Beschreibung
Zusammenfassung:	The invention relates to a method for recovering waste heat of fused magnesite molten lumps. The fused magnesite molten lumps are fed into an annular waste heat recovery chamber to be cooled, a bearing device is arranged in the annular waste heat recovery chamber to bear the fused magnesite molten lumps and drive the fused magnesite molten lumps to move in the circumferential direction of the annular waste heat recovery chamber, and the waste heat of the fused magnesite molten lumps is collected by the annular waste heat recovery chamber. The initial cooling temperature of the fused magnesitemolten lumps is 1000-1200 DEG C, when the outer surfaces of the fused magnesite molten lumps are cooled to 200-300 DEG C, the fused magnesite molten lumps are discharged from an outlet of the annularwaste heat recovery chamber to be subjected to shell breaking, and the incompletely cooled fused magnesite molten lumps with the core temperature being 500 DEG C or above enter the annular waste heatrecovery chamber again to r
