Based on the research in the field of the slag waste heat recovery at home and abroad, a new-style technical scheme that the slag waste heat was recovered to preheat the gas based on the fluidized bed was put forward in the paper. The scheme could not only recover the slag waste heat to preheat the blowing-in gas, but also make up the current disadvantage of the single heat source and low-temperature gas supply, and avoid the consumption of fresh water and air pollution in the water flush slag processing. Theoretical research was carried out in the paper to work out the key basic theory of this fluidized bed, the Eulerian-Eulerian continuum model was adopted to research the fluidized bed, which focuses the complex heat and mass transfer accompanied by the process that high-temperature blast furnace slag particles were cooled by air stream, and the key issue is resolved. A high precision multi-function test bench for fluidized bed was built based on virtual instrument (LabVIEW) for further experimental research.
