Research Abstract

A novel fluidized bed system is proposed to recover heat from melted blast furnace slag. Fundamental study was conducted using a fluidized bed cold model and simulated melted slag. Effect of the properties of melted material on the inclusion of bed material to the solidified simulated slag was investigated. Also hot fluidized bed experiments were carried out using real melted slag(at 1400℃) and high-temperature bed material(600-800℃). Effect of bed temperature on the shape of the solidified material was investigated.
