrated the "W" type which resulted from the descending speed differences between the middle and wall or center zones. On pellet-lump misting, material and particle segregations by friction always occurred, resulting in "inverted U" shaped discharging profile due to faster descending at wall.
