Abstract
A novel fluidized bed system is proposed to recover heat from melted blast furnace slag. The melted slag is fed into a fluidized bed of crushed solid slag particles. The heat of slag solidification is transported to immersed heat transfer surface through fluidizing particles. The solid slag clumps, which consist of solidified slag and bed material, are removed from the bottom. A part of the slag clumps are crushed and recycled into the bed as bed material. In the present article, conceptual design of arrangement of heat transfer surface was carried out. Fundamental study of heat recovery from melted wax (simulated melted slag) was conducted using a fluidized bed cold model. Heat balance of the fluidized bed cold model was established.
